Welcome Message On behalf of the World Implant Orthodontic Association, it is with great joy to congratulate you on the success of the 2 nd WIOC in conjunction with the 22 nd Annual meeting of the Taiwan Association of Orthodontists in the beautiful city of Taipei. A decade ago, orthodontists from Taiwan, Japan and Korea who foresaw the significance of bone anchorage came together to discuss the evidence based on research and its clinical applications in the name of the Asian-Pacific Implant Conference (APOC). From its first conference in Korea, the APOC became an annual meeting hosted by the three countries for the last 10 years. With the increasing interest in bone anchorage, we decided to broaden our spectrum worldwide and to share cutting-edge information with the top leading orthodontists in the field. The first World Implant Orthodontic Conference (WIOC) was held in Seoul, Korea in 2008, which I believe initiated a new paradigm for future orthodontics. During the last 10 years, all of us involved in the meeting not only shared the knowledge on bone anchorage but also became good partners in leading contemporary orthodontics. I dearly appreciate the endless dedication and belief of every board member of the member countries. We should be proud of our work and how the WIOC has affected orthodontics worldwide. Lastly, I thank the board members of the Taiwan Association of Orthodontists and the executive members of the WIOA for their efforts to host a successful meeting. Young Chel Park, DDS, Ph.D President of the WIOA
Welcome Message from the President of 2 nd WIOC Welcome to the 2 nd World Implant Orthodontic Conference (WIOC)! We are pleased that you were able to join us for what we believe will be an outstanding conference in this beautiful and inspiring city, Taipei. This is not the first time that Taiwan and Taiwan Association of Orthodontists are being hosted international orthodontic conferences, and we are making sure that this is one you can not possibly forget. We guarantee at the same time you will enjoy the hospitality, friendship, and culture of Taiwan. By featuring the conference theme of "World Trends of Anchorage Developments TADs", the dedicated team of organizing committee of the 2 nd WIOC has worked hard to line up the best speakers in the world of orthodontics for a stimulating and outstanding program. We have invited 48 prestigious speakers from 16 countries in Asian Pacific, Middle East Asia, Europe, North America, and South America. The program consists of two days of professional activities including keynote speeches, oral presentations, and poster presentations that will inform on the latest trends in the development of orthodontic temporary anchorage devices, and will bring many opportunities to broaden your spectrum of daily practice in what is not possible today and will likely be possible in coming years. We believe you will find much of value in this conference on how to achieve goals in clinical techniques and academic knowledge in implant orthodontics. In addition to academic and clinical knowledge, however, there are multiple opportunities to receive personal inspiration and expand your sense of fulfillment in every area of life. The 2010 Taipei International Flora Exposition, featuring a theme of "Rivers, Flowers, New Horizons," is set to open in the city of Taipei at the same time during this conference. It is the first such internationally-recognized exposition to take place in Taiwan and the seventh of its kind to take place in Asia. It is our sincere hope that you will be able to enjoy spirit of life, beauty of rivers and flowers, and to explore new horizons at the 2010 Taipei International Flora Exposition. I hope you will join in the many opportunities for fun and relaxation during the conference. All involved in organizing this conference can promise your visit to Taipei and the attendance of the 2 nd WIOC will produce unforgettable memories and pleasant experiences. Eric Liou, DDS, MS President, the nd WIOC Chin-Huei Horng, DDS, MS President, Taiwan Association of Orthodontists
Congratulatory Words to the Taiwan Association of Orthodontists As WFO President, and in the name of my Executive Committee, I wish to congratulate Dr. Chin-huei Horng, President of the Taiwan Association of Orthodontists, his Board of Trustees, his meetings organizing committees and all those who helped bring to fruition the magnificent 22 nd Annual TAO National Meeting and the important 2nd World Implant Orthodontic Conference, in Taipei, Taiwan. This achievement highlights how prominent the TAO has recently become in the orthodontic world. The WFO is very proud to have within its organization such a hard working affiliate. I am aware that Taiwan now has 14 institutes/accredited orthodontic programs educating the new generation of orthodontists. The Taiwan Orthodontic Education System is getting stronger as the years go by. The new generations of orthodontists are different from the previous ones in that they do not need to go abroad to the USA, Japan or Europe to learn orthodontics. I sincerely encourage all the TAO members to actively participate in international orthodontic academic activities to increase the standard of orthodontic care, to meet members of other orthodontic Associations/Societies, and to make the future orthodontic world a better one. The WFO supports its affiliates, such as the TAO, in many ways; one is by promoting the meetings they organize. In turn, WFO also needs the support from all its affiliates. Allow me to state the following regarding the WFO. It has specific objectives; among them are to: elevate the standard of orthodontic care around the world, promote scientific research, disseminate orthodontic knowledge, stimulate accreditation and certification, and support bona fide orthodontists. Only those orthodontists who are active members of their affiliates are accepted as WFO members. I encourage all attendee orthodontists at this meeting who are members of a national orthodontic society affiliated with the WFO to become fellows of the WFO. This process is easy, not expensive, and it will help advance the orthodontic specialty throughout the world. The membership application form can be downloaded from WFO's website, www.wfo.org
As President of the WFO I wish all Taiwan orthodontic colleagues to improve the standard of care they provide to their patients. Thus, I urge you to take advantage of the scientific lectures presented during your Meeting and Conference. The TAO already has established its Orthodontic Board System (TBO). The TBO has a representative in the WFO Committee on National and Regional Orthodontic Boards. With the help of TBO and the other 14 representatives from orthodontic boards around the world, this WFO Committee has developed and published guidelines to aid in setting up national and regional certifying boards (including examination criteria). The WFO will continue to promote these efforts. I wish to encourage each one of you to become certified orthodontists through the Taiwan Board of Orthodontics so that every TAO member can be recognized as a doctor who strives for self-improvement in the quest to become a better orthodontist. The TAO established in July 2009 a program to assist underprivileged children, a project to help mainly orphans so they can receive free orthodontic care. Please accept my congratulations on this achievement. I sincerely wish that all the TAO members will support this project and also the project of the Taiwan Association of Orthodontists Foundation to help the TAO in orthodontic research to meet the challenges of tomorrow's orthodontic world. As President of the WFO, I recognize the contributions that TAO has made to the world of orthodontics; it is a very important affiliate of the WFO. I sincerely hope that the new TAO President, together with the new TAO Board of Trustees, will continue to support the WFO in making the orthodontic world a better one. I wish the TAO great success during the 22nd TAO National Annual Meeting and the 2nd WIOC. To the attendees of these two great meetings, I wish you the best in your future endeavors.

It is more a conceptual guardian than technical options.

Sameshima Dr. Glenn T. Sameshima is Associate Professor, and Chair and Program Director of the Advanced Orthodontic Program at the Herman Ostrow School of Dentistry of the University of Southern California. Dr Sameshima completed his orthodontic training and PhD in Craniofacial Biology from USC, after attending UCSF for his DDS. Dr. Sameshima maintains a part-time private practice in Torrance, California. He has held numerous positions in organized orthodontics nationally and internationally, and is a frequent presenter at conferences and meetings throughout the world. His present clinical research interests include self-ligation, root resorption, treatment outcomes, and ethnic differences. Temporary anchorage devices have revolutionized the orthodontic practice of today, yet TADs are but the latest in a long line of strategies developed within the profession to allow us to use Newton's first law effectively in moving teeth. Anchorage, defined years ago by Harry Dougherty is distance to move and resistance to movement. A 31
corollary to that axiom is anchorage preparation when one tooth moves, all teeth move as a unit. This lecture will describe non-tad anchorage methods both new and old that will enable the orthodontist t o m o v e t e e t h i n t h e p r o p e r direction with the most optimal degree of force. Anchorage can be divided into extraoral and intraoral. Extraoral anchorage is familiar to us all as high-pull, cervical, vertical headgear, facemasks, and J-hook and Hickham headgears. Intraoral anchorage includes the traditional transpalatal and lingual arches, Nance arches, and many other forms of both passive and active fixed appliances. The palate is commonly used as an anchorage unit in distalizing molars; there are many appliances that incorporate this anchorage effectively. Using the dentition to pit one group of teeth against another is a time honored and tested method; within this classification you will find figure eights, lacebacks, etc, etc, More subtle variants of this type of anchorage include rotating molars against the cortical plate, applying elastomeric force modules against different teeth on a short time interval, and varying the thickness of the archwire within a single archwire. Clever but predictable results can be obtained in moving teeth differentially; some examples include Cetlin mechanics, and Mulligan mechanics. Using the lip as anchorage works well in tipping mandibular molars posteriorly using a lip bumper. Interarch anchorage strategies were developed by Charles Tweed and his followers, including Terry Root and Harry Dougherty. Although these methods require absolute patient cooperation, they are still among the most effective ways to retract anterior teeth in the properly selected case. Preparing anchorage in the mandibular arch by tipping back the buccal segments against a fixed maxillary arch (High pull Kloehn headgear, palatal bar, and delayed first bicuspid extraction) using Class III elastics, then using this anchorage to retract the maxillary anterior segment using closing loops and Class II elastics was central to this type of treatment philosophy. The principles of anchorage as taught by Charles Tweed are still well thought of today as evidenced by the popularity of the Tweed courses taught in Tucson, Arizona, twice per year. KAO-01 Diverse Approaches: Advancement of Midface for Crouzon Syndrome Patients Hyo-Won Ahn, Seung-Hak Baek Korea Department of Orthodontics, School of Dentistry, Seoul National University, Seoul, South Crouzon syndrome is an autosomal dominant condition comprising premature ossification of cranial sutures. Usually bilateral coronal synostosis is present, but other sutures can be involved and degree of synostosis can be progressive. The characteristic dysmorphism of Crouzon syndrome is midface h y p o p l a s i a w i t h e x o r b i t i s m, brachycephaly and frontal bossing. Midface hypoplasia occurs in both horizontal and vertical direction and leads to anteroposterior, vertical and transverse deficiency of the maxilla. Treatment planning for Crouzon syndrome must be addressed as part of the staged reconstructive a p p r o a c h a c c o r d i n g t o a g e. When seen early in infancy, the most cases are treated first with floating forehead advancement for decompression of the intracranial pressure. In adolescence, repeated craniotomy for additional cranial vault expansion and reshaping or correction of "total midface", d e f o r m i t y c a n b e p e r f o r m e d. Orthognathic surgery for correction of the remained skeletal discrepancy and establishment of functional occlusion can be done after growth completion. In this presentation, two cases for midface advancement in Crouzon syndrome are shown. The first case is severe phenotype treated with Lefort III advancement and orthodontic treatment only in childhood. The second case is mild phenotype treated with Lefort III/I osteotomy, 2-piece widening of the maxilla and BSSRO after completion of growth. Since Crouzon syndrome has diverse phenotype according to 32
the extent of suture involvement, individualized approach based on the severity of phenotype is most paramount to get good treatment results. KAO-02 Vertical Control Via Total Arch Movement in Hyperdivergent Growing Patients Taehyun Choi Dept. of Orthodontics in Yonsei University Dental Hospital, Seoul Treatment of growing skeletal class II patients is commonly d i v i d e d i n t o 2 p h a s e s w h i c h include growth modification with bionator or headgear followed by fixed appliance. These growthmodification appliances are mainly focused on antero-posterior relation rather than vertical dimensional problem, which we rely on a few appliances such as highpull headgear. Furthermore, as vertical growth last longer than transverse and antero-posterior growth, it should be considered during the second phase treatment of hyperdivergent skeletal class II patients. A s o r t h o d o n t i c m i n i s c r e w s w i d e n e d t h e r a n g e o f t o o t h m o v e m e n t, t h i s p r e s e n t a t i o n will introduce improvement of profile in hyperdivergent young adolescents by total arch movement using orthodontic miniscrews. Considerations and insertion of miniscrews for total arch movement will also be discussed. KAO-03 A Case Report of Unilateral Lingual Posterior Crossbite and Class II Malocclusion Correction with Mini Implants Tae-Hun Kwon, Kyung-Hwa Kang, Sang-Cheol Kim Dept. of Orthodontics, School of Dentistry, Wonkwang university, South Korea Crossbite is an occlusal irregularity where a lower tooth has a more buccal or lingual position than the antagonist upper tooth. Crossbite can involve a single tooth or a group of teeth. There are unilateral and bilateral crossbite. Characteristics of unilateral lingual posterior crossbite are lingual tipping of lower molars and buccal tipping of upper molars, extrusion of upper molars due to absence of occlusal contact and development of mandibular shift. Depending on cause and degree, t h e y a r e c o r r e c t e d b y m a n y methods such as distractionosteogenesis, transpalatal arch, precision lingual arch, criss-cross elastics, orthognathic surgery. Recently, absolute anchorage sysem can be made by mini implant, so that the range of orthodontic treatment is expanding. Therefore, we try to show the treatment case of unilateral posterior crossbite and Class II malocclusion with mini implants.

The development of temporary anchorage devices (TADs) has enabled rigid anchorage to be achieved, and TADs have become widely used by orthodontists in orthodontic treatment. TADs provide rigid anchorage, which could not be achieved by using traditional anchorage systems such as intramaxillary, inter-maxillary or extraoral anchorage systems. The use of TADs has enabled more successful orthodontic treatment with teeth being moved more precisely to an intended site. In the case of traditional intramaxillary anchorage systems, m o v e m e n t o f t h e t o o t h u s e d as anchorage, in other words "anchorage loss", which can lead to unsuccessful treatment results, is sometimes intentionally used in ordinary orthodontic treatment. We often use conceptual reciprocal anchorage, which is the idea that both the objective tooth to be moved and the tooth used as anchorage must be moved when we apply orthodontic force in orthodontic treatment. Storey and Smith proposed a differential force technique based on the idea that the velocity of tooth movement induced by orthodontic force must differ depending on the type of tooth due to difference in the area of the periodontal ligament of each type of tooth. Since orthodontic treatment depends on the reaction of periodontal tissue to mechanical stimulation of orthodontic force, knowledge of the reactivity of the periodontal ligament to the mechanical stimulation is important for considering how orthodontic force should be applied when performing orthodontic treatment. We have been studying the tissue reaction to mechanical stimulation w i t h f o c u s o n m o r p h o l o g i c a l and functional reactions of the microvasculature in the periodontal ligament or subcutaneous tissue to compressive stimulation using animals. In those experiments, we observed sensitive reactions of the microvasculature to the mechanical compression that are related to appropriate bone resorption around the periodontal ligament. In this lecture, I will present results of our research on reactions of the periodontal ligament to mechanical orthodontic force and discuss what kind of and what magnitude of orthodontic force will rapidly and safely move teeth. With the current widespread use of rigid anchorage systems, more precise and appropriate techniques for tooth movement are required. TAO-06 Reconsideration about Anchorage Value and Movement Velocity Koutaro Maki 1989-1995 Teaching Assistant, Dept. of Orthodontics, Showa University 1996-2003 Lecturer, Dept. of Orthodontics, Showa University 1998-1999 Visiting Professor, Dept. of Growth and Development, UCSF 2003- present Chair and Professor, Dept. of Orthodontics, Showa University B o t h l o a d i n g m a g n i t u d e a n d biological response affect the Orthodontic tooth movement. Information such as thickness of cortical bone, density value and/or biomechanical response in individual patient could play helpful role in Orthodontic diagnosis. In this presentation, new method enable to measure bone density with CBCT and individual mechanical analysis based on volumetric data will be demonstrated as basic evaluation for 3D treatment planning. And 34
clinical results of Invisalign and super light force treatment with non-ligature bracket will also be introduced as a question raising a g a i n s t t o t h e c o n v e n t i o n a l treatment. 1. Evaluation from CBCT measurement From the database of CBCT image, cortical bone thickness and density distribution were evaluated. Thicker area and higher density distribution were almost coincident, however, morphological characteristics had no relation with them. 2. Possibility of 3D treatment planning W i t h t h e m e a s u r e m e n t o f EMG activity, biting force and structural information from CBCT, individual mechanical conditions were calculated b y a u t o m a t e d F E M ( F i n i t e Element Method). Distribution of mechanical energy, reaction force at Condyle generated by mastication, and center of occlusal curve (Spee curve) were evaluated. In FE model, without any alteration of muscle loading, biomechanical effect of position and angulations of teeth were determined. Changes in distribution of mastication energy, direction of reaction vector at Condyle and curvature of Spee, as the simulation of orthodontic treatment were also calculated. 3. Clinical impression from Invisalign treatment and Super light force Orthodontics As the Orthodontic appliance w h i c h c o u l d b r i n g c e r t a i n a m o u n t o f d i s p l a c e m e n t, results of Invisalign treatment in extraction cases were evaluated. Differences among with- and without- bowing effect were compared in three dimensionally. With newly developed nonligature bracket system and 40-60g of loading magnitude by 0.012-14 NiTi wire, effectiveness of tooth movement was examined in extraction and non-extraction cases. In some cases, treatment period was reduced radically. Through these 1)-3) findings, necessity of reconsideration for anchorage and treatment method will be discussed.

DOG is originally used to lengthen the long bones, fill the bone defects, and reconstruct skeletal deformities. In 1980s, the technique was introduced to the craniofacial skeleton. The maxillary DOG by using cranially fixed external devices has become an accepted alternative in the treatment of patients of cleft and related craniofacial anomalies, especially with severe maxillary hypoplasia. Substantial hard and soft tissue changes can be attained with this technique, which facilitate the comprehensive orthodontic treatment in cleft patients with severe maxillary retardation. In 35
the rigid external distraction (RED) system, a cranially fixed halo as a point of anchorage to advance the maxilla was connected through the maxillary dentition by an intraoral splint and traction wires. With this system, a predictable and stable maxillary advancement can be attained. It is speculated that the slight flexibility present in the traction hooks of the RED system allows for energy storage, resulting in that continuous force to the m a x i l l a b e t w e e n a c t i v a t i o n s w o u l d b e p r o d u c e d. D O G i s accompanied by simultaneous expansion of functional soft tissue matrix, including blood vessels, nerves, skin, fascia, ligaments, cartilage, periosteum, and mucosa. Consequently, the soft tissue tension generates the force against maxillary advancement by distraction. This resistant force is estimated to be mechanically equivalent to the traction force derived from the RED system. Occasionally, some patients especially with potential severe postoperative scar tissue demonstrate resistance to the maxillary advancement toward the end of the distraction period. With these backgrounds, the force applied to the maxilla and distraction device itself should be biologically and mechanically important, and the measurement of the force applied during activation would be of interest. On the other hand, at removal of distraction device after consolidation period, information of the residual force present should be quite instructive in deciding the methods of retention after DOG. Hence, a longitudinal measurement of the force applied was attempted by using micro-strain gauges fixed within the traction wires of RED system. The maxillary traction force was measured daily for all the patients in whom DOG using RED system was performed, aiming to assess the process of DOG. In this presentation, biological property of the soft tissue in response to the tension stress in DOG will be discussed along with mechanodynamic aspects of DOG. TAO-08 Precision Direct Bonding with KommonBase Akira Komori 1988 DDS from Nagasaki University School of Dentistry 1992 PhD from Postgraduate Research Institute of Nagasaki University 1993 Assistant Professor on Nippon Dental University, Department of Orthodontics 1999 Senior Assistant Professor in Nippon Dental University, Department of Orthodontics 2003 Visiting Assistant Professor in Jikei University School of Medicine, Department of Plastic and Reconstructive Surgery 2005 Senior Assistant Professor in Nippon Dental University Hospital, Division of Orthodontics and Pediatric Dentistry 2007 Associate Professor in Nippon Dental University Hospital, Division of Orthodontics and Pediatric Dentistry 2008 Membership in Orthodontics from the Royal College of Surgeons of Edinburgh 2009 Associate Professor in Nippon Dental University Hospital, Head of Division of Orthodontics 2009 Visiting Professor in University of Ferrara, School of Dentistry, Postgraduate School of Orthodontics Improvements in the customized base design and in the bonding system have allowed development o f a p r e c i s e d i r e c t b o n d i n g system, named KommonBase. KommonBase is characterized by a large bonding base, which can acquire the best fitting and a precise bracket positioning while also enhancing bond strength. There is no need to use transfer trays because of its self-positioning shape. Morphological complexity of lingual surface is a great advantage for applying KommonBase. There are many landmarks on lingual surface of the teeth; cingulum, marginal ridge, linguoincisal edge, lingual groove, etc. KommonBase can achieve seating of bracket position according to the landmarks. Brackets can be positioned easily 36
and accurately by pressing the brackets with explorer. If the bracket is laid on incorrect position, KommonBase can direct it to a correct position. KommonBase consists of three types of resin; high flow filled flowable resin, low flow filled flowable resin, and high flow unfilled flowable resin. High flow f i l l e d f l o w a b l e r e s i n a s s u r e s strong bonding property at the interface between bracket base and resin which can penetrate into undercut of bracket base. Low flow filled flowable resin provides a good handling to prevent drift of reference wire and brackets on laboratory procedure. Most part of KommonBase spread over the lingual surface of the teeth consists of high flow unfilled flowable resin. This extended resin was very thin like a film. Even in the case of occlusal interference, interfered resin can be grinded automatically a c c o r d i n g t o t h e f u n c t i o n o f occlusion, because high flow unfilled flowable resin is softer than filled resin. KommonBase should be bonded firmly throughout orthodontic treatment, and it also should be removed easily without enamel fracture at the end of treatment. Since brackets are bonded closely to gingival tissue, it is difficult to maintain dry field. Although resin adhesive produce strong bond strength, the bond strength of resin adhesive is diminished due to contamination of saliva, which leads to result in bracket failure. Adhesives which do not affected by the presence of water and saliva would clearly be preferred. Resin- reinforced glass ionomer cement is hybrid material of resin and glass ionomer cement. The bond strength of Resin-reinforced glass ionomer cement is not affected by contamination of saliva and water. KommonBase can be applied not only to lingual orthodontic brackets but also to other appliances; labial fixed appliance, transpalatal arch, pendulum appliance, lingual arch, etc. Some clinical trials treated with modified appliances will be presented.

Conventionally, orthodontists use reinforced anchorage, such as transpalatal arch (TPA) plus headgear in the upper arch and lip bumper or lingual arch in the lower arch. However, with the newly developed closed coil spring, which exerting constant forces due to its splendid characteristics, contributing to the concept of differential orthodontic forces, only serial ligature tying (SLT) at the posterior anchorage unit can be effective. Besides, alternatives such as crimpable stopper placement and posterior MEAW application can help a lot in consolidating the posterior anchorage unit. In addition, with flowable composite resin at the posterior segment teeth can be another effective option in clinical preparation for maximum anchorage, without the use of skeletal anchorages or EOA. With this method, invasive procedure and complicated chairside work can be avoided. (2) Furthermore, LH wire leveling can be self-anchorage for rotated tooth correction. (3) Crimpable hook can also be used as dynamic anchorage during i m p a c t e d t o o t h t r a c t i o n. ( 4 ) Other examples of IOA, such as revolving implant. [Discussion and Summary] With LH IOA, anchorage preparation can be simplified. Patients feel comfortable, can easily maintain their oral hygiene, get rid of uncomfortable and inconvenient appliances during the treatment, and most of all, are satisfied with a non-invasive successful treatment result.

Hoi-Shing Luk Medical University Director, Luk's Orthodontic Clinic Clinical Assistant Professor - Chung Shan Diplomate, American Board of Orthodontists Member of The Edward H. Angle Society of Orthodontics, North Atlantic Component Anchorage control is an important issue in clinical orthodontics. Orthodontists demand absolute 41
control of teeth movement but most of us do not fully understand the real picture behind this. They hope the patient comply their instruction to wear the extra-oral device such as headgear. In the other hands, orthodontists place extra miniscrews for their anchorage purpose. However, anchorage preparation b e g i n s f r o m y o u r t r e a t m e n t planning. You can finish most of the cases without using those heavy weapons. Another shocking news is even you use mini-screws for anchorage, the posterior teeth are moving forward when you retract the anterior teeth with incorrect force system design. Frequently, anchorage lost will not only happen during closing space. Anchorage lost begins in the very early stage, alignment of teeth. The force system is not the same in every patient because all malocclusion is unique. Different prescription or different brand of the brackets and special wires will not solve your problem. It is the time for you to think about the interaction between the wire and the bracket (tooth)---- Well design force system is the only key for success. 42
Invited Papers WIOC-01 The Past, Present and Future of Implant Orthodontics Chih-Peng Su University Professional Orthodontic Center in Taipei, Taiwan Clinical Professor of Taipei Medical Visiting Professor of Showa University, Japan Implant orthodontics is a grand specialty with a storied past and exciting present. The first research of temporary anchorage device in dogs was described as early as 1945 by Gainsforth and Higley. Untill 1983, the first clinical case was reported by Greekmore and Ekulund in the literature of the use TADs to intrude and correct the upper incisors. After the mid 1990s, clinicians in the Far East are placing TADs on a routine basis and, nowadays, these innovative new concepts and techniques are increasingly spread to the whole world. Implant Orthodontics could be used in a wide variety of clinical applications as follows: (1) anterior segment retraction & intrusion (2) canine retraction & protraction (3) premolar extrusion, intrusion, retraction & protraction (4) molar uprighting, protraction, distalization, intrusion & extrusion (5) entire dentition distalization (6) correction of midline (7) correction of crossbite (including scissors bite) (8) correction of ectopic tooth (9) as a skeletal anchorage in edentulous area (10) as a reinforced anchorage in in-cooperative patients (11) as a help for pre- or post-surgical orthodontics to save surgical site or to achieve better occlusion. Despite huge advances in clinical applications at present, using TADs with some complications could occur (1) during and following insertion (2) during the loading period and (3) at removal period. Besides, due to mass commercial propagations, it seems to be overused and even wanted to replace conventional o r t h o d o n t i c s a n d s u r g i c a l orthodontics. Owing to the fast developments and innovations of other medical fields, it is possible that the use of new concepts, like well-established tooth-bank system and stem cells development etc., will replace TADs as skeletal anchorage and make implant orthodontics go down in history in the future. The purpose of this presentation is to describe the brief history, show cases to demonstrate the contemporary pros and cons of using miniscrews, and predict the future of implant orthodontics. WIOC-02 World Trend of Anchorage Development - TAD Birte Melsen 1964: Examination for the dental degree (first class degree), Royal Dental College, Aarhus 1971: Jus Practicandi as dentist 1974: The Odontologic Doctorate, Royal Dental College, Aarhus 1971: Acting Head, Department of Orthodontics, Royal Dental College, Aarhus 1972-1975: Associate Professor, Department of Orthodontics, Royal Dental College, Aarhus 1975-Professor and Head, Department of Orthodontics, School of Dentistry, Aarhus 1986-Part time practice in Lübeck, Germany (Adult Orthodontics only) Since my communication in 2005 e n t i t l e d " S k e l e t a l a n c h o r a g e where are we?' the application of skeletal anchorage has developed dramatically. The numbers of TADs are increasing and the number of papers, mostly case reports, has grown exponentially. The failure rate reported does nevertheless reflect insufficient knowledge of factors 43
contributing to the failure rate. Factors like type of TAD, cortical bone thickness insertion and loading have been mentioned. A learning curve reported on this, but without a clear definition of the factors leading to reduced failures. Studies of large patient groups may identify some factors of importance, but the number of possible variables may reduce the value of such studies. A separate analysis of the roles played by TAD, doctor and patient is necessary, if the failure rate is to be reduced. Given a certain quality of bone and a standardized loading the influence of different designs can be analyzed. The transfer from primary to secondary stability can be analyzed following standard loading of one type of TAD in an animal model. The influence of the host, the patient who receives the TAD, can only be obtained by collecting information on the patients who have lost one or more TADs. The lecture will attempt to analyze the role of the TAD: of the handling including insertion and loading; and of the host, the patient, including insertion site and bone turn-over. WIOC-03 The Combined Orthodontic and Surgical Management of the Alveolar Ridge Augmentation Using Distraction Osteogenesis and TADS Dror Aizenbud Orthodomtic and Craniofacial Center, Graduate School of Dentistry, Rambam Health Care Campus and Faculty of Medicine Technion, Israel Institute of Technology, Haifa, Israel. A l v e o l a r d e f e c t s c a n r a n g e f r o m s m a l l i s o l a t e d a r e a s t o extensive areas of bone loss involving the entire arch mostly due to congenial anomaly, tumor resections, traumatic avulsion of teeth, periodontal disease or alveolar bone loss post extraction. Distraction osteogenesis is a biological process of new bone formation between the surfaces of bone segments that are gradually separated by incremental traction. This procedure is currently in use to increase vertical and transversal bone volume of the alveolar ridge in traumatic and congenital anomaly patients, while the soft tissues are also reconstructed during its application. However, alveolar ridge augmentation through distraction most often ends in a straight and flat alveolar ridge structure rather than a curvature line augmented b o n e. Te m p o r a r y a n c h o r a g e devices (TADs) may be inserted into the regenerated segment enabling multidirectional orthodontic force application to control the distraction vector thus achieving the proper alveolar ridge architecture. The aim of this presentation is to describe the multidisciplinary approach applying a surgical, o r t h o d o n t i c a n d r e s t o r a t i v e m a n a g e m e n t p r o t o c o l. T h e technique begins with preliminary orthodontic treatment of leveling and alignment of both the maxillary and mandibular dental arches. Alveolar distraction osteogenesis is then applied for augmentation combined with TADs' insertion. The application of TADs for best anterior segment curvature enables dental implant insertion, better positioning and restoration. The results are good aesthetics, functioning and occlusal relationships. 44

O r t h o d o n t i s t s c o n s i d e r t h a t treatment of very difficult cases using implant is trendy. Closing a n t e r i o r o p e n b i t e, i n t r u s i o n of molars or treating mutilated m a l o c c l u s i o n m a y a l s o b e considered trendy in orthodontics. However, do patients feel it? Naah On the patients' side, some patients may consider the beautiful face rather than perfect occlusal interdigitation, the trendy issue for them. The trendiest issue for the patients might be having a beautiful face within 3-4 months. Moreover, can they have beautiful face within 3-4 months time without any braces showed and also without pain? Would that be really really hip for the patients? This presentation will discuss about all new technologies combined w i t h i m p l a n t o r t h o d o n t i c s t o achieve beautiful face first. Then, the alignment will be finished without any obvious braces. These new technologies include clear aligner, pain free low-to-no friction brackets or even no bracket and biomechanics of tooth movement with implant. It will transform TAD from trendy topic to "the world real trendiest orthodontics." WIOC-05 Lessons learned from Animal Experiments for Using Miniscrews Jane Chung-Chen 1983-1989: National Taiwan University Taipei, Taiwan 1989-1991:NTU Hospital Taipei, Taiwan 1991-1997: UC, San Francisco 1996-1999: UC, San Francisco 1997-1999: UC, San Francisco 1999: UC, San Francisco 1999-2000: Dental Department, NTU Orthodontics 2000-2008: Dental Department, NTU 2004: Grad. Program in Oral Biology (joined appointment) 2005-2008: Grad. Program in Clinical Dentistry Assistant Professor 2008: Grad. Program in Clinical Dentistry Associate Professor Animal experiments can avoid ethics problems with human studies. Animal experiments were performed to address: 1) With intentional direct root contact during insertion, what is the tissue response and whether this affects the stability of miniscrews? 2) What is the consequence of miniscrew or root undergoing c o l l i s i o n d u r i n g o r t h o d o n t i c treatment? 3) Will the stability of miniscrew be compromised, if it is loaded with a moment during orthodontic treatment? In order to keep the experiments under the same condition, titanium bone screws, 2 mm in diameter and 11 mm long (Leibinger, Freiburg, Germany) were implanted into mongrel dogs. Screws were given various conditions to address those three issues. Mobility, removal torque and histological sections were examined. Based on these data, we recommend that 1) screws can be planned to insert in the interradicular space only if there is a sufficient space for clearance between roots, since root touching will create higher risks for failure. 2) extensive root movement towards the miniscrew should be avoided. Titanium screw created a shallow concavity on root if tooth was moved against the screw during orthodontic treatment. 3) Moment loaded on the screws may be harmful. Though the stability of 45
certain screws loaded with either clockwise or counter-clockwise moment seemed to be affected, the removal torque value of the screws which remained until the end of experiments did not reach statistical significance when compared to the control group. WIOC-06 3D Imaging and It s Role in Implant Planning in Orthodontics Chung How Kau Professor Kau is Chairman and Professor with Tenure in the Department of Orthodontics at the University of Alabama in Birmingham. He is an active clinical practioner and researcher with a keen interest in three-dimensional and translational research. He actively contributes and publishes in the orthodontic literature and currently has over 100 peer-reviewed publications, conference papers and lectures. 3D CBCT imaging has become a popular tool for diagnosis and treatment planning in orthodontics. This lecture will focus on the use of this technology in imaging the maxillo-mandibular region for temporary anchorage device (TAD) placement. It also depicts some of the clinical results after CBCT evaluation and makes suggestions on the use of CBCT technology for favorable sites for TAD placement. WIOC-07 Can 3-D Modeling and Finite Element Analysis Be Used as Clinical Tools for Planning Miniscrew Placement? Peter Wing Hong Ngan Pediatric Dentistry, Cert. in Ortho, Pedo and Hospital Dentistry, (U. Penn), Diplomate, Diplomate, Amer. Board of Orthodontics. Amer. Board of Stability of miniscrew implants depends upon good mechanical interlocking between the screw and the bone. Bone is subject to fatigue, especially when dynamic or excessive force is applied. The integrity of the peri-implant bone affects the long-term stability of miniscrew implants. Placement of the screws as well as the design including the depth of the threads, the edge of the threads, the shape and diameter have all been shown to affect the frequency of screw failure in the clinic. Currently, the planning of miniscrew placement is limited to the use of clinical judgment in addition to 2D panoramic radiographs. The use of digital radiography can overcome some of the problems of image distortions resulting from magnification or image noise and reflections, but stress and strain distributions under orthodontic force application cannot be determined. Modern medical imaging, modeling and finite-element analysis (FEA) solutions can provide powerful tools for optimizing 3D morphology from radiographic scans and determining stress and deflection distributions for complex anatomical geometries such as bone. The speaker will discuss the use of 3-D modeling and FEA to determine the stress profile on the miniscrew implant and peri-implant bone upon application of orthodontic force. In addition, the effects of orthodontic bracket hook length and angle of force application on resulting stress response of PDL will be used as examples on how these modern tools can be used clinically to plan for miniscrew placement.

(1999-2005) M e t a l - b a s e d i m p l a n t a l l o y s h a v e b e e n w i d e l y u s e d a s artificial implants such as dental implants, mini-implants and metal plates. Among them, titaniumbased ferrous-based alloy are commonly applied as materials of mini-implants. Because the formations of native oxide films a r e i n v e s t i g a t e d a s t i t a n i u m exposures in air environment, the oxide film possesses excellent biocompatibility. Furthermore, several studies have demonstrated that as increasing the thickness of the oxide layer, hemocompatibility of the oxide layers was obviously improved obviously. It also shows 47
that the titanium surface containing oxide layer, so there is characteristic that has finer biological compatibility more than other metals. However, the native oxide is too thin, resulting in being not able to prevent relation of metal ions. Therefore, there have many surface treatment methods such as machinery processing, functional processing, physical vapor deposition, sandblasting, thermal oxidation, and acid etching. All of them, the other purposes of the surface treatments are to enhance the anchorage capability. However, mini-implant is kind of temporary biomedical implant. How to enhance the anchorage capability of mini-implants and remove the mini-implant easily is an important issue. Consequently, this study has two objectives. First, this study investigates the possibilities and limitations of surface treatments for controlled anchorage capability of mini-implants. The optimal functional processing will be discussed serially. Second, this study examines the use of optimal surface modification to enhance the blood compatibility of mini-implant. Properties of untreated and treated mini-implants were evaluated by material analysis and biocompatible test, and animal test. WIOC-10 The Practical Application of Temporary Skeletal Anchorage Device (TSAD) in Dental and Maxillofacial Fields Satoshi Kozato 1997: School of Dentistry, Aichi-Gakuin University (D.D.S.) 2003 Graduate School of Dentistry, Aichi-Gakuin University (Ph.D.) 2003-2009 Deputy Chief of Clinic, Kozato Dental and Orthodontic Clinic 2003-2006: Part-time Research Associate, Department of Orthodontics, School of Dentistry, Aichi-Gakuin University 2003- Part-time doctor, Department of Oral and Maxillofacial Surgery, Kagawa Prefectural Central Hospital 2006- Part-time lecture, Department of Orthodontics, School of Dentistry, Aichi-Gakuin University 2008- Part-time doctor, Department of Plastic and Reconstructive Surgery, Kagawa University Hospital 2009- Kozato Orthodontic Clinic It has already become widely common in the use TSAD in various orthodontic treatments. TSDA is absolutely necessary for the patients with severe orthodontic problems. Because of its stability, even in the limited uses in oral and dental regions, it has also drawn the clinical interests of other dental and maxillofacial fields for its usefulness. While searching for a better success rate with TSAD, there has been research concerning which screw types and surface situations work best. I would like to introduce a new idea in novel screw type TSAD and, then second, the other uses and methods that TSAD have potentials in other fields. I hope that these utilities could help you improve your orthodontic treatments better. One idea on screw shape No matter how much money or effort you spend on researching screw types and surfaces that doesn't mean that you will receive the desired results. It was found that use of already processed screws that were currently being used caused the success rate to increase. by performing full body anesthesia It is common when someone has an accident and receives a large facial injury or has facial burns there are facial tears caused by damage and that makes it difficult to secure tracheal tube in place that is required for airway management. Using TSAD secure and easy capabilities, we can manage a stable intraoral jaw bones, mainly maxilla, where the tube for airway in anesthesia can be secured safely and certainly, further, making later surgeries possible. 48
use for sleep apnea syndrome(sas) NCPAP and Oral Appliance can be used for light and mild cases of SAS. However, there were some patients that while using these had a sense of incongruity and were not able to use them.$b!!(bbecause of their inability to use traditional methods to cure their affliction and the overwhelming effect it had on their daily lives, TSAD may offer a different option and can be used with the purpose of creating airways. As an orthodontic surgeon and from a clinical stand point of view, I would like to lecture on the topics above. TSAD could give orthodontic surgeons the novel chances to participate in and contribute to other dental and maxillofacial fields. WIOC-11 With a Little Bit of Help from My Friend Loh Kai Woh Dr. Loh graduated from the University of Singapore in 1976 and obtained his master of dental science from the University of Pittsburgh in 1982 through a scholarship awarded by the National University of Singapore. He was a full time instructor at the National University of Singapore till 1986. He founded the Association of Orthodontists, Singapore in 1991 and was the president for the first 2 years. He is the President of Asian Pacific Orthodontic Society 2010-2012. Dr. Loh has given presentation in Malaysia, Indonesia, Vietnam, Singapore, Japan, Thailand, China, Philippines, Taiwan, Australia and South Korea. He was a keynote lecturer at the 7th International Orthodontic Congress held in Sydney, in February 2010. In all orthodontic mechanics, anchorage is perhaps the most i m p o r t a n t c o m p o n e n t o f t h e whole biomechanic system. Many failures in orthodontic treatment are due to inadequate preparation for anchorage. In some cases, orthognatic surgery and extractions are indicated mainly because proper anchorage cannot be achieved. All extra oral anchorage depends on patient's cooperation. In cases where such cooperation is not fulfilled, the orthodontic results can be disastrous. With a little bit of help from our friend, the orthodontic mini implant, what were impossible to be treated b e f o r e, c a n n o w b e t r e a t e d. Extraction cases can be converted to non extraction cases. Teeth can be moved to distal end saddle areas. Uneven incisal plane can be leveled. Scissors bite of the upper 2 nd molars is a common problem. In the past, such teeth were often removed but, they can now be saved. Treatments for patients with multiple missing teeth were always a problem, but now, they are more manageable. Even orthognatic surgery cases can be avoided when orthodontic mini implants are used. Mini implant anchorage is truly an orthodontic revolution. WIOC-12 Non-Surgical Treatment for Various Skeletal Malocclusions with Skeletal Anchorage System Junji Sugawara 1973: Graduated from Tohoku University 1973: Instructor of the department of orthodontics at Tohoku University 1981: Visiting assistant professor at the University of Connecticut 1991: Associate professor at Tohoku University 2006 - Present: Visiting professor at the University of Connecticut 2007- Present: Director, SAS Orthodontic Centre, Ichiban-cho Dental Office, Sendai, Japan The Skeletal Anchorage System (SAS) consists of orthodontic miniplates and monocortical screws that are temporarily implanted in the zygomatic buttress or the mandibular body, or in both, as a b s o l u t e a n c h o r a g e s. S i n c e miniplates are placed outside of the dental arches, they do not disturb teeth movement of any kind. The most distinguished feature of the SAS is it enables us to predictably 49
move molars with ease as we can move teeth in the anterior dentition. Therefore, it has become possible to camouflage skeletal malocclusion that has been recognized as an indication for orthognathic surgery in conventional orthodontic diagnosis. Furthermore, as SAS is a noncompliance appliance and functions like an invisible headgear, it is extremely effective biomechanics for adult orthodontics. In this conference, I will principally focus on skeletal Class II openbite and Class III patients who require SAS biomechanics for camouflage. For instance, intrusion of the upper and lower molars with the application of SAS is effective to correct anterior open-bite with skeletal Class I or Class II facial type. Distalization of molars and/ or entire dentition is useful for improvement of Class II or Class III malocclusion with or without mandibular asymmetry. Thus, we can significantly decrease the number of orthognathic cases. The SAS has become an indispensable modality to camouflage any type of malocclusions with skeletal d i s h a r m o n i e s i n o u r c l i n i c a l orthodontics. WIOC-13 Extreme Orthodontics: Application of Micro-Implant for Orthopedic Correction Won Moon UCLA School of Dentistry, Section of Orthodontics, Certificate in Orthodontics, 1991 UCLA School of Dentistry, Section of Oral Biology MS, 1991 Harvard School of Dental Medicine, D.M.D., 1989 University of California, Irvine, BS in Mathematics, 1984 The primary aim of this presentation is to explore and to expand the a p p l i c a t i o n o f M i c r o - I m p l a n t Technology in orthopedic correction of maxillofacial complexes rather than limiting its use only as an anchorage device. Clinical and mechanical obstacles associated with orthopedic correction utilizing the conventional orthodontic t r e a t m e n t m o d a l i t i e s w i l l b e e x p l o r e d, a n d s e v e r a l n e w approaches eliminating these problems by the use of Micro- Implants will be presented.

T h e s e c o n d a r y a i m i s t o demonstrate the application of Micro-Implants in Non-Surgical c o r r e c t i o n o f m a l o c c l u s i o n s manifested by skeletal disharmony. Several clinical cases will be presented and examined in detail. It is clear that orthopedic correction is possible in 3-D when utilizing the Micro-Implant Technology. The use of growth modification technique in conjunction with this new device opens doors to many new possibilities. The Micro- Implant technology brings exciting new dimensions to the discipline o f o r t h o d o n t i c s. D e s p i t e t h e enormous popularity and interests it commends, we have only seen the tip of an iceberg. Many more research and clinical studies are necessary in order to fully understand the impact it will have on all of us.
