Bryan Bell, Dr. Stephanie J. Drew, Dr. David L. Hirsch,Dr. Steven M. RoserHandelIncreased access to medical imaging studies and bettersimulation software systems have led to increased usageof virtual surgical planning over the past few years.Simulating complex orthognathic or reconstructionsurgeries can enable greater understanding of thepatient’s condition and confidence in the surgical planprior to surgery. Use of tactile guides, models andtemplates to transfer the clinical plan to surgery havebecome increasingly powerful and efficient.Common applications of this technology includeplanning osteotomies and movements for correction ofcomplex asymmetry in orthognathic surgeries. Clinicaltransfer is accomplished via use of CAD/CAM generatedintermediate interocclusal splints. Service models whichcombine the software, the planning service and templatedesign/ production are providing accessibility to thisadvanced planning technology without the need forsurgeons or orthodontists to have high-tech skills.Advances in Orthognathic Surgery: AcceleratedOsteogenic OrthodonticsSponsored by Piezosurgery, Inc.Dr. Charles D. Hasse, Dr. Gerald R. EidenmullerMozart6ACOMS 32nd Annual Scientific Conference & ExhibitionDuring this session, participants will learn to use the AOOtechnique for rapid set-up of selected orthognathicsurgery cases, understand the difference between boneblock surgeries and the regional acceleratedphenomenon (RAP) osteotomies employed in AOO. Thesession will help demonstrate how to maximize thecommunication between maxillofacial surgeons andorthodontists in treating dento-facial deformities.In-Office Cone Beam Computed Tomography: EssentialTechnology for Oral and Maxillofacial SurgeonsSponsored by Imaging Sciences InternationalDr. Steven A. GuttenbergStraussOral and maxillofacial surgeons must have a goodunderstanding of the anatomy of the jaws prior totreating acquired or congenital tooth loss, dental andosseous pathology and trauma, as well as orthognathicdeformities and skeletally based sleep disease. ConeBeam Computed Tomography (CBCT) offers a threedimensional view of the maxilla and mandible to seemore diagnostic information prior to surgery. This sessionwill help demonstrate how the successful utilization ofthe CBCT can be beneficial for nearly all aspects of a fullscope oral and maxillofacial surgery practice.Avoiding and Managing Complications of ImplantTherapy in the Esthetic ZoneSponsored by BioHorizons, Inc.Dr. Bach LeVivaldiMany variables influence the implant treatment outcomesin the esthetic zone. Patient factors such as periodontalbiotype and tissue display are critical in determining thepotential for success when treating patients with implantdentistry. Additional considerations, including implantchoice, surgical design and restorative design, are amongother critical factors that are in the control of the treatingdentist. This session will demonstrate how to successfullyincorporate implant therapy in the esthetic zone with abroader understanding of the risks and how to avoidthem. A series of cases have been gathered to illustraterisk assessment and predictable management of implanttreatment in the esthetic zone.

Conference Dedicated toProfessor Hugo Obwegeser, MD, DMDIn June 1966, at a time when the specialty was struggling to find relevance andidentity, American oral and maxillofacial surgery was revitalized by a surgeon fromSwitzerland and a series of lectures at Walter Reed Army Medical Center. HugoObwegeser’s description of what is now known as orthognathic surgery captivatedthe industry and imagination of an entire generation of American oral andmaxillofacial surgeons, and his visit to America more than 40 years ago is arguablythe single most important watershed event in the history of oral and maxillofacialsurgery in the United States.The ACOMS 32nd Annual Scientific Conference and Exhibition, “Watershed Eventsin Oral and Maxillofacial Surgery: Celebrating the Past—Embracing the Future” isaptly dedicated to Professor Hugo Obwegeser, MD, DMD, a man of energy andindependence.As described by his long-time friend and colleague, Dr. Bruce MacIntosh:Hugo Obwegeser remains today an example of the complete professional man. The energies thatcarried him from simple Alpine beginnings through his early stringent and self-sacrificing days ofprofessional life following the Second World War, and then through the halcyon days of hisextraordinary clinical and educational career, support him still in his afterglow activities. Now90 years old, he remains an active hunter and outdoorsman, a dedicated internationalist, acongenial bon vivant in any social group, and always a man ready to wrestle intellectually with anychallenger in matters of surgery or specialty education. Beyond his early years, he was not aresearcher, but he has always registered strong support for hard scientific investigation. He remainsconsistently “his own man,” but, on demand, can become the astute politician and effectiveorganizational animal. He remains true to his roots, delights in being an excellent family man, butall the time maintains a world view and variegated interests.Every avenue of endeavor honors its forebears, and Hugo Obwegeser has harvested accoladesfrom surgical groups from every point on the compass . He was not the first influence fromabroad to indelibly brand the American specialty—Kazanjian and Thoma are others who come tomind—but his journey to our shores buoyed, and perhaps saved, the American specialty at a timeof its great vulnerability. Hugo Obwegeser was truly the wind beneath our wings. He was andremains, quite manifestly, the most influential oral and maxillofacial surgeon of our time.

2011 W. Harry Archer Award Winner:Edward Ellis, DDS, MSW. Harry Archer was a trailblazer for oral and maxillofacial surgery who helped to define the specialty by studying andpresenting it in the scientific literature. The W. Harry Archer Award was established by ACOMS to recognize both theachievements of individual oral and maxillofacial surgeons and to recognize the contributions to the specialty byDr. Archer. It is fitting, therefore, that the 2011 Archer Award is given to Dr. Ellis, who has himself elucidated much of ourcurrent understanding of maxillofacial surgical outcomes through application of the scientific method.Dr. Edward Ellis—renowned surgeon, researcher and educator—is the recipient of the 2011 W. Harry Archer Award. Forthe past 25 years, Dr. Ellis has fostered his clinical interests in maxillofacial traumatology, dentofacial deformities anddental implantology into a body of scientific literature that has shaped and reshaped the way surgeons practice today, inthe United States and all over the globe. His indelible contributions to the science of oral and maxillofacial surgery aremanifested in the four textbooks, 40 chapters, 80 abstracts, and more than 100 peer-reviewed manuscripts.Currently, Dr. Ellis is Professor and Chair of the Department of Oral and Maxillofacial Surgery at The University of TexasHealth Science Center at San Antonio, Texas, where he also serves as the Director of the Oral and Maxillofacial Surgeryresidency program. A past president of the American Board of Oral and Maxillofacial Surgery, he continues to serve inleadership roles for numerous national and international organizations, editorial review boards, and educational forums.Dr. Ellis received the Daniel M. Laskin Award twice for his contributions to scientific literature that were published in theJournal of Oral and Maxillofacial Surgery, and he was awarded the American Association of Oral and MaxillofacialSurgeon’s Research Recognition Award in 1997. His influence on the specialty has transcended the treatment paradigmsof virtually every oral and maxillofacial training program in the United States and resulted, in part, to his receiving theWilliam J. Gies Foundation for the Advancement of Dentistry Award and his election into the Royal College of Surgeonsof England.Past recipients of the W.
