Recognition and treatment of implant complications
Surgical Mini-Lectures The surgical repositioning of the jaws and the eventual aesthetic and functional results are dictated by the preoperative orthodontic positioning of the teeth. Principles of treatment planning for preoperative orthodontic positioning of the incisor teeth will be discussed. Treated cases will be used to demonstrate the principles and importance of this aspect of treatment planning.

M324 Common Errors in the Management of Temporomandibular Disorders Daniel Laskin, DDS, MS, Richmond, VA Despite many years of concentrated basic and clinical research related to the diagnosis and treatment of temporomandibular disorders (TMDs), clinicians are still having difficulties successfully managing many of these patients. In seeking an answer to this dilemma, one frequently looks for complex explanations without realizing that there are simpler reasons for this problem. Most of the difficulty that we have in treating such patients relates to common errors that are made in arriving at a proper diagnosis and in selecting and implementing appropriate therapy. This presentation will focus on these areas and offer suggestions on how such mistakes can be avoided.
dible can be elongated by intraoral or extraoral devices. The intraoral devices are smaller, do not leave an external scar, and do not cause social inconvenience to the patient. The main disadvantages are less control of vector and the need for a second operation for removal. The fundamental principles of mandibular distraction concerning planning of distraction, location of the osteotomy, control of vector of lengthening, and type of distraction device will be discussed. In recent years, distraction osteogenesis has been applied in treatment of obstructive sleep apnea. The method has several advantages over the other methods, mainly in treatment of young children in order to improve airway and to decannulate tracheostomy. When comparing the extraoral and the intraoral methods, intraoral should always be considered first. However, in severely hypoplastic patients, when 3-dimensional correction is necessary, or when there is limited space along the planned distracted bone, the extraoral device has an advantage over the intraoral device. Our experience with 3 types of maxillary distraction will be presented: 1) the rigid extraoral distraction, 2) the surgically assisted protraction, and 3) the intraoral method. Alveolar distraction osteogenesis introduces a new challenge in reconstructing atrophic alveolar bone with no need to harvest bone graft or to use bone substitutes. The advantages and problematic issues of alveolar distraction as vector control of distraction will be described. We will also present research material on the process of osteogenesis, angiogenesis, and the characterization of membranous bone formation during distraction as well as studies on enhancement of bone formation using TGF-␣ and BMP-2.

M326 Recognition and Treatment of Implant Complications Charles Babbush, DDS, MScD, Lyndhurst, OH This presentation will deal with the clinical treatment of ailing and failing implants. The steps necessary to determine the etiology of failure will be reviewed. Once the etiology has been determined, surgical intervention can take place as long as the etiologic factors can also be reversed. 103
