BACKGROUND Periodontal diagnosis relies heavily on traditional two-dimensional radiographic assessment. Despite efforts in improving reliability, current methods of detecting bone level changes over time or determining three-dimensional architecture of osseous defects are inadequate. To address these issues, computed tomography (CT) has been explored(More)
BACKGROUND The goal of guided tissue regeneration-based root coverage (GTRC) is to repair gingival recession via new attachment formation. Numerous clinical trials have been conducted utilizing the concept of GTR to promote root coverage. Most GTRC studies have had relatively small sample sizes and have not utilized power calculations to determine(More)
Implant dentistry has been established as a predictable treatment modality with high clinical success rates. Esthetic considerations of implant restorations have been gaining increased interest over the years. The role of periodontal plastic surgical procedures in the creation and maintenance of peri-implant soft tissue heights to facilitate better(More)
PURPOSE Placement of dental implants requires precise planning that accounts for anatomic limitations and restorative goals. Diagnosis can be made with the assistance of computerized tomographic (CT) scanning, but transfer of planning to the surgical field is limited. Recently, novel CAD/CAM techniques such as stereolithographic rapid prototyping have been(More)
PURPOSE To demonstrate the predictability of flapless surgery using navigation surgery. MATERIALS AND METHODS Computer-generated preoperative implant planning was compared to actual placement by CT (computerized tomography) scanning of patients before and after surgery. Once pre- and postoperative coordinates of virtual implants were obtained, linear(More)
OBJECTIVES Lesions causing intraosseous defects in the head and neck region are difficult to diagnose using two-dimensional radiography, and three-dimensional (3D) data provided by CT is useful but often difficult to obtain. Recently, cone-beam CT (CBCT) was made available, with the potential to become a practical tool in dentistry. However, there is(More)
Growth factors such as platelet-derived growth factor (PDGF) exert potent effects on wound healing including the regeneration of tooth-supporting structures. This investigation examined the effect of the local delivery of PDGF-BB when combined with reconstructive periodontal surgery on local wound fluid (WF) levels of PDGF-AB, vascular endothelial growth(More)
In recent years, indications for endosseous dental implants have been extended to include partially edentulous jaws with areas of limited bone density and bone volume. Wide-diameter implants are particularly well suited for these situations. The purpose of this paper was to report on 98 consecutively placed 5-mm-diameter implants without smooth surface(More)
Consistency in clinical decision making may be necessary for reliable assessment of student performance and teaching effectiveness, yet little has been done to examine variation in periodontal diagnosis and treatment planning among dental school faculty. The purpose of this investigation was to examine variation among faculty in diagnosis and management of(More)
BACKGROUND Periodontitis is characterized by extensive destruction of the gingival tissues and associated supporting structures of the teeth. Although the pathogenesis of the various forms of this disease is not completely understood, host-derived proteases are believed to have an important role. In this study, we analyzed human tissue samples from chronic(More)
