INTRODUCTION The purpose of this study was to determine long-term changes in hyoid bone position and pharyngeal airway size after mandibular setback osteotomies. MATERIAL AND METHODS Serial cephalograms of 12 patients who underwent mandibular setback surgery were evaluated preoperatively, at 1 week, 6 months, and 14 months postoperatively, and finally(More)
Free autogenous iliac bone is the most commonly used graft material for an extensive alveolar ridge reconstruction. The application of iliac bone, however, is associated with problems, such as transplant loss resulting from postoperative infection and late bone resorption. A bone-graft material more suitable than iliac bone is therefore still needed. This(More)
OBJECTIVES In alveolar distraction, the bone segment tends to incline palatally or lingually, making rigid control of the segments difficult. The aim of this study was to evaluate the usefulness of a newly developed bi-directional extraosseous alveolar distractor (Medartis V2-Alveolar distractor) for pre- and perioperative vector management. MATERIAL AND(More)
PURPOSE The study was designed to evaluate the outcome of standard arthroscopic lysis and lavage for internal derangement with various levels of severity by comparing the preoperative staging with arthroscopic findings and subsequent success rates. PATIENTS AND METHODS Temporomandibular joint disorder in 23 patients (26 joints) who underwent arthroscopic(More)
The final goal of mandibular reconstruction following ablative surgery for oral cancer is often considered to be dental implant-supported oral rehabilitation, for which bone grafts should ideally be placed in a suitable position taking subsequent prosthetic restoration into account. The aim of this study was to evaluate the efficacy of a standardized(More)
A case is presented of a 67-year-old man with adenocarcinoma of the gastric cardia that metastasised to the temporomandibular joint (TMJ). A carcinoma of the cardia metastatic to the TMJ has not previously been reported. The case is unusual in many respects. The condyle and disc were anteriorly displaced by the tumour, resulting in progressive mandibular(More)
OBJECTIVES One main problem occurring after bone grafting is resorption, leading to insufficient bone volume and quality, and may subsequently cause dental implant failure. Comparison of graft volume and bone density of iliac crest and calvarial transplants determined by animal studies demonstrates significantly lower resorption of bone grafts harvested(More)
AIM The aim of this study was to evaluate the success rate of different techniques of repairing maxillary and midfacial defects according to their extent. PATIENTS AND METHODS In this retrospective study, 47 maxillary reconstructions in 41 patients were reviewed. Evaluation took place an average of 4.5 years postoperatively. The cases were divided into(More)
OBJECTIVE To evaluate the success rate of free calvarial grafts for midfacial reconstruction, the relevance of soft tissue coverage, and the influence of radiotherapy. DESIGN Retrospective analysis. SETTING University medical center. PATIENTS Fifty-six patients (27 tumor cases, 24 trauma cases, and 5 others) underwent bony midface reconstruction using(More)
INTRODUCTION Preoperative planning of mandibular reconstruction has moved from mechanical simulation by dental model casts or stereolithographic models into an almost completely virtual environment. CAD/CAM applications allow a high level of accuracy by providing a custom template-assisted contouring approach for bone flaps. However, the clinical accuracy(More)
