The purpose of this study was to determine the effect of ibuprofen on the healing and remodeling of bone and cartilage in the temporomandibular joint of the rabbit. Forty-two rabbits were operated on to create a groove and a hole in the articular surface of both the right and left mandibular condyles. Following surgery, the animals were divided into three(More)
BACKGROUND Bisphosphonates, inhibitors of osteoclasts, have been shown to alleviate many of the devastating consequences associated with metastatic bone disease. However, recent reports have shown that bisphosphonates may cause osteonecrosis of the jaws. Since the publication of these initial reports, the authors have treated several patients with(More)
This study evaluated the results of three methods of managing simulated unilateral dislocated fractured mandibular condyles in the rabbit. The first method consisted of surgical reduction of the fractured condyle to its anatomic position and its subsequent fixation with a titanium plate. The second method differed from the first by completely detaching the(More)
When a bicortical screw is used for the rigid fixation of sagittal split-ramus osteotomy, by definition the threads of the screw should engage in the buccal plates as well as in the lingual plates. In a study of six dry mandibles we found that when 2 and 2.7 mm screws are used in noncountersunk holes, it is almost certain that a thread will engage the(More)
OBJECTIVE Scuba and breath-hold divers are compared to investigate whether endothelial response changes are similar despite different exposure(s) to hyperoxia. DESIGN 14 divers (nine scuba and five breath-holding) performed either one scuba dive (25m/25 minutes) or successive breath-hold dives at a depth of 20 meters, adding up to 25 minutes of immersion(More)
Mucolipidosis type II (MLSII) is a rare hereditary disorder of lysosomal storage. Affected individuals have severely impaired growth and rarely exceed 8 kg for body weight or 70 cm in height. Additional systemic features include; kyphoscolosis, umbilical and inguinal hernias, generalized hypotonia, and murmur of aortic insufficiency. Several oral(More)
Patients undergoing an office-based anesthetic require a thorough preoperative evaluation to identify medical illnesses and undertake appropriate investigations or studies. This article addresses common medical illnesses seen in oral surgery offices and provides insight into their anesthetic management, concentrating on open-airway office-based anesthesia.
PURPOSE The status of implant training in US oral and maxillofacial surgery programs has been reported previously based on data gathered from residency program directors. Since the time of those earlier surveys, however, many new technological and surgical developments have occurred in implant therapy. The purpose of this study was to evaluate the current(More)
The morbidity following conservative management of fracture dislocations of the mandibular condyle is considered, and the theoretical advantages of open reduction discussed. The various methods described in the past are reviewed and a new technique is described whereby a Kirschner wire is drilled into the condylar fragment and then inlaid into the ramus.(More)
