Multicenter Study Comparative StudyDo patients treated with bimaxillary surgery have more stable condylar positions than those who have undergone single-jaw surgery?
Because condylar positioning after sagittal split ramus osteotomy of the mandible has been known to affect postoperative skeletal stability, accurate positional assessment of the temporomandibular joint after orthognathic surgery is vital to maximize stability of the surgery. The purpose of this study was to evaluate condylar changes after single-jaw and double-jaw surgeries in mandibular prognathism patients by comparing 3-dimensional angular and positional changes of the condylar heads in groups of patients receiving combined maxillary posterior impaction and mandibular setback and those undergoing only mandibular setback surgeries. ⋯ Condylar angulations are more stable after sagittal split ramus osteotomy of the mandible as an isolated procedure than in combination with the posterior maxillary impaction in treatment of skeletal Class III malocclusion patients. Condylar displacements in both the single-jaw and double-jaw groups are clinically insignificant.

Randomized Controlled Trial Multicenter StudyOpen reduction and internal fixation versus closed treatment and mandibulomaxillary fixation of fractures of the mandibular condylar process: a randomized, prospective, multicenter study with special evaluation of fracture level.
This randomized, clinical multicenter trial investigated the treatment outcomes of displaced condylar fractures, and whether radiographic fracture level was a prognostic factor in therapeutic decision-making between open reduction and internal fixation (ORIF) versus closed reduction and mandibulomaxillary fixation (CRMMF). ⋯ Fractures with a deviation of 10 degrees to 45 degrees, or a shortening of the ascending ramus >or=2 mm, should be treated with ORIF, irrespective of level of the fracture.

Multicenter StudyHemostatic management of tooth extractions in patients on oral antithrombotic therapy.
We examined hemostatic management for tooth extraction in patients maintained on oral antithrombotic therapy. ⋯ A sufficient hemostasis can be obtained in most cases of tooth extraction under anticoagulant therapy with warfarin (INR <3.0) and antiplatelet drugs. Moreover, appropriate local hemostatic methods can be successful when postoperative hemorrhage occurs.

Multicenter Study Comparative Study Clinical TrialPain medication as an indicator of interference with lifestyle and oral function during recovery after third molar surgery.
Purpose This study was designed to assess the impact of taking pain medications, as a more comprehensive indicator of perceived pain, on the extent of interference with lifestyle and oral function during recovery after third molar surgery. Patients and Methods Recovery data after the removal of 4 third molars were available for patients enrolled in an institutional review board-approved, prospective, multicenter clinical trial. A self-administered health-related quality of life instrument, designed to assess a patients perception of recovery for pain, lifestyle, and oral function, was completed each postsurgery day (PSD) for 14 days. ⋯ Conclusions Patients with pain sufficient to prompt taking pain medications were likely to report interference with recovery for lifestyle and oral function. A patients choice to take pain medication appears to be a better indicator of a patients perceived pain and the impact of that pain on recovery than numerical pain scales. This method provides more sensitive behavioral information during the period of recovery after third molar removal.
