Differences in bone remodeling using demineralized bone matrix in bilateral sagittal split ramus osteotomy: a study on volumetric analysis using three-dimensional cone-beam computed tomography.

Purpose: The aim of this study was to examine the effects of demineralized bone matrix (DBM) grafts on bone remodeling during sagittal split ramus osteotomy by measuring 3-dimensional (3D) reconstructed images.

Patients And Methods: Forty-eight patients were selected for this study. In the control group, no grafts were performed.

Usefulness of the retromandibular transparotid approach for condylar neck and condylar base fractures.

Condyle fractures represent 20% to 30% of all mandibular fractures and are thus among the most common facial fractures. The fracture pattern can vary greatly and may occur anywhere along the line from the sigmoid notch to the mandibular angle. The main problems are access, difficulty in repositioning the extremely slender fragments, and fixation of the condyle.
