Comparison of material-related complications after bilateral sagittal split mandibular setback surgery: biodegradable versus titanium miniplates.

Purpose: The aim of the present prospective study was to compare material-related complications using biodegradable and titanium miniplates after bilateral sagittal split mandibular setback surgery.

Patients And Methods: The subjects included 200 Japanese adults (67 men and 133 women, age range 18 to 45 years) with jaw deformities diagnosed as mandibular prognathism. All patients were prospectively and consecutively randomized to 2 study groups, receiving biodegradable or titanium fixation plates.
