We assessed the usefulness of newly developed biodegradable Poly-L-Lactide (PLLA) bone mini plate and screw system for internal fixation of the fracture of the mandible. Biodegradable PLLA bone mini plate and screw system was performed on 9 patients (8 males and 1 female) in our department during 1.5 years from January, 1998 to June, 1999. The ages of patients were ranged from 13 years old to 33 years old (mean 22 years). In our series, no postoperative complications were found as a result of using bioabsorbable materials. We believe PLLA bone plate and screw system is safer and more effective and more valuable for the fracture of the mandible.
