    Abstract

    Purpose The purpose of this study was to determine whether a resorbable poly-L-lactide (PLLA) miniplate system could be used to treat mandibular condylar process fracture. Patients and methods Fourteen patients (12 males, 2 females, aged 23.1 ± 5.7 years) who had mandibular condylar process fractures treated with PLLA implants were recalled for follow-up clinical and radiologic examinations at 3 years. Results Mouth opening recovered to more than 35 mm and occlusion was stable in all patients. There was no facial asymmetry 3 months postoperatively. Two patients had mild chronic postoperative tenderness at the implantation site; however, there was no wound infection. All fractured mandibular condyles showed anatomic good reduction and long-term stability with the use of resorbable miniplates and screws. Bone healing was satisfactory in all patients, and there was no evidence of abnormal resorption of the condylar process. The screw holes remained evident after 3 years. Screw holes in 2 patients showed enlargement on radiographic examination. Conclusion The PLLA miniplate system provides reliable stability when used for the fixation of mandibular condylar process fractures.
