- Abstract
- Recently, absorbable plates have been used for various types of facial fractures. However, in the case of mandibular fractures, a large amount of force is applied after fixation. Thus, a firm fixation is necessary. In particular, unfavorable fractures are more frequent in mandibular fractures. Therefore, plates should be strong enough to withstand forces at the time of surgery. The purpose of this study was to determine clinical efficacy and usefulness of unsintered hydroxyapatite (u-HA)/poly (L-lactide) (PLLA) composite system by clinical application and follow-up of fixation in patients with mandible fracture. A total of 13 patients with mandible fractures were assessed for compliance with the selection criteria. Fracture site was confirmed with radiographic findings including X-ray and facial computed tomography images. Subjects who fulfilled all criteria underwent operation using HA/PLLA composite fixation system (OSTEOTRANS; Takiron Co Ltd, Osaka, Japan). After reduction of fracture site through oral or skin incision, we placed OSTEOTRANS plates on fracture line and performed rigid fixation with OSTEOTRANS-MX screws. Followup was performed at 1 week, 1, 3, and 6 months after surgery. Occlusion and mouth opening were checked by physical examination and radiographic finding. We also confirmed bone approximation status, bony gap change, and bone union status. All patients finished every follow-up. They were satisfied with outcomes without complications such as malocclusion, foreign body sensation, or tenderness. This study confirms that OSTEOTRANS can be used appropriately for mandibular fractures.
