| Abstract | ||
| Introduction: Mandibular angle fractures (MAFs) account for 23% to 42% of all mandibular fractures. The frequent involvement of the angle in mandibular fractures can be attributed to its thin cross-sectional bone area and the presence of a third molar Objectives: The aim of this study was to evaluate clinically and radiologically the use of two dynamic compression miniplates in treatment of mandibular angle fractures using Trocar instrumentation Materials and methods: The study was conducted on ten patients diagnosed with a single mandibular angle fracture indicated for open reduction and internal fixation. The fracture was exposed through transoral vestibular incision and reduced under general anesthesia. Third molar tooth in the fracture line was extracted. Temporary Maxillomandibular fixation was done using 26gauge stainless steel wires with arch bars. One dynamic compression miniplate was fixed on the external oblique ridge. The second miniplate was fixed on the lower border of the mandible using Trocar instrumentation. Results: Pain, edema and trismus decreased significantly over the follow up period. Maximum interincisal mouth opening and bone density along the fracture line increased significantly over the follow up period. Five patients had parasthesia of the inferior alveolar and mental nerve preoperatively. The parasthesia decreased progressively from the fourth week. Postoperative panorama radiographs showed adequate reduction and increase in bone density along the fracture line. No postoperative complication occurred. Conclusion: Two 2.0 mm dynamic compression miniplates are suitable for treatment of mandibular angle fractures using Trocar instrumentation. | ||
