Matrix miniplate versus locking miniplate in the management of displaced mandibular angle fractures

The purpose of this study was to determine and compare various postoperative parameters like ease of operability, plate adaptability, stability etc., associated with use of matrix miniplate versus locking miniplate in the treatment of displaced mandibular angle fractures.

The study was carried out in the Department of Oral and Maxillofacial surgery, King George's Medical College, GM and Associated Hospital, Lucknow. Total 50 patients were treated and included in the study. These were divided into two groups of 25 each and were treated with two of the standard techniques, i.e., one is matrix miniplate osteosynthesis and other is locking miniplate osteosynthesis. These patients were evaluated for postoperative complications and the differences between the two Groups were assessed.

Patients treated by matrix miniplate showed better recovery phase postoperatively as compared to locking miniplate group.

Based on this study matrix mini plate osteosynthesis may be considered as the better alternative method available for the treatment of displaced mandibular angle fractures.
