Comparison of standard miniplates and locked miniplates in post-traumatic fracture stabilization

Abstract

BACKGROUND: Bicortical screws (lag and positional) or miniplates with monocortical screws are generally used for the rigid fixation of the sagittal split ramus osteotomy (SSRO) in maxillofacial surgery. However, in this osteosynthesis method, the plate must be perfectly adapted to the bone to prevent misalignment of the bone segment and occlusal changes. In addition, it is necessary to prevent the position of the condyle in the mandibular fossa from changing after fixation. In recent years, locked miniplate systems have been used to overcome these complications.
