Abstract
INTRODUCTION: Orthognathic surgical correction of the mandible by Bilateral sagittal split osteotomy (BSSO) rectifies dental deformities. Despite its advances, skeletal relapse remains a common complication. AIM: The study aimed to assess skeletal stability following BSSO with mandibular setback stabilized by rigid internal fixation with one four-hole titanium miniplate bilaterally. MATERIALS AND METHOD: A total of nine patients with skeletal class III malocclusions who required BSSO and setback were included. Following the procedure, rigid internal fixation with one four-hole titanium miniplate bilaterally was performed. Evaluation for relapse during the first week, third month, and sixth month postoperatively was performed. RESULT: Posterior and anterior facial height increased mildly in three patients, respectively. Pogonion was stable in all patients, with no significant relapse. CONCLUSION: This study provides insight into low skeletal relapse following BSSO with mandibular setback.
