Abstract
Aims: The purpose of this study was to perform a systematic review of the literature on the different fixation methods available for sagittal ramus split osteotomy associated with mandibular advancement tested in vitro to evaluate stability of each method.
Study Design: Systematic review.
Methodology: Following the PRISMA model for systematic reviews, a query was made in the PubMed, Bireme and Cochrane Library databases, identifying articles that reported the different fixation methods for sagittal ramus split osteotomy for mandibular advancement.
Results: A total of 352 articles were identified, 11 papers of which, after evaluation in relation to the inclusion and exclusion criteria, were systematically reviewed.
Conclusion: Sagittal ramus split osteotomy is a technique performed for the treatment of mandibular discrepancies in which the methods for fixation of the segments are quite varied. In view of the biomechanical studies, the hybrid technique is the most indicated method, while miniplates with monocortical screws present less stability.
Keywords: Orthognathic surgery, sagittal split ramus osteotomy, mandibular advancement, fixation.
