An in vitro comparison between two different designs of sagittal split ramus osteotomy
OBJECTIVES To evaluate the influence of the type of osteotomy in the inferior aspect of the mandible on the mechanical performance. MATERIALS AND METHODS The study was performed on 20 polyurethane hemimandibles. A sagittal split ramus osteotomy (SSRO) was designed in 10 hemimandibles (group 1) with a vertical osteotomy in the buccal side (second molar level) and final osteotomy was performed ...
متن کاملEndoscopic-assisted medial osteotomy during sagittal split ramus osteotomy.
In this article, we describe endoscopic-assisted medial ramus osteotomy during sagittal split ramus osteotomy (SSRO). Surgical repositioning of the mandible by bilateral SSRO has become a safer and more reliable procedure through ingenuity of surgical methods, development of special instruments and improvement of surgical skills. The horizontal medial osteotomy should be located at or just abov...
متن کاملUnilateral intraoral vertical ramus osteotomy and sagittal split ramus osteotomy for the treatment of asymmetric mandibles
In surgery for facial asymmetry, mandibles can be classified into two types, rotational and translational, according to the required mandibular movements for surgery. During surgery for rotational mandibular asymmetry, a bilateral sagittal split ramus osteotomy (BSSRO) may cause a large bone gap between the proximal and distal segments as well as condylar displacement, resulting in a relapse of...
متن کاملcorrelation between gonial angle and different variables after bilateral sagittal split ramus osteotomy
statement of problem: the gonial angle plays an important role in ensuring a harmonious facial profile. changes in this angle especially after surgery may be an aesthetic concern for both the patient and the surgeon. purpose: the aim of the present study was to evaluate gonial angle changes after mandiblular setback with the bssro technique and to measure postsurgical relapse two years after su...
متن کاملPosition of mandibular canal and ramus morphology before and after sagittal split ramus osteotomy.
PURPOSE The purpose of this study was to evaluate changes in the mandibular canal and ramus morphology before and after a sagittal split ramus osteotomy. PATIENTS AND METHODS The subjects were 30 patients (60 sides) with mandibular prognathism who had undergone bilateral sagittal split ramus osteotomy setback surgery. The mandibular canal position and ramus morphology were measured at the 3 h...
