Mechanical evaluation of the use of conventional and locking miniplate/screw systems used in sagittal split ramus osteotomy
OBJECTIVES The aim of this study was to compare the mechanical resistance of four different osteosyntheses modeled in two different sagittal split ramus osteotomy (SSRO) designs and to determine the linear loading in a universal testing machine. MATERIALS AND METHODS An in vitro experiment was conducted with 40 polyurethane hemimandibles. The samples were divided into two groups based on oste...
متن کاملHorizontal changes in the condylar head after sagittal split ramus osteotomy with bent plate fixation.
OBJECTIVE The purpose of this study was to evaluate the horizontal changes in the condylar head with bent plate fixation after sagittal split ramus osteotomy (SSRO) with and without a Le Fort I osteotomy. STUDY DESIGN Of 47 Japanese patients with mandibular prognathism, 24 underwent SSRO and 23 underwent SSRO in combination with a Le Fort I osteotomy. A 3-5-mm gap was made between the proxima...
متن کاملComparative analysis of the amount of postoperative drainage after intraoral vertical ramus osteotomy and sagittal split ramus osteotomy
OBJECTIVES The purpose of this retrospective study was to compare the amount of postoperative drainage via closed suction drainage system after intraoral vertical ramus osteotomy (IVRO) and sagittal split ramus osteotomy (SSRO). MATERIALS AND METHODS We planned a retrospective cohort study of 40 patients selected from a larger group who underwent orthognathic surgery from 2007 to 2013. Mean a...
متن کاملPostoperative migration at the individual osteotomy site following sagittal split ramus osteotomy: a stereometric radiographic study.
The aim of the present study was to evaluate whether migration occurs at individual osteotomy sites following sagittal split osteotomy of the mandible stabilized with rigid internal fixation, and if it occurs, how long it lasts. In 10 consecutive patients operated with bilateral sagittal split osteotomies, postoperative migration, defined as displacement of the proximal segments in relation to ...
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...
