Condylar positioning changes following unilateral sagittal split ramus osteotomy in patients with mandibular prognathism
BACKGROUND This study was performed to evaluate three-dimensional positional change of the condyle using three-dimensional computed tomography (3D-CT) following unilateral sagittal split ramus osteotomy (USSRO) in patients with mandibular prognathism. METHODS This study examined two patients exhibiting skeletal class III malocclusion with facial asymmetry who underwent USSRO for a mandibular ...
متن کاملRigid fixation of intraoral vertico-sagittal ramus osteotomy for mandibular prognathism.
The standard surgical treatment for mandibular prognathism is sagittal split ramus osteotomy (SSRO) if the proximal and distal segments of the ramus require fixing with screws or metal plates. In this procedure, however, it is frequently difficult to avoid neurosensory disturbance (NSD) of the inferior alveolar nerve (IAN) when the posterior margin of the ramus curves inward or when the ramus i...
متن کاملChanges in temporomandibular joint and ramus after sagittal split ramus osteotomy in mandibular prognathism patients with and without asymmetry.
The purpose of this study was to examine the changes in the temporomandibular joint (TMJ) and ramus after sagittal split ramus osteotomy (SSRO) with and without Le Fort I osteotomy. The subjects consisted of 87 Japanese patients diagnosed with mandibular prognathism with and without asymmetry. They were divided into 2 groups (42 symmetric patients and 45 asymmetric patients). The TMJ disc tissu...
متن کاملThe sagittal split ramus osteotomy as the preferred treatment for mandibular prognathism.
The SSRO with rigid fixation (RF) can be best applied for correction of mandibular prognathism after the age of 12 years (after eruption of the mandibular second molars) in symmetric and mild to moderate asymmetric cases. Contraindications for the SSRO include 1) presence of unerupted mandibular second molars: 2) a severely narrow anteroposterior or mediolateral dimension of the ramus with no m...
متن کاملSkeletal Relapse after Correction of Mandibular Prognathism by Bilateral Sagittal Split Ramus Osteotomy
Received: 28 August 2008 Accepted: 14 January 2009 Abstract: Objective: The aim of this study was to assess skeletal relapse in patients who underwent mandibular setback by bilateral sagittal split ramus osteotomy (BSSRO) and osteosynthesis wiring techniques. Materials and Methods: In this semi-experimental study, 10 patients (8 women, 2 men) with 3-8 millimeters overjet underwent mandibular se...
