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 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 کاملComplications of Bilateral Sagittal Split Osteotomy in Patients with Mandibular Prognathism
Introduction: Bilateral sagittal split osteotomy (BSSO) of mandible is vastly used in treatment of mandibular deficiencies and discrepancies. Since this method could affect esthetic as well as function, evaluating these effects from various aspects is crucial. This study assessed the effects of this technique on the function of masseter muscle, jaw movements, and sensory changes along with fail...
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 کاملDental and skeletal changes following sagittal split osteotomy for correction of mandibular prognathism.
Skeletal and dental changes were examined in 15 patients presenting with a Class III malocclusion treated by a sagittal split osteotomy. All patients received orthodontic treatment with Straightwire appliances both prior to and following surgery. These appliances were also used for fixation. The lower incisors were proclined by 8.4 degrees before surgery with little change in upper incisor incl...
