Investigating the effect of age on skeletal stability after sagittal split ramus osteotomy for mandibular setback
J Korean Assoc Oral Maxillofac Surg 2012;38:354-9) Objectives: The purpose of this study was to investigate whether the age factor would be related with stability of mandibular setback surgery for patients with mandibular prognathism. Materials and Methods: We compared the relapse patterns of 47 patients divided into three age groups (termed younger, adult, and older). The younger group consist...
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...
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 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 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...
