Biomechanical Loading Evaluation of Unsintered Hydroxyapatite/poly-l-lactide Plate System in Bilateral Sagittal Split Ramus Osteotomy
OSTEOTRANS MX® (Takiron Co., Ltd., Osaka, Japan) is a bioactive resorbable maxillofacial osteosynthetic material composed of an unsintered hydroxyapatite/poly-l-lactide composite, and its effective osteoconductive capacity has been previously documented. However, the mechanical strength of this plate system is unclear. Thus, the aim of this in vitro study was to assess its tensile and shear str...
متن کاملEvaluation of bone formation after sagittal split ramus osteotomy with bent plate fixation using computed tomography.
PURPOSE To evaluate bone formation between the proximal and distal segments after a sagittal split ramus osteotomy (SSRO) with bent plate fixation. PATIENTS AND METHODS The subjects were 23 patients (46 sides) who underwent bilateral SSRO setback surgery. They were divided into titanium and absorbable plate groups. A 3 to 7-mm gap was made between the proximal and distal segments and a bent p...
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 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...
