PURPOSE The purpose of this study was to evaluate change in computed tomography (CT) value of condyle and temporomandibular joint (TMJ) disc position after sagittal split ramus osteotomy (SSRO) setback surgery, retrospectively. SUBJECTS AND METHODS The subjects were 76 patients (152 condyles) who underwent bilateral SSRO setback surgery. They were divided(More)
The purpose of this study was to compare computed tomography (CT) Hounsfield unit values of bone fragment gaps after sagittal split ramus osteotomy (SSRO) in patients with and without asymmetry, and to evaluate differences between the deviated and non-deviated sides in asymmetric patients. Thirty-two patients who underwent a bilateral SSRO were included in(More)
PURPOSE The purpose of this study was to examine skeletal stability and plate breakage after sagittal split ramus osteotomy (SSRO) with the mono-cortical plate fixation, bi-cortical plate fixation, and hybrid fixation techniques using absorbable plates and screws. MATERIALS AND METHODS A total of 76 Japanese patients diagnosed with mandibular prognathism(More)
PURPOSE The purpose of this study was to compare bone regenerative capability following use of polytetrafluoroethylene (ePTFE) membrane against that when various densities of pore titanium meshes are used with and without low intensity pulsed ultrasound (LIPUS). MATERIALS AND METHODS Adult male white rabbits were divided into 8 groups. In 4 groups, after(More)
PURPOSE The purpose of this study was to evaluate bony change between the proximal and distal segments after sagittal split ramus osteotomy (SSRO) using different fixation materials. SUBJECTS AND METHODS The subjects consisted of 74 patients (21 male and 53 female; 148 sides) who underwent SSRO with and without Le Fort I osteotomy. They were divided into(More)
PURPOSE The purpose of this study was to evaluate, through cephalometric analysis, the skeletal stability following BSSRO performed with and without extraction of the third molar, and to examine the healing of the extraction sockets through computed tomography (CT). PATIENTS AND METHODS Sixty Japanese patients (male: 14, female: 46) diagnosed with(More)
PURPOSE The purpose of this study was to examine the skeletal stability of mandibular advancement after sagittal split ramus osteotomy (SSRO) with modified hybrid fixation using absorbable plates and screws. MATERIALS AND METHODS A total of 54 Japanese patients were enrolled in this study. Of them, 23 who were diagnosed with mandibular prognathism(More)
The purpose of this study was to evaluate the effects of Le Fort I osteotomy on nasal septum deviation and differences in left and right airway sizes, and to determine whether the nasal septum was affected by differences in the direction of movement. Forty patients underwent conventional Le Fort I osteotomy, and computed tomography (CT) was performed(More)
PURPOSE The purpose of this study was to evaluate changes in mandibular body height at the site of a fixation plate in the advance (lengthening) and setback (shortening) sides after sagittal split ramus osteotomy (SSRO). SUBJECTS AND METHODS The subjects were 49 patients (98 sides) who underwent bilateral SSRO surgery. The subjects were divided into 4(More)
PURPOSE The purpose of this study was to examine lip closing force in Class II and III patients before and after orthognathic surgery. SUBJECT AND METHODS The subjects were 45 patients (15 Class II women, 15 Class III men and 15 Class III women) diagnosed with jaw deformity who underwent sagittal split ramus osteotomy with Le Fort I osteotomy and 30(More)
