BACKGROUND The aims of this study are to evaluate the lip morphology and change of lip commissure after mandibular setback surgery (MSS) for class III patients and analyze association between the amount of mandibular setback and change of lip morphology. METHODS The samples consisted of 14 class III patients treated with MSS using bilateral sagittal split ramus osteotomy. Lateral cephalogram ...

OBJECTIVES The aim of this study was to determine the validity of a manual cephalometric method used for predicting the post-operative soft tissue profiles of patients who underwent mandibular setback surgery and compare it to a computerized cephalometric prediction method (Dentofacial Planner). Lateral cephalograms of 18 adults with mandibular prognathism taken at the end of pre-surgical ortho...

Purpose: The purpose of this study was to assess skeletal stability after mandibular setback surgery with and without an inter-maxillary fixation (IMF) screw. Subjects and Methods: The subjects consisted of 40 patients with mandibular prognathism. The subjects underwent sagittal split ramus osteotomy (SSRO) with titanium plate fixation and were divided into two groups, one with and one without ...

Setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. This paper addresses multistory Reinforced Concrete (RC) frame buildings, regular and irregular in elevation. Several multistory Reinforced Concrete Moment Resisting Frames (RCMRFs) with different types of setbacks, as well as the regular frames in elevation, are designed according...

Background: The aim of this study was to examine whether the thickness preoperative soft tissue affects degree movement relative hard after orthognathic surgery. Methods: This is a retrospective examination lateral cephalometric X-rays patients who underwent surgery in single medical center, during 5-year period. Demographic and operative data were collected. Soft measured X-ray, followed by su...

The objective of this research was to study the impact of skeletal Class III malocclusion on patients' emotional status, as well as patients' motivations for seeking surgical correction of Class III malocclusion. The sample comprised 140 consecutive Chinese patients with skeletal Class III malocclusion who had been treated with a combined orthodontic-surgical approach. A retrospective analysis ...

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...
