OBJECTIVE The purpose of this study was to compare the morphologic changes of the upper airway space in Class III patients who underwent mandibular setback or bimaxillary surgery (maxillary advancement and mandibular setback) by computed tomography at 2 levels: soft palate and base of tongue. METHODS The sample consisted of 47 subjects in 2 groups who had been diagnosed as having Class III sk...

BACKGROUND Mandibular setback osteotomies potentially lead to narrowing of the pharyngeal airways, subsequently resulting in post-surgical obstructive sleep apnea (OSA). OBJECTIVE To summarize current evidence from systematic reviews that has evaluated pharyngeal airway changes after mandibular setback with or without concomitant upper jaw osteotomies. METHODOLOGY PubMed, EMBASE, Web of Sci...

Abstract—This study estimates the seismic demands of tall buildings with central symmetric setbacks by using nonlinear time history analysis. Three setback structures, all 60-story high with setback in three levels, are used for evaluation. The effects of irregularities occurred by setback are evaluated by determination of global-drift, story-displacement and story drift. Story-displacement is ...

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 setback with bssro, osteosynthesis wiring and inter maxillary f...
