Incisor inclination and arch width changes following mandibular setback surgery for correction of mandibular prognathism
Purpose: The aim of this study was to investigate and evaluate the changes of incisor inclination and arch width in the surgical-orthodontic treatment to correct a Class III malocclusion resulting from skeletal mandibular prognathism. Materials and methods: The skeletal mandibular prognathism subjects consisted of 25 males and 20 females (mean age:22.8±4.2years). A lateral cephalogram was taken...
متن کاملRetrospective study on change in pharyngeal airway space and hyoid bone position after mandibular setback surgery
OBJECTIVES The purpose of this study was to evaluate changes in the pharyngeal airway space and hyoid bone position after mandibular setback surgery with bilateral sagittal split ramus osteotomy (BSSRO) and to analyze the correlation between the amount of mandibular setback and the amount of change in pharyngeal airway space or hyoid bone position. MATERIALS AND METHODS From January 2010 to F...
متن کاملThe change of stress distribution on the condyle after mandibular setback surgery.
The rigid-body spring model (RBSM) theory was incorporated into a model as a discrete method for analysing problems of limit, such as the stress distribution on the condyle. The purpose of this study was to evaluate the two-dimensional RBSM for determining stress on the temporomandibular joint (TMJ) in patients after orthognathic surgery. Thirty-two patients (five males and 27 females, mean age...
متن کاملA more accurate method of predicting soft tissue changes after mandibular setback surgery.
PURPOSE To propose a more accurate method to predict the soft tissue changes after orthognathic surgery. PATIENTS AND METHODS The subjects included 69 patients who had undergone surgical correction of Class III mandibular prognathism by mandibular setback. Two multivariate methods of forming prediction equations were examined using 134 predictor and 36 soft tissue response variables: the ordi...
متن کاملRetrospective study of changes in pharyngeal airway space and position of hyoid bone after mandibular setback surgery by cephalometric analysis
BACKGROUND The posterior movement of mandible was known as the main cause of the changes in the pharyngeal airway space (PAS) and the postoperative obstructive sleep apnea (OSA). The purpose of this study was to know the changes of PAS and position of hyoid bone. METHODS Lateral cephalographies of 13 patients who had undergone sagittal split ramus osteotomy (SSRO) setback surgery were taken p...
