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...
statement of problem: the gonial angle plays an important role in ensuring a harmonious facial profile. changes in this angle especially after surgery may be an aesthetic concern for both the patient and the surgeon. purpose: the aim of the present study was to evaluate gonial angle changes after mandiblular setback with the bssro technique and to measure postsurgical relapse two years after su...
Sagittal split osteotomy (SSO) is a surgical technique largely employed for mandibular mobilizations in orthognatic procedures. However, the traditional design of buccal osteotomy, located at the junction of mandibular ramus and body, may prevent more extensive sliding between the bone segments, particularly on the advance, laterality and verticality of the mandibular body. The author proposes ...
Abstract Background Medial open-wedge high tibial osteotomy (HTO) is an effective and safe treatment method for medial osteoarthritis of the knee. However, unintended changes in posterior slope (PTS) may occur. Several factors cause PTS alterations after HTO; however, research on sagittal-plane inclination (SPOI) relation to sparse. The purpose this study was evaluate whether SPOI affects HTO. ...
The purpose of this study was to evaluate hypoesthesia of the lower lip using trigeminal somatosensory-evoked potential following 2 types of sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy (IVRO). There were 30 patients with mandibular prognathism, with and without asymmetry, who were divided into three groups: the Obwegeser method (Ob) group, the Obwegeser-Dal Pont...
In oral and maxillofacial surgery, many complications associated with nasotracheal tube can be caused. In this case, we reported ballooning tube damage of nasotracheal tube during orthognathic double-jaw surgery and replacement of tube through cut down of tube and tube exchange using airway exchange catheter. The patient scheduled for high Le Fort I osteotomy and bilateral sagittal split osteot...
Orthognathic surgery is a common approach for treatment of maxillofacial deformi‐ ties. Sagittal split ramus osteotomy (SSRO) is one of the most common techniques used to treat various mandibular deformities. A LeFort I osteotomy is suggested in deformities of the maxilla and can be used along with SSRO or intra‐oral vertical ramus osteotomy (IVRO).The aim of orthognathic surgery is to improve ...
OBJECTIVE This study evaluated the mechanical characteristics and stress distribution of the hybrid technique fixation of the sagittal split ramus osteotomy. STUDY DESIGN In the mechanical test, 10 polyurethane replicas of human hemimandibles of each group were submitted to linear loading test. For the photoelastic evaluation, 3 hemimandible replicas of photoelastic resin were subjected to ph...
