Background: Orthognathic surgery is widely used surgical procedure. The most common orthognathic procedure bilateral sagittal split osteotomy (BSSO) that for managing skeletal mandibular excess, deficiency or asymmetry. Objective: To correct functional and aesthetic problems. Patients Methods: A total of (12 patients) 24 condyles have been included in our study all with cl II malocclusion, open...

PURPOSE Because condylar positioning after sagittal split ramus osteotomy of the mandible has been known to affect postoperative skeletal stability, accurate positional assessment of the temporomandibular joint after orthognathic surgery is vital to maximize stability of the surgery. The purpose of this study was to evaluate condylar changes after single-jaw and double-jaw surgeries in mandibul...

OBJECTIVE The purpose of the present study was to evaluate the postoperative three-dimensional (3D) changes in the proximal segments after mandibular setback sagittal split ramus osteotomy and to compare the changes between the conventional mini-plate fixation and semi-rigid sliding plate fixation. METHODS Cone-beam computed tomography (CBCT) images were used to evaluate the postoperative 3D ...

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...

OBJECTIVE To evaluate whether mandibular setback surgery (MSS) for Class III patients would produce gradients of three-dimensional (3D) soft tissue changes in the vertical and transverse aspects. MATERIALS AND METHODS The samples consisted of 26 Class III patients treated with MSS using bilateral sagittal split ramus osteotomy. Lateral cephalograms and 3D facial scan images were taken before ...

OBJECTIVE To evaluate condylar head remodeling after mandibular set-back sagittal split ramus osteotomy (SSRO) with rigid fixation in skeletal class III deformities. The correlation between condylar head remodeling and condylar axis changes was determined using cone-beam computed tomography (CBCT) superimposition. METHODS The CBCT data of 22 subjects (9 men and 13 women) who had undergone man...
