treatment planning poses difficulties in edentulous patients for orthognathic surgery prediction and fixation.treatment of severe class iii malocclusion frequently requires orthognathic surgical procedures. for such patients, orthognathic surgery would be the only option before prosthetic rehabilitation.this clinical report describes step-by-step fabrication of a surgical splint for an edentulo...

For orthodontic diagnosis and treatment planning there are various ways to assess the jaw discrepencies. Using parameters such as ANB, Wit’s appraisal, Beta, Yen, W angles, with some limitations. To overcome these, MKG angle Tau were proposed.
 Aim objective: The present study assesses predictability of its correlation previous parameter. Materials methods: A total 105 lateral cephalograms...

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 ...

The aim of this study was to evaluate the centroid method of occlusion for studying mandibular growth and development. This novel technique comparatively expresses the direction of growth of the maxilla and mandible as a single unit. The centroid 'G' was geometrically calculated from the triangle Deltaabc, which comprised the palatal, articulare-gnathion (Ar-Gn), and A-B planes. The plane angle...

INTRODUCTION The cranial base plays an important role in determining how the mandible and maxilla relate to each other. This study assessed the relationship between the cranial base and jaw base in a Chinese population. METHODS This study involved 83 subjects (male: 27; female: 56; age: 18.4±4.2 SD years) from Hong Kong, who were classified into 3 sagittal discrepancy groups on the basis of t...

Angle Class III malocclusion is characterized by an inadequate anteroposterior dental relationship which may or may not be accompanied by skeletal changes. In general, patients are distressed by a significantly compromised facial aspect which, when associated with a deficient middle third, encourages patients to seek treatment. This article reports a two-phase treatment carried out in a female ...

BACKGROUND Information regarding the prevalence of surgical osteotomies used for the correction of dentofacial deformities in Iran is lacking. MATERIALS AND METHODS This retrospective cross-sectional study assessed the distribution of orthognathic surgeries performed (2011-2015) at major University hospital in Iran. Records of 103 orthognathic surgery patients were assessed (58 female, 45 mal...
