In this report, we describe an unusual case of chondrosarcoma that involved the entire bimaxillary and nasal skeleton. The pathogenesis, correlation of histopathology with radiology, and management of chondrosarcoma are reviewed.

INTRODUCTION The purpose of this study was to differentiate the dentoalveolar and skeletal effects to better understand orthodontic treatment. We evaluated the treatment changes associated with the bionator and the removable headgear splint (RHS). METHODS The sample comprised 51 consecutively treated Class II patients from 1 office who had all been successfully treated with either a bionator ...

The present study aims to determine differences in vertical facial dimensions as a result of dental wear. The study consisted of 20 subjects with vertical tooth wear. The mean age of sample was 52.4 years. The control group consisted of 20 dental school students. The mean age of control group was 22 years (subjects with severe malocclusion or tooth wear were not included). All subjects’ cephalo...

OBJECTIVE To determine the dentoalveolar heights (mm) in skeletal class I normodivergent facial pattern and compare the same heights in male and female subjects. STUDY DESIGN Cross-sectional observational study. PLACE AND DURATION OF STUDY Orthodontics Clinic, The Aga Khan University Hospital, Karachi, from July to October 2009. METHODOLOGY Eighty one subjects were selected from the ortho...

Objective: Adaptation of the pharyngeal airway space does occur after different surgical strategies of class III patients including mandibular setback, maxillary advancement and bimaxillary surgery. The aim of this study is to conduct a detailed cephalometric evaluation of the alterations taking place in the morphology of the pharyngeal airway space after treatment of class III skeletal deformi...

European-American norms are still used in the orthodontic treatment of Saudi patients, despite the different ethnic backgrounds of Saudis. The aims of this study were to evaluate the cephalometric features of a Saudi population and to establish cephalometric norms for Saudis living in the western region of Saudi Arabia. Seventy lateral cephalometric radiographs of Saudis (32 females and 38 male...

The purpose of this study was to evaluate the craniofacial and occlusal characteristics of the inhabitants in China. The material consisted of cephalograms, pantomograms, dental casts and anthropological measurements taken from 517 inhabitants: 416 Han Chinese in Beijing, Shanghai, Guangzhou and Changchun and 101 Mongolians in Hohhot. The data were compared among the above five regions and also...

Much of the orthodontic treatment undertaken throughout the world, and particularly in the United States, is aimed at correcting dentoalveolar and skeletal malrelationships. With the current level of fixed appliance refinement, we have become quite adept at achieving excellent occlusions. However we often do not consider one important fact when designing our treatment regime: the craniofacial c...

Surgical maxillary repositioning in individuals with vertical maxillary deficiency may be accompanied by skeletal instability. Long-term skeletal changes in 13 patients who underwent a Le Fort I downsliding osteotomy were studied retrospectively. Nine patients underwent a single-jaw procedure, and 4 patients underwent a bimaxillary procedure. Rigid fixation was used in 10 patients, and wire ost...
