This study evaluated the morphological changes in the temporomandibular joint (TMJ) condyles and calculated the Helkimo clinical dysfunction index (CDI) in adolescents with Class II Division 1 malocclusion and mandibular retrognathism treated with the Herbst appliance (phase I) and fixed orthodontic appliances (phase II). Thirty-two consecutive adolescents underwent phase I, and 23 completed ph...

The semi-dominant Br mutation affects presphenoid growth, producing the facial retrognathism and globular neurocranial vault that characterize heterozygotes. We analysed the impact of this mutation on skull shape, comparing heterozygotes to wildtype mice, to determine if the effects are skull-wide or confined to the sphenoid region targeted by the mutation. In addition, we examined patterns of ...

Previous research has shown that the position of glenoid fossa differs in different skeletal relationships. However, it is hard to identify and trace the glenoid fossa on a lateral cephalometric radiograph. The aim of the present study was to evaluate the anteroposterior and the vertical positions of the porion point (P) in different skeletal relationships as seen on lateral cephalometric radio...

The aim of this study was to evaluate skeletal, dentoalveolar, and soft tissue profile changes with activator and high-pull headgear combination therapy in patients with Class II malocclusions caused by maxillary prognathism and mandibular retrognathism. The subjects, all in the mixed dentition, were selected from a single centre and were divided into two groups: 28 patients were treated with a...

Introduction: Many authors have discussed the relationship between craniofacial morphology and pharyngeal airway spaces in different malocclusions skeletal patterns. So aim of this work was to study relation sagittal position mandible volume adults using CBCT. Materials And Methods:Twentyone CBCT radiographs were collected from archive Radiology Department at Suez Canal University divided into ...

The purpose of this investigation was to evaluate the efficiency of the FR-3 appliance on functional Cl III malocclusion cases. A total of 45 functional Cl III cases were chosen from a general clinic intake of which 25 were treated with the FR-3 appliance and 20 were untreated and were taken as a control group. Patients that were treated with FR-3 had the following characteristics: Cl III with ...
