T individuals rendered edentulous and provided with complete dentures display marked changes in jaw relations due to resorption of the residual alveolar ridges. The changes are characterized by an upward rotation of the mandible with a resulting decrease in occlusal vertical dimension and increase in mandibular prognathism. I-3 The most rapid changes occur during the first year, when the rate o...

facial deficiency or true mandibular prognathism are difficult to manage nonsurgically, particularly when a hyperdivergent mandibular growth pattern creates an anterior open bite. For the past 25 years, early growth modification of midfacial deficiency with expansion and facemask therapy has been the standard treatment for Class III malocclusions.1,2 A disadvantage of this ap proach is that it ...

PURPOSE To analyze the relative position of the mandibular foramina (MnFs) in patients diagnosed with skeletal class III malocclusion. MATERIALS AND METHODS Computed tomography (CT) images were collected from 85 patients. The vertical lengths of each anatomic point from the five horizontal planes passing through the MnF were measured at the coronoid process, sigmoid notch, condyle, and the go...

Background: Thalassaemia is the single most common gene disorder in the world and represents major health burden. The most common oral and craniofacial manifestations are enlargement of maxilla, bossing of the skull and prominent malar eminences. The aim of the study was to assess the radiological changes of the oral and craniofacial region in β thalassaemic children with in the age group of 12...

INTRODUCTION It has been suggested that mandibular setback surgery, combined or not with maxillary advancement as a treatment alternative for patients with mandibular prognathism, can induce changes in upper airway space (UAS). Therefore, this study aimed to assess the response of the upper airway in the oropharynx region of patients with Class III skeletal pattern that underwent bimaxillary or...

A 25-years-old woman with mandibular prognathism underwent a mandibular setback by way of mandibular sagittal split ramus osteotomy (MSSRO). After 2 days of operation, she developed difficulty of closing her right eye. The blink reflex test and motor nerve conduction study of the right orbicularis oris muscle were revealed right facial neuropathy of unknown origin and House-Brackmann facial ner...

OBJECTIVE To compare the effectiveness of the rapid maxillary expander and facemask (RME/ FM) and mandibular cervical headgear (MCH) protocols when followed by fixed appliances and evaluated at a postpubertal observation in patients with dentoskeletal Class III malocclusion. MATERIALS AND METHODS The sample treated with the RME/FM followed by fixed appliances included 32 patients (12 boys and...
