Class III malocclusion is one of the most common deformities that requires correction through orthodontic-surgical treatment. These patients present different facial patterns depending on the occlusal plane angulation. These patients may benefit from surgical manipulation of the occlusal plane, because only bite correction does not always lead to the improvement of the facial deformity. The pur...

Pseudo-Class III malocclusion is characterized by the presence of an anterior crossbite due to a forward functional displacement of the mandible; in most cases, the maxillary incisors present some degree of retroclination, and the mandibular incisors are proclined. Various types of appliances have been described in the literature for the early treatment of pseudo-Class III malocclusion. The obj...

the facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient's natural head position. the purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion.our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class i (n=32), class ii (n=40) and class iii (n=30). nin...

BACKGROUND AND AIMS Class III malocclusions are considered as one of the most complex orthodontic problems to diagnose and treat. Numerous studies have been conducted to determine the morphologic characteristics of craniofacial complex in patients with this malocclusion. The aim of this study was to determine the dentofacial characteristics of Class III malocclusion in Mashhadian adults. MATE...

OBJECTIVE To determine the prevalence of tooth size discrepancies (TSDs) in an Irish orthodontic population among different malocclusion groups. MATERIALS AND METHODS From 850 pretreatment sets of orthodontic models at a university clinic, 240 were selected with 30 female and 30 male sets for each malocclusion (Class I, Class II division 1, Class II division 2, and Class III). Digital models ...

The purpose of this study was to investigate the changes of craniofacial morphology and tongue position in children with Class III malocclusion after tongue myofunctional exercises (TME). TME were applied to 25 patients with class III malocclusion for 1.01 ± 0.02 years. Lateral cephalograms were taken and cephalometric analysis was evaluated. Compared with the control group, facial angle, S-Ti ...

PURPOSE The purpose of this study was to compare asymmetric mandibular prognathism individuals with symmetric mandibular prognathism individuals using a new alternate spherical coordinate system. MATERIALS AND METHODS This study consisted of 47 computed tomographic images of patients with mandibular prognathism. The patients were classified into symmetric and asymmetric groups. Mandibular and...

BACKGROUND The orofacial musculature plays a pivotal role in maintaining a balance in positioning of the teeth and any imbalance which occurs in this , results in malocclusion. Lingual frenum is a soft tissue structure which tethers the ventral surface of the tongue to the floor of the mouth. OBJECTIVE This study was performed to analyze the lingual frenal lengths in skeletal class I, class I...
