The aim of this cross-sectional study was to determine the prevalence of malocclusions, occlusal traits, and their gender distribution in urban Iranian school children. Five hundred and two subjects (253 females and 249 males, aged 11-14 years) were examined. Molar relationship, overjet (OJ), overbite, midline deviation, crossbite, and crowding/spacing were recorded. Gender dimorphism was evalu...

Abstract A notable proportion of class II population suffer from excessive vertical maxillary growth which leads to subsequent backward rotation of mandible. Excessive tooth show at rest and on smile are the associated presentation of this group.we report  treatment results of this subdivision of class II patients, treated by high pull headgears attached to maxillary acrylic splints with po...

The aim of this study was to investigate the effects of the vertical chincap on mandibular morphology and also on the dentoalveolar structures in patients with high-angle open-bite malocclusions. We examined 35 children with high-angle skeletal Class I or II open-bite malocclusions. Eighteen subjects were selected as the treatment group, and 17 were the controls. Vertical chincaps, applying 400...

This article reports the orthodontic treatment of a patient with skeletal mandibular retrusion and an anterior open bite due to temporomandibular joint osteoarthritis (TMJ-OA) using miniscrew anchorage. A 46-year-old woman had a Class II malocclusion with a retropositioned mandible. Her overjet and overbite were 7.0 mm and -1.6 mm, respectively. She had limited mouth opening, TMJ sounds, and pa...

This study evaluated cephalometric differences between 113 Japanese (43 males and 70 females, aged 14.1 ± 5 years) and 106 European subjects (36 males and 70 females, aged 13.5 ± 7.3 years) using two compound angular measurements and their single components: the overbite depth indicator (ODI) for the assessment of vertical skeletal relationships and the antero-posterior dysplasia indicator (APD...

The prevalence of malocclusion was studied on the Hvar island, Croatia. This island is characterized by high rates of endogamy, inbreeding and reproductive isolation. The sample for this study comprised 224 children, 126 males and 98 females from all schools on the island of Hvar (20.2 per cent of the total public school population). The sample was selected according to age, sex distribution, a...

The first attempt at stimulating growth of the mandible in therapy of distal bite Class II/1 was initiated by Kingsley in 1877. The method described as “jumping the bite” is still applied today according to the principle of functional bimaxillary appliances such as for example activator, bionator, function regulator (1-3) and others, whereby the mandible is brought into the anterior position by...

The stomatographic system has been studied by several researchers, yet it is still unclear, weather a genetically determined facial morphology decides the strength of masticatory muscles,(1) or weather a strong musculature influences the form of the face. This formed the basis of present study to relate muscle activity with various malocclusions. Thus, 60 samples of younger age group were divid...
