CE Incisor malocclusion is common in rabbits. If this condition occurs as an isolated entity at an early age, it probably has a genetic origin. Incisor malocclusion in older animals is usually secondary to, or occurs concomitantly with, premolar–molar malocclusion. Therefore, patients with incisor malocclusion should always receive a comprehensive oral examination. Incisor–premolar–molar malocc...

To provide quantitative data about the prevalence of malocclusions in the Shiraz orthodontic population, we studied the records of 700 patients (391 girls and 309 boys) aged 6-14 years attending the undergraduate Department of Orthodontics at Shiraz University of Medical Sciences. The prevalence of Angle class I, II and III malocclusion of first molars was 52.0%, 32.6% and 12.3% respectively. S...

This study evaluated the effectiveness of early orthodontic treatment with the Twin-block appliance for the developing Class II Division 1 malocclusion. This multicenter trial was carried out in the United Kingdom. A total of 174 children, aged 8 to 10 years old, with Class II Division 1 malocclusion were randomly allocated to receive treatment with a Twin-block appliance or to an untreated, co...

The orthodontic treatment of class III malocclusion with a maxillary deficiency is often treated with maxillary protraction with or without expansion. Skeletal and dental changes have been documented which have combined for the protraction of the maxilla and the correction of the class III malocclusion. Concerning the ideal time to treat a developing class III malocclusion, studies have reporte...

BACKGROUND A dental survey was conducted among the school going children of age group 6-13 yrs, focused to find out incidence of malocclusion so as to predict the probable time at which preventive measures can be taken. MATERIALS AND METHODS A survey was carried on 985 unrelated healthy subject, including of 575 boys and 410 girls and the population was divided into three economic group of up...

The purpose of this study was to evaluate the prevalence of malocclusion and to assess the need for orthodontic treatment among 6-10 year old Turkish primary school children. The Treatment Priority Index (TPI) was used to record and measure the malocclusions. The findings were that 40.38 per cent of the observed population showed normal occlusion, 21.85 per cent had minor manifestations of malo...

Objective: Mandibular prognathism is inadaptability between skull and mandible and is one phenotype of class III malocculsion. Polydiastema may be present together with class III malocclusion. Skeletal class III malocclusion with mandibular prognathism can be diagnosed by cephalometric parameters. Study Design: A 22-year-old man complaining about difficult mastication and speech was referred to...

The disturbances of orofacial functions lead to abnormal growth and development of the orofacial complex. The aim of the study was to determine the prevalence of incompetent lip seal and respiration disturbance, and to improve the understanding of correlation between incompetent lip seal and morphological malocclusions. In the sample of 84 children (45 girls and 39 boys, aged 8.96 +/- 0.66 year...

classification of occlusion is the first step in diagnosing the relationship between the upper and lower jaw's teeth. based on angle's classification, occlusion is divided into three categories: class i, class ii, and class iii. the aim of this study was to determine the prevalence of occlusion categories, based on angle's classification, in adolescents with permanent dentition in tehran. this ...

an increased overbite may be due to a skeletal or dental etiology that may influence treatment. the purpose of this study was to evaluate the skeletal and dentoalveolar features in patients with deep bite malocclusion in an iranian population and to determine the most and least effective and contributory variables causing deep bite.lateral cephalograms and study casts of normal (n=85) and deep ...
