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...
Clinical entity with several treatment options. Treatment of these cases requires extremely well-coordinated orthodontic and surgical treatment planning and execution. This is a case report of 30 year old female adult patient who presented with skeletal class II malocclusion with excessive vertical growth of maxilla. Vertical maxillary excess, thin alveolar troughs, proclined upper and lower an...
In this study, a survey was conducted on the occurrence of skeletal malocclusions presented by patients of the Center for Research and Treatment of Buccofacial Deformities (CEDEFACE) in the city of Araraquara, SP, Brazil. The clinical charts of 381 patients with dentoskeletal deformities, who underwent combined orthodontic-surgical treatment in the period between 2000 and 2006, were reviewed. A...
Angle, Tweed, and Moyers classified Class III malocclusions into 3 types: pseudo, dentoalveolar, and skeletal. Clinicians have been trying to identify the best timing to intercept a Class III malocclusion that develops as early as the deciduous dentition. With microimplants as skeletal anchorage, orthopedic growth modification became more effective, and it also increased the scope of camouflage...
INTRODUCTION In this study, we aimed to compare treatment efficacy and postsurgical stability between minimal presurgical orthodontics and conventional presurgical orthodontics for patients with skeletal Class III malocclusion. METHODS Forty patients received minimal presurgical orthodontics (n = 20) or conventional presurgical orthodontics (n = 20). Lateral cephalograms were obtained before ...
Diagnosis A 12-year-old male in the late mixed dentition was referred by his dentist for orthodontic treatment. Initial examination revealed a skeletal and dental Class II malocclusion with a retrognathic mandible, a severe overbite, moderate overjet, and mild malalignment of both arches, including rotations and generalized spaces in the mandibular arch (Fig. 1). The facial type was hypodiverge...
Class III malocclusion associated with skeletal anterior open bite pattern in adults can be a challenging orthodontic problem, especially for the nonsurgical treatment. Conventionally, several treatment alternatives are available such as tooth extraction, molar intrusion, and absolute anchorage system or orthognathic surgical correction. Although correction with surgery may be the most effectiv...
The aim of the present work was to determine the duration of the adolescent peak growth spurt using cervical vertebral maturation analysis in class I and II malocclusion subjects. The study was conducted on a sample which consisted of 154 lateral cephalograms of children and adolescents aged 9-15 years (84 females and 70 males). The evaluation of skeletal maturation stage was performed using a ...
Anterior open bite (AOB) is a very common malocclusion in the orthodontic practice. The management of this malocclusion is not easy because of its multifactorial etiology; indeed, there are many factors which determines its etiology: oral habits, alterated labial postures, tongue habits and a vertical facial growth pattern. The aim of this study was to analyze clinical features and the differen...
