OBJECTIVE To determine if there was a difference in hard and soft tissue between northern Chinese and northern Indian adolescents with Angle Class II division 1 malocclusion. METHOD A total of 40 Angle Class II division 1 patients, including 20 boys and 20 girls aged 10 to 13 years with no prior treatment, were selected from northern China and northern India, respectively. Overall, 80 cephalo...

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 was to compare the treatment effects of functional appliances activator-headgear (AH) and Twin Block (TB) on skeletal, dental, and soft-tissue structures in class II division 1 malocclusion with normal growth changes in untreated subjects. The sample included 50 subjects (56% females) aged 8-13 years with class II division 1 malocclusion treated with either AH (n = 25) or TB (n = 25...

A study was undertaken to determine the prevalence of malocclusion in Jaipur city, India. A total of 700 subjects, in the age group of 16-26 years were divided into five groups of normal occlusion, Angle's Class I, Class II Div 1, Class II Div 2 and Class III malocclusion. The results revealed that the prevalence of malocclusion was 66.3%, with the majority of them having Class I malocclusion (...

Abstract: Introduction: The increased overjet in Class II Division 1 malocclusion subjects may be due to hyperdivergent growth pattern or Bolton’s tooth size discrepancy. The aim of this investigation was to find the rational factor for overjet in Class II Division 1 malocclusion as growth pattern or Bolton's discrepancy in these subjects. Methods: 120 untreated Class II Division 1 cases who re...

PURPOSE The objective of this study was to assess gonial angle under the angle classification by comparing panoramic radiograph and lateral cephalometric radiograph. MATERIALS AND METHODS 49 patients (25 males, 24 females) with an age range of 12-29 years participated in the present study. Subjects were retrospectively selected among those categorised as skeletal and dental Class I, II, and I...

In this review of literature we are discussing growth modification in treating classII malocclusions. The prevalence of class II malocclusion is very high ranging from 15% to 20%, in some regions in the world it is considered the most common malocclusion, others consider it as the second common malocclusion. It is estimated that one fourth of all patients, and one third of all children, are tre...

OBJECTIVE Mandibular Class II malocclusions seem to interfere in upper airways measurements. The aim of this study was to assess the upper airways measurements of patients with skeletal Class II malocclusion in order to investigate the association between these measurements and the position and length of the mandible as well as mandibular growth trend, comparing the Class II group with a Class ...

The effect of the Jasper Jumper in the treatment of Class II, division 1 malocclusions was studied in 26 consecutive 13-25-year-old patients. The median treatment time was 5 months, followed by a median period of observation or retention of 7 months. The effects of the treatment were evaluated from cephalograms taken before the treatment, at the removal of the Jumpers and at the end of the peri...

Introduction: The inclination of the occlusal plane (OP) is related to type of dental occlusion. The aim of this study was to evaluate and compare the inclination of occlusal plane in Class II patients treated with the upper first premolars extraction or non-extraction modalities. Materials & Methods: Totally, forty 16-25-year-old patients (15 males and 25 females) with class II malocclusion, ...
