INTRODUCTION The objectives of this research were to assess skeletal and dental changes in patients with Class II malocclusion treated with the edgewise crowned Herbst appliance in the early mixed dentition and to measure the stability of treatment after a second phase of fixed appliance therapy. METHODS Twenty-two patients (ages, 8.4 ± 1.0 years) with Class II Division 1 malocclusion treated...

We describe the treatment of a young adult male (aged 14 years 9 months) with Class III malocclusion using a mini maxillary protraction appliance, and discuss the results. The patient was treated with an acrylic cap splint-type expander and a modified maxillary protractor until a positive overjet was achieved. Edgewise fixed appliances were used to align the teeth. The treatment resulted in Cla...

ABSTRACT The purpose of this study was to analyze the overjet and overbite behavior during eruption of the upper permanent incisors. Fourth-eight plaster casts of 16 patients from ages 6-13 years were appraised longitudinally. It was found that the overjet remains constant, starting at the eruption of the upper permanent central incisors until eruption of the upper permanent canine teeth, while...

Introduction Class II malocclusions are commonly associated with some muscle disharmony and imbalance. Diagnosis of imbalance helps in treating the malocclusion as well preventing relapse treatment. The aim this study is to compare activity masseter temporalis patients skeletal division 1 varying overjet using surface electromyography (sEMG). Materials methods Ten subjects age range 18-35 years...

Occlusal characteristics and anomalies were studied among 869 (428 boys, 441 girls) Tanzanian Bantu children aged 3.5-16 years and 706 (319 boys, 387 girls) Finnish children aged 5-11 years during different emergence stages of the permanent dentition. Various occlusal variables were registered according to described criteria. Multiple linear regression, ANOVA, t-test, Chi-square and logistic re...

BACKGROUND Aim of this prospective study was to determine prevalence of malocclusion and associated risk factors in 3-year-old Thuringian children. METHODS Subjects (n = 377) were participants in a regional oral health programme, a birth cohort study with the aim to prevent caries (German Clinical Trials Register DRKS00003438). Children received continuous dental care since birth. Occlusal ch...
