Since the occurance of malocclusion very in different races, figures offerred by the foreign researchers may not generalized to be Iranian society. By this research, multiple steps random sampling was applied...

OBJECTIVES We evaluated the skeletal and dentoalveolar effects of the Forsus Fatigue Resistance Device (FRD) and the Twin Block appliance (TB) in comparison with nontreated controls in the treatment of patients with class II division 1 malocclusion. MATERIALS AND METHODS THIS RETROSPECTIVE STUDY INCLUDED THREE GROUPS: TB (n=37; mean age, 11.2 years), FRD (n=30; mean age, 12.9 years), and cont...

OBJECTIVE To compare the skeletal changes between female hyperdivergent adolescents and adults with Class II Division 1 malocclusion after orthodontic treatment. METHODS Thirty adolescent girls and 30 adult women both with hyperdivergent Class II Division 1 malocclusions were selected. The 2 groups were matched by both treatment period and treatment method. Cephalometric radiographs taken bef...

Background: The Class II Malocclusion is the most frequent dento-skeletal anomaly that involves one third of all orthodontic patients.
