Comparison of Activator-Headgear and Twin Block Treatment Approaches in Class II Division 1 Malocclusion
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...
متن کاملTreatment effects of the R-appliance and twin block in Class II division 1 malocclusion.
The purpose of this study was to compare the effects of a differently designed functional appliance (the R-appliance) with a twin-block (TB)-treated group. Thirty patients (18 girls and 12 boys) with a mean age of 10.5±0.7 years were treated with the R-appliance for 16.2±0.3 months and 25 (11 boys and 14 girls) with a mean age of 11.2±1.3 years with a TB for 16.1±1.4 months (control). All had a...

Background and Aim: The aim of the present study was to evaluate the cephalometric changes in Class II division 1 mandibular deficient patients treated with Farmand functional appliance. Methods and Materials: Twenty-seven subjects (17 girls and 10 boys) with the mean age of 11.1±1.4 years were involved in the present study. All the subjects were treated with Farmand functional ...
متن کاملBimaxillary morphometry of patients with class II division 1 malocclusion treated with twin block appliances.
To assess changes in bimaxillary morphology in patients with Class II division I malocclusion treated using Twin Block appliances (TBA), pre- and posttreatment lateral cephalographs of 100 patients seven to 16 years of age were compared. The patients were divided into four groups: (1) prepubertal boys (mean treatment time; 13.6+/-4.0 months), (2) adolescent boys (20.1+/-7.7 months), (3) prepube...
