The Use of an Esthetic Twin Block for Patients With Mandibular Retrusion

This experimental study will evaluate the effect of an esthetic Twin-block appliance on the correction of class II malocclusion compared with the traditional Twin-block appliance. The study sample will consist of 50 patients with class II malocclusion. The sample will be allocated randomly into two groups: the control group and the experimental group. The traditional Twin-block appliance will be applied for the control group patients, while the esthetic Twin-block appliance will be applied for the experimental group patients. The dentoskeletal, soft tissue changes and esthetic and functional efficacy occurring after functional treatment will be assessed using cephalometric radiographs and profile photographs, pre and post-treatment, and a questionnaire. Changes for each group will be evaluated individually, and the two groups will be compared.
