NCT ID: NCT03645343 Completed - Clinical trials for Malocclusion, Angle Class II

The Effect of Functional Treatment of Patients With Backward Positioned Chins on the Jaw Joint and Movements

Start date: June 15, 2018
Phase: N/A
Study type: Interventional

Patients with class II malocclusion and retrognathic mandibles will be treated using functional appliances and asses the remodeling that is expected to occur in the temporomandibular joint (TMJ) using cone-beam computed tomography (CBCT) images and we will register mandibular movements using electronic axiograph ( a specific apparatus used to record jaw movements in three dimensions). There are three groups : 1. Activator Group 2. Twin block Group 3. Control Group with no treatment. Patients will be allocated to the three groups randomly. Data will be collected using three different approaches: - CBCT images before treatment and 12 months after treatment - Axiograph registrations before treatment and 12 months after treatment
