No results posted yet for this study

Summary

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

Conditions

  • Malocclusion, Angle Class II
  • Retrognathism
  • TMJ

Interventions

DEVICE

Activator

This appliance is constructed in one piece to guide the position of the mandible on closure

DEVICE

Twin Block

This appliance is constructed in two pieces to guide the position of the mandible on closure
