Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. to evaluate the remodeling effects that would take place in the bone structures of the temporomandibular joint (TMJ) during functional treatment.
2. to evaluate the possible change that may occur in mandibular movements following functional treatment.
3. to evaluate the possible change in the spatial relationship between centric occlusion (CO) and centric relation (CR) following functional treatment

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Activator
Patients will be treated using the Activator appliance for one and a half year
Activator
This appliance is constructed in one piece to guide the position of the mandible on closure
Twin Block
Patients will be treated using the Twin Block appliance for 18 months on average
Twin Block
This appliance is constructed in two pieces to guide the position of the mandible on closure
Control
Patients will be monitored until the last assessment times in the other groups. This group will serve as a control group
