Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Bionator
The modified Bionator was used to correct the open bite malocclusion.
Patients were asked to wear the appliance every day.
|
This is a functional appliance that is used to overcome the functional problems and to correct the open bite deformity
|
Active Comparator: Removable Appliance with Posterior Bite Planes
A removable appliance with poster bite planes was used to correct the open bite malocclusion.
Patients were asked to wear this appliance full time expect eating times.
|
This is a one-jaw appliance that is used in conjunction with a tongue crib to control the faulty positions of the tongue and to help in closing the open bite through the use of posterior bite planes.
