Clinical Trial Summary

The aim of this study is to compare to different protocols to treat Class II malocclusion in growing subjects using the twin block appliance

Clinical Trial Description

• Patients will be clinically and radio-graphically examined for eligibility

• Eligible patients will be randomly assigned to one of two groups:

• Control Group: Twin Block Appliance fabricated to Maximum Bite Advancement group

• Intervention Group: Twin Block Appliance fabricated for Incremental Bite Advancement group

• Records will be taken and impressions will be made and poured. In the control group, bite registration will be made with maximum mandibular advancement. In the intervention group, bite registration is made to habitual bite to make a modified twin block.

• Patients will be recalled every 6 weeks for 8 months for monitoring and reactivation of the appliance. ;
