Study Overview
Brief Summary
Effects of modified fixed twin block versus removable twin block on skeletal class 2 growing patients with mandibular deficiency:
A Randomized Clinical Trial
Detailed Description
The main objective of the study is to evaluate the effects of the modified fixed TB on class 2 growing cases and to compare its effect to the conventional removable TB
Research question Does the modified fixed twin block have the same effects as removable twin block during treatment of skeletal class 2 growing patients with mandibular deficiency?

Arms & Interventions
Removable twin block group
participants would receive conventional removable twin block for correction of class II malocclusion for 9 months
Intervention: removable twin block (Device)
Fixed twin block group
participants would receive a modified fixed twin block for correction of class II malocclusion for 9 months
Intervention: modified Fixed twinblock (Device)
Outcomes
Primary Outcomes
Over jet reduction
