Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of a Modified Twin-Block Appliance with Clear Plates in treating patients with skeletal Class II malocclusion, characterized by a retracted lower jaw. Participants will be divided into two groups: one receiving the new appliance and the other receiving the traditional Twin-Block Appliance. The study aims to assess changes in skeletal, dental, and soft tissue structures resulting from these interventions. The outcomes will be compared to determine the efficacy of the new treatment approach.
