Treatment of Mild Class II Malocclusion in Adult Patients With Clear Aligners Versus Fixed Multibracket Therapy

Evaluation of Efficacy of Clear Aligners in Correction of Class II Malocclusion Using Intermaxillary Elastics: A Randomized Controlled

Patient with class ii division 1 malocclusion who have mild increased overjet will be treated in this study. The efficacy of clear aligners in the treatment of Class II division 1 Malocclusion Using Intermaxillary Elastics will be assessed. The skeletal, dental and soft tissues changes resulted by this intervention will be studied and compared with the results of Traditional treatment with fixed appliances.

There are two group:

1. a group of patients in which participants will be undergo to the clear aligners with class ii elastics.
2. a group of patients in which participants will be undergo to the traditional fixed appliances with class ii elastics.
