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

Sponsor

Hama University

Enrollment

24 participants

Start Date

Aug 25, 2026

Study Type

INTERVENTIONAL

Conditions

Class II Malocclusion Malocclusion

Summary

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.

Interventions

DEVICEclear aligners

clear aligners will be applied to the upper and lower arch, then a class II elastics 1\\4 and 6,5 oz will be use from the precision-cut Hook on the maxillary aligner to the button of mandibular first molar

DEVICEtraditional treatment Fixed appliances with class II elastics.

Agroup of patients in which participants will be undergo to the fixed multibracket treatment (with slot size 0.022 × 0.028 and MBT prescription , after completing leveling and alignment , Elastics will be applied from the hooks of canines brackets to the hooks of lower first molar when the 0.019× 0.025-inch stainless steel archwires placed.
