Effects of Clear Aligners Versus Fixed Appliances on Occlusion After Treatment of Mild Anterior Crowding

Not Applicable

• Conditions: Occlusion
• Interventions: Device: Clear aligners; Device: Fixed appliances

• Registration Number: NCT05737290
• Lead Sponsor: Al-Azhar University

Brief Summary

The aim of this study is to evaluate effects of clear aligners versus fixed appliances on occlusion after treatment of mild anterior crowding a T-scan study.

Detailed Description

Intervention:

Group 1. Patients treated with clear aligner. Patients with mild anterior crowding will be treated with non-extraction treatment using clear aligners.

Group 2. Patients treated with fixed appliance. Patients with mild anterior crowding will be treated with non-extraction treatment using fixed appliances.

Observations:

Multi-bite closure of left and right excursive T-Scan® recordings were obtained before and after treatment from each subject to measure the occlusal parameters to be analyzed during this study.
