Evaluation of the Effect of Corticotomy and Low Level Laser Therapy on Orthodontic Tooth Movement

Not Applicable

Completed

• Conditions: Dental Malocclusion
• Interventions: Procedure: Corticotomy and low laser therapy; Procedure: Corticotomy facilitated Orthodontics

• Registration Number: NCT03906084
• Lead Sponsor: Cairo University

Brief Summary

The aim of the present study was to compare, a standard efficient technique in accelerating OTM as surgical corticotomy as a gold standard versus surgical corticotomy combined with LLLT in an attempt for further acceleration of OTM.

Detailed Description

The study design was a randomized split mouth design to compare, clinically and radiographically, between the two interventions (Corticotomy and Laser versus Corticotomy only) by assessing the rate of maxillary canine retraction achieved in 4 months. Secondary outcomes were to evaluate 1st maxillary molar anchorage loss, changes in tipping, torque and rotations values of maxillary canine and 1st molar. In addition, the impact of both interventions on root resorption was assessed. The present study was carried on 16 female patients. All patients required maxillary 1st premolar extraction and subsequent maxillary canine retraction.

Arm && Interventions

Group	Intervention	Description
Corticotomy facilitated orthodontics.	Corticotomy and low laser therapy	Corticotomy is carried out under local anesthesia in right side.
