Effect of a self-ligating bracket system combined with corticision on the rate of orthodontic tooth movement: A controlled clinical trial.

Abstract

Background: The self-ligating bracket system and corticision are two methods for acceleration of orthodontic tooth movement (OTM).

Objectives: The current study aimed to assess the effect of a self-ligating bracket system combined with corticision on the rate of OTM.

Patients and methods: The present study was conducted on 16 female patients divided into two groups: an experimental group of eight patients treated by self-ligating bracket systems used as fixed orthodontic appliances combined with a corticision as a minimally invasive surgical technique for accelerating OTM, and a control group of eight patients treated only by self-ligating bracket systems used as fixed orthodontic appliances. The primary outcome was the percentage of change in Little's Index of Irregularity (LII). The secondary outcome was the time taken to finish the leveling and alignment stage.

Results: In a comparison of the percentage of change in LII for the upper arch between the two groups, the experimental group recorded values that were significantly greater than those recorded in the control group at all time intervals T0-T7, except for T8-T10, which were similar. Both groups recorded (100 ± 0%), with no significant difference between groups (P = 1).

Conclusion: The combination of two methods for acceleration of OTM, a self-ligating bracket system combined with corticision, accelerates the rate of OTM more than in the case of using a self-ligating bracket system only.
