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

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.
