Efficiency of Piezo-Corticision in Accelerating Orthodontic Tooth Movement

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to provide evidence on the effectiveness, the efficiency and efficacy of Peizo-Corticission in accelerating orthodontic tooth movement and reducing orthodontic treatment time.

Detailed Description
-----------------
1 Aim of the study- Part I: This prospective controlled clinical trial (CCT), Split Mouth Design is conducted to assess the efficiency of piezo-corticision in accelerating tooth movement and in reducing treatment time during retraction of canine teeth in class II div 1 subjects. Specific aim- Part I: A- To compare rate of tooth retraction between piezo-corticised and the conventionally orthodontically moved canines B- To compare length of treatment of both approaches. 2- Objectives of the Study Part II: This prospective randomized controlled clinical trial (RCT) is designed to assess the efficiency of piezo-corticision in accelerating tooth movement and in reducing treatment time during retraction of anterior teeth in class II div 1 and class 1 bi-maxillary protrusive subjects. Specific aim Part II: To compare rate of tooth retraction between piezo-corticised and the conventionally orthodontically moved incisors To compare length of treatment of both approaches. To evaluate the quality of treatment outcome of both treatment approaches according to American Board of Orthodontics (ABO) standards.
