The Experimental Research On Rapid Orthodontic Tooth Movement Aided By Alveolar Surgery

By traditional technique, the general rate of orthodontic tooth movement was 1mm/month. Therefore, the process of orthodontic treatment was usually about 2 years or longer. Such a long treatment period may become a social handicap for some patients, especially adult patients. Moreover, it may increase the risk of cariers, periodontal disease and make patients more difficult to cooperate. How to move the teeth safely and quickly is of great concern for the orthodontist. Because of these, scholars all over the world focused how to accelerate the tooth movement and shorten treatment period. Recently, they proposed some new methods to accelerate the tooth movement, such as reducing resistance of periodontal tissue; local stimulation by electromagnetic force and using medications etc. Although these methods did improve the speed of tooth movement, most of them had some disadvantage or were still in the experimental stage and seldom used in clinic practice.The aim of the study was to examine the effect of alveolar surgery on orthodontic tooth movement and to learn whether alveolar surgery can be a safe and effective way to facilitate the orthodontic tooth movement.This study set up the experimental animal models on alveolar surgery-aided tooth movement firstly. Beagle dogs were selected as subjects in...
