Aim: To compare rate of canine retraction by using periodontally accelerated osteogenic orthodontics and conventional mechanotherapy using CBCT.
Material & Methods : The present study was conducted on patients who reported for routine orthodontic treatment. A sample of 10 patients who required bilateral maxillary 1st premolar extraction and canine retraction as a part of their orthodontic treatment were included for this study. A split mouth randomised technique was used to assess the retraction of upper canines. In this split-mouth design technique, upper canine of one side (right) was retracted with Periodontally Accelerated Osteogenic Orthodontics (PAOO) and on contralateral side it was done with conventional mechanotherapy.
Results: The rate of canine retraction on right side was 1.94 mm/month whereas on left side it was 1.15 mm/ month. Canines were retracted faster with the PAOO procedure and the difference was of 0.78 mm/month which was highly statistically significant with the p-value <0>
Conclusions: The rate of canine retraction was more on right side (PAOO) than on left (Conventional) side. Periodontally Accelerated Osteogenic Orthodontics (PAOO) helped canine move faster into the extraction space than the conventional mechanothery.Periodontally Accelerated Osteogenic Orthodontics (PAOO) helped to maintain the bone density level during the orthodontic tooth movement which decreased in the conventional
orthodontic tooth movement.
