Root Resorption Concomitant with Two Different Canine Retraction Mechanics (A Prospective Clinical Study)

Aim: Acceleration of orthodontic treatment and achieving the desired results is essential for the patients and orthodontist, which increases the importance of finding the best method to accelerate tooth movement. it seems important to compare the rate of root resorption when canine retraction is performed by two different mechanics assuming that there will be less root resorption with lingual retraction mechanics.. Subjects and Methods: This is a prospective randomized clinical study that was conducted on a total sample of 26 orthodontic patients recommended for upper first premolar extraction as part of their orthodontic treatment plan. The patient ages were ranged from (16-26) years. Group I: Thirteen orthodontic patients were treated with Roth brackets 0.022-inch slot for a labial orthodontic appliance with palatal retraction force. Group II: Thirteen orthodontic patients were treated with Roth brackets 0.022-inch slot for a labial orthodontic appliance with labial retraction force.. Results: There is statistically non-significant difference in canine length and canine root resorption between the two studied groups.. Conclusion: Both methods of retraction with labial or palatal force could be effective in canine retraction.
