Abstract
The objective of this study is to compare the rate of canine retraction between conventional labial retraction force versus palatal retraction force with labial appliance.
Subjects and methods
This prospective randomized clinical study was conducted on a sample of 26 patients recommended for upper first premolar extraction as part of their orthodontic treatment plan. The patient ages ranged from (16-26) years. Patients were randomly divided into two groups; Group I: Thirteen patients, treated with Roth brackets 0.022-inch slot for labial orthodontic appliance with palatal retraction force. Group II: Thirteen patients, treated with Roth brackets 0.022-inch slot for labial orthodontic appliance with labial retraction force.
Results
The canine retraction rate was measured clinically using dental vernier at monthly intervals. The distance measured was between maxillary canine cusp tip and maxillary first molar mesiobuccal cusp tip. Measurement was done till closure of the extraction space (when both canines touch the mesial surface of the upper second premolars)
Conclusion
1. Both methods of retraction with labial or palatal force could be effective in canine retraction.
2. There is no significant difference between both ways on the rate of canine retraction.
