Summary

1. To compare maxillary canine retraction rate among conventional (labial) vs dual (simultaneous labial and palatal) force mechanics using labial fixed orthodontic appliances. 2. To assess the biomechanical effects of dual force vs single force In this study we will be using the most common method i.e. labial fixed appliances with different techniques to find a more faster and controlled method of canine retraction with least undesirable movements. Lingual appliances are difficult to apply in normal practice but it has many advantages like faster movement of teeth, less anchorage loss so by using dual force we will have advantages of lingual appliance in combination with the conventional labial technique.

Detailed description

This split mouth study was conducted on 45 patients in which extraction of maxillary first premolars is their orthodontic treatment plan. Patient's maxillary arch was randomly subdivided (through chit method) into control and experimental groups. Labial fixed orthodontic appliances were used in all patients included. GROUP 1 includes canine retraction through conventional (labial) force. GROUP 2 includes canine retraction through dual (labial as well as palatal) force. Critical anchorage was used. Rate of canine retraction was measured through Vernier calipers intraorally as well as on study casts at following time points. T0: just before canine retraction. T1-T6: 1-6 months of canine retraction.
