Comparison of T-loop vs Opus Loop in Canine Retraction Efficacy and Anchorage Loss Control

Comparison of T-loop vs Opus Loop in Canine Retraction Efficacy and Anchorage Loss Control - a Split- Mouth, Randomized Clinical Trial

The primary aim of this split-mouth randomized control trial is to compare the rate of canine retraction between the T loop and the Opus loop. The secondary objectives are to compare the angulation of the canine, changes in the first molar position in terms of anchorage loss, and molar rotation for the two loops used T-loop and Opus loop will be placed randomly on the right and left quadrants of patients for canine retraction and outcomes will be measured before and after completion of canine retraction

T-loop and Opus loop will be placed in the right and left quadrants of the patient for canine retraction after initial leveling and alignment. canine retraction rate will be measured by using a calibrated caliper every month. canine angulation will be evaluated by periapical x-ray which will be taken before and after completion of canine retraction and anchorage loss and molar rotation will be assessed by model analysis
