Comparative evaluation of effects of space closure with and without canine retraction
AUTHOR(S): Kulsum Guroo and Mohammad Mushtaq
To evaluate the efficacy of closing loop during retraction by comparing the effect on incisors and anchorage unit with and without canine retraction.
Materials and Methods: 30 patients treated with first bicuspid extraction were randomly divided into two groups. In Group I canine retraction was carried out before space closure after which tear drop shaped closing loop was given. In Group II no canine retraction was carried out and tear drop loop was given for space closure. The duration of the study was four months. Lateral Cephalograms were taken at the start (T0) and end of study period (T4).
Results: Group II shows statistically significant reduction in incisor inclination in relation to the NA and SN line. A statistically significant change was seen on the anchorage unit on comparing the two groups. The horizontal distance from molar to ptv was increased in Group II. Group I showed lesser mesial movement of the molar in relation to ptv.
Conclusion: The effects found during retraction were different in both the groups. The incisor inclination and mesial movement of molars was significantly greater in group II as compared to the group I.
