Background: To evaluate and compare the relationship between the amount of root resorption after the intrusion of maxillary anterior teeth using two different intrusion mechanics i.e. Intrusion arch (Utility arch) and Miniimplants through CBCT scans. 20 patients randomly selected were divided into 2 groups: Group A: 10 patients with intrusion arch mechanics and Group B: 10 patients with mini-implant mechanics. Pre- and post-intrusion sectional CBCT scans of maxillary anterior teeth were taken. Changes in volumetric measurements (in mm3 ), linear measurements (in mm), and angular measurements (in degree) between pre and post-intrusion scans were measured for each incisor in both groups using paired t-tests. An independent t-test was used for comparing the change in all three parameters between both groups. Pearson’s correlation test was done for correlating the amount of root resorption with the amount of intrusion for each incisor in both groups. Results: Changes in all three parameters between pre-and post-treatment CBCT scans for all incisors for each group and between both groups were statistically significant. Pearson’s correlation shows a statistically nonsignificant correlation for all incisors in both groups except lateral incisors in group B. Conclusion: Clinically significant root resorption is observed with the intrusion of maxillary anterior teeth either with utility arch or mini-implants. The amount of root resorption and range of intrusion is more with miniimplants, while the amount of proclination is more with the use of utility arch. More amount of root resorption is seen in lateral incisors than in central incisors in both groups.
