The aim of this study was to compare the treatment efficiencies and root resorption amounts of two different incisor intrusion mechanics. Material and Methods: Thirty-two patients with deep bite and elongated maxillary incisors were randomly allocated two treatment groups: Connecticut intrusion arch group (CG) or Mini-implant group (MG). In both groups approximately 60 g of force applied between central and lateral incisors. Dentoalveolar effects were studied via cephalograms taken before and after 5 months of intrusion while root resorption was assessed using periapical roentgens. Paired t-test was used to evaluate differences within groups. The changes observed in both groups were compared by using independent t-test. Results: While the overbite reduced significantly in both groups (p<0.001), this amount was greater in MG (p<0.01). The center of resistance (CR) of incisors showed significant apical movement (p<0.001) in both groups with greater values observed in MG (P<0.05). The labial tipping and sagittal advancement of the incisor edge was significant in the treatment groups (p<0.001); these changes were greater in MG. Apex of the central incisor displayed significant backwards movement (p<0.05) with no intergroup difference (p>0.05). Incisors in both groups showed significant root resorption (P<0.000) which was significantly greater in MG compared to CG (P<0.05). Conclusion: Mini-implants were more efficient in bite-opening. However they also led to more root resorption and labial tipping compared with the Connecticut intrusion arch.
