Abstract: Abstract: Objective to evaluate the treatment effects of improved segmental arch wire combined with mini-implant anchorage on patients with moderate and severe dentition crowding and anterior labial inclination. Methods: 12 patients with moderate and severe dentition crowding and anterior labial inclination were selected. The fixed orthodontic appliance combined with improved segmental arch wire and mini-implant anchorage technology were used to align the dentition, close the space and reduce anterior proclination. The changes of before and after treatment were analyzed through the cephalometric and model measurement, and the therapeutic effect was evaluated. Results: After correction, the crowding of dentition and labial inclination of anterior teeth were reduced significantly, the overjet and overbite of anterior teeth was normal, and the occlusion of posterior teeth was stable. Conclusion: the improved segmental arch wire combined with mini-implant anchorage technology can avoid the alternate motion of anterior teeth in the process of correction, shorten the treatment time and obtain ideal correction effect.
