Clinical effect and quantity analysis of micro-implant anchorage in molar distalization of orthodontics
Objective:To evaluate the clinical effect and quantity of the molar distalization combined with micro-im-plant anchorage technology in different classification of orthodontics.Methods:Sixty patients were choosen who accept Mclaughlin Bennett Trevisi(MBT)treatment and molar distalization with micro-implant anchorage.Analyzing quantity of mo-lar distalization by measuring preoperative and postoperative digital cast and CBCT.Results:There was no statistical differ-ence in the success rate of micro-implant anchorage between different types of Angle malocclusions(P＞0.05),but there was a statistical difference in the distal distance of the maxillary second molar between Angle Ⅰ and Angle Ⅱ(P＜0.05),and there was a statistical difference in the distal distance of the mandibular second molar between Angle Ⅰ and Angle Ⅲ(P＜0.05).Conclusion:Micro-implant anchorage can provide stable anchorage and the demandable space of distalization in light and moderate crowding case.This research providing implant method,implant position and the data as clinical reference in the case of molar distalization.
