【摘要】：背景:微种植体在正畸治疗中作为"绝对支抗"而被广泛应用于临床,然而脱落率较高一直是其主要缺点。影响微种植体的稳定性主要包括微种植体的自身因素、微种植体周围炎、微种植体的植入方式、角度、位置和加载时机等。目的:就近年来国内外学者对影响微种植体支抗稳定性的因素做一综述。方法:第一作者应用计算机以"微种植体、稳定性、正畸支抗"为中文检索词,以"miniscrews、stability、orthodontic anchorage"为英文检索词,分别在CNKI和PubMed数据库检索近四年发表的有关文章。结果与结论:共纳入52篇文章。综合国内外学者有关微种植体稳定性的相关研究结果表明,微种植体表面的改性能有效增强骨结合能力,促进骨再生,提高微种植体的稳定性。在正畸临床治疗中,应该结合患者的骨质情况,选择合适的微种植体和植入方式,适宜的植入角度以提高微种植体的稳定性,同时避免损伤牙根、神经、血管和上颌窦,并注重术后愈合期的维护,适时加载。
[Abstract]:Background: microimplants are widely used as "absolute Anchorage" in orthodontic treatment. The stability of microimplants mainly includes the factors of microimplant itself, peri-implant inflammation, the way, angle, location and loading time of micro-implant. Objective: to review the factors affecting the stability of microimplant Anchorage in recent years. Methods: the first author used the computer to search the related articles published in CNKI and PubMed database in the last four years with "microimplant, stability, orthodontic Anchorage" as the Chinese key word and "miniscrews,stability,orthodontic anchorage" as the English key word. Results & conclusion: 52 articles were included. The results show that the surface modification of microimplants can effectively enhance the ability of bone bonding, promote bone regeneration and improve the stability of microimplants. In orthodontic clinical treatment, we should choose appropriate microimplants and implants, appropriate implantation angles to improve the stability of microimplants, and avoid damage to root, nerve, blood vessels and maxillary sinuses in orthodontic clinical treatment. And pay attention to the maintenance of postoperative healing period, timely loading.
