摘 要

目的:探讨我院常用的国产及进口两种种植体支抗钉临床应用效果。方法:收集60例强支抗成人正畸患者,随机分两组,分别植入国产及进口支抗钉,植入部位均在上颌双侧第二前磨牙和第一磨牙根间,共120颗,分析两种支抗钉折断率、脱落率、植入手术操作难易、患者术中反应及术后支抗钉周围菌斑指数。结果:两组支抗钉折断率、脱落率、患者术中反应及术后支抗钉周围菌斑指数相比较,均无显著差异(P>0.05)。国产支抗钉植入手术操作较进口支抗钉困难,差异有统计学意义(P<0.05)。结论:国产和进口支抗钉在临床应用中均能达到理想效果。

Abstract

Objective To investigate clinical application effects of domestic and imported implant anchorages which are commonly used in our hospital.Methods 60 adult patients with strong anchorage were randomly divided into two groups, domestic and imported anchorages were implanted, respectively. A total of 120 anchorages were implanted between the maxillary bilateral second premolar and the first molar, and to analyze the fracture rate ,shedding rate, thedifficulty of implant operation, intraoperative reaction and the plaque index of the two implant anchorages. Results Compared with implanting imported anchorages, it is more difficult to implant domestic anchorages and the difference is significant(P<0.05) . While, the other indicators of the two groups were not statistically significant(P>0.05). Conclusion Both domestic and imported implant anchorages can achieve ideal results in clinical application, and each has advantages and disadvantages, which is worthy of clinical promotion.

隨着经济生活水平的日益提高,对美的追求让越来越多的人选择正畸治疗,通过矫正牙齿来达到排齐牙齿、改善面部美观,提高颜值的目的,而正畸治疗成功的关键就是支抗控制。传统的支抗控制措施主要是采取口外装置,如口外弓、J钩等,而这些辅助装置依赖于患者的配合,需要长时间佩戴,既不舒适也不美观甚至影响日常生活。由于种植体支抗钉的出现、材质的不断更新及植入方法的成熟,传统支抗控制装置已基本被淘汰,而种植体支抗钉在正畸舞台上大放光彩,因其体积小,舒适度高,易操作,效果稳定等优点成为正畸医生的宠儿。此外,种植体支抗钉在正畸治疗中还有诸多其他作用,如压低前牙,改善露龈笑;压低磨牙,解决开合;牵引埋伏牙等等[1]。现在市面上种植体支抗钉种类繁多,本研究就我院常用的国产及进口两种种植体支抗钉的临床应用进行分析,比较两者之间的临床应用效果,为临床使用提供理论依据。
