两种种植体支抗钉在正畸治疗中的临床应用分析

【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。更多还原

【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.更多还原
