两种不同材质自攻型种植体支抗钉的临床稳定性研究

Research on the Clinical Stability of Two Kinds of Self Tapping Implant Anchorages

目的比较不锈钢和钛合金两种不同材质自攻型种植体支抗钉的临床稳定性。方法将使用微型种植体支抗钉的病例39例随机分为两组,分别用不锈钢和钛合金两种不同材质自攻型种植体支抗钉,共植入种植支抗钉106个,观察比较两种不同材质种植体支抗钉的临床稳定性。结果不锈钢自攻型种植体支抗钉的临床稳定成功率为90.74%,钛合金自攻型种植体支抗钉的临床稳定成功率为88.46%,两种不同材质自攻型种植体支抗钉的临床稳定性的差异无统计学意义。结论不锈钢自攻型种植体支抗钉的临床稳定性能达到传统钛合金种植体支抗钉的水平,因其具有操作简便,价格低廉的优势,可更多地应用于正畸临床。

Objective To compare the clinical stability between two kinds of self tapping implant anchorages：stainless steel and titanium alloy.Methods 39 cases of mini implant anchorages were randomly divided into two groups.Stainless steel and titanium alloy self tapping implant anchorages were used respectively.106 implant anchorages were planted totally.Clinical stability was observed and compared between two kinds of self tapping implant anchorages.Results The clinical success rate of stainless steel self tapping implant anchorage was 90.74%,while The clinical success rate of titanium alloy self tapping implant anchorage was 88.46%.There was no statistical significance between two kinds of implant anchorages.Conclusions The clinical stability of stainless steel self tapping implant anchorage is equal to the traditional titanium alloy self tapping implant anchorage.Due to the simpler operation and lower price,the stainless steel self tapping implant anchorage will be used more and more in orthodontic clinical practice.
