摘要： 目的:对比两种材质(钛钉和不锈钢钉)微螺钉种植体支抗植入上颌后牙根间区的脱落率,并对各类影响因素进行分析,为医生选择设计提供参考。方法:102例正畸患者平均年龄21岁(13~46岁)。正畸设计强支抗,在上颌后牙根间区共植入172枚微螺钉种植体支抗。研究按照种植体类型(钛钉1.6 mm×8 mm,不锈钢钉1.5 mm×8 mm)、骨面型(高角和非高角)和年龄(成人和青少年)进行分组。统计分析使用SPSS 13.0软件包。采用卡方检验比较种植体类型、骨面型、年龄对脱落的影响。结果:种植体类型和骨面型对脱落率的影响具有统计学意义(P<0.05);成年和青少年脱落率的差别无统计学意义。结论:钛钉植入上颌后牙根间区稳定性优于不锈钢钉。高角患者种植体脱落率较高。

Abstract: Objective: To compare the stability of two kinds of micro-screw system placed in maxillary posterior area. Methods: 102 patients were selected with 176 micro-screws placed. Possible influencing factors including the kinds of micro-screws, age and skeletal patterns were analyzed by Chi-square tests through SPSS Statistical Package. Results: Different kinds of micro-screws and different skeletal patterns exhibited significantly different failure rates (P<0.05). No significant difference was found between age groups. Conclusion: Higher failure rates were conformed in group of stainless steel micro-screws compared with Ti-alloy micro-screws. The failure rates in high angle cases were higher than those of lower and average angle cases.
