摘要
目的探讨微型自攻钛钉种植体支抗的临床应用效果。方法选取2014年2月~2016年1月我院正畸科收治的60例成人双颌前突患者作为研究对象,根据随机数字表法将其分为观察组与对照组,每组各30例。对照组患者给予口外弓支抗矫正,观察组患者给予微型自攻钛钉种植体支抗矫正。比较两组患者的矫治效果、治疗依从性及矫治前后SNA、SNB指标水平变化。结果所有患者都顺利完成矫治,磨牙关系均达到Ⅰ类关系。观察组患者的种植成功率为96.7%。观察组患者治疗期间的依从性为96.7%,对照组为76.7%,观察组患者治疗期间的依从性高于对照组,差异有统计学意义(P<0.05)。观察组患者矫治前后的SNA角减少幅度[(0.42±0.33)°]大于对照组[(0.24±0.14)°],差异有统计学意义(P<0.05)。结论微型自攻钛钉种植体支抗的临床应用具有较佳的支抗作用,正畸治疗成功率比较高,能提高治疗依从性,值得临床推广。
Objective To investigate the clinical application effect of mini self tapping titanium implant anchorage. Methods From February 2014 to January 2016,60 cases of adult biomaxillary protrusion who treated in orthodontics department of our hospital were selected as subjects and divided into the observation group and the control group according to the random number table method,30 cases in each group.The control group was treated with extraoral arch anchorage,and the observation group was treated with mini self tapping titanium implant anchorage.The correction ef- fect,the treatment adherence and the change of SNA,SNB index before and after dental treatment were compared be- tween the two groups.Results All patients were successfully completed dental treatment and were reached the class I relationship of molar.The successful rate of planting in the observation group was 96.7% .The compliance of the observation group during dental treatment was 96.7%,while the compliance was 76.7% in the control group,the index in the observation group was higher than that of the control group,and the difference was statistically significant （P〈0.05）.The decrease of the SNA angle in the observation group was [（0.42±0.33）°],while the decrease of the SNA angle in the control group was [（0.24±0.14）°],and the difference was statistically significant （P〈0.05）.Conclusion The clinical application of mini self tapping titanium implant anchorage has better anchorage effect,and the orthodontic treatment has higher success rate and increase the compliance,so it deserves clinical promotion. ]
