探讨不同植入术式对老年微创种植牙初期稳定性的影响

To Investigate the Effect of Different Implantation Methods on the Initial Stability of Minimally Invasive Dental Implants in Elderly Patients

目的探讨不同植入术式对老年微创种植牙初期稳定性的影响。方法选取2015年9月-2016年8月在我院接受治疗的老年上颌前磨牙区后天性牙缺失患者70例进行研究,分为常规备洞组、级差备洞组、骨挤压组三组,记录并对比各组的扭矩值以及术后各时间段的ISQ值。结果相比于常规备洞组,级差备洞组和骨挤压组在扭矩和ISQ值方面均与之存在明显差异(P<0.05),有统计学意义;术后12 W测量ISQ值,三组的ISQ值差异不显著(P>0.05),无统计学意义。结论级差备洞和骨挤压技术应用于老年微创种植牙初期稳定性的维护中,效果显著,值得推广。

Objective To investigate the effect of different implantation methods on the initial stability of minimally invasive dental implants in elderly patients.Methods The study was performed from September 2015 to August 2016 in our hospital for treatment of elderly patients with maxillary premolar area after tooth loss in 70 cases,divided into normal group,differential cavity preparation cavity preparation group,bone extrusion group three groups,record and groups were compared to the torque value and every time after ISQ.Results Compared with the conventional cavity group differential cavity preparation group and bone extrusion group in torque and ISQ values were different(P<0.05),there was statistical significance;12 W measurement of ISQ value after operation,three groups of ISQ values had no significant difference(P>0.05),no statistical significance.Conclusion The application of graded preparation and bone extrusion technique in the maintenance of the initial stability of minimally invasive dental implants in elderly patients has obvious effect and is worthy of promotion.
