后牙区植入钛锆小直径种植体的临床观察

The clinical observation of implant small-diameter titanium-zirconium implant in posterior tooth area

目的:探讨钛锆小直径种植体在后牙区的稳定性。方法:选择2015年5月到2016年11月来就诊的30名患者,共36枚种植体,其中后牙区应用钛锆小直径种植体16枚,常规种植体20枚,应用钛锆小直径的设为实验组,常规种植体设为对照组,比较两组负重1年的存留率;负重时间;种植体周菌斑指数(PLI)、种植体周改良出血指数(mBI)、探诊深度(PD)。数据用PASW statistic 18.0软件进行统计学分析。结果:两组负重1年存留率为100%;实验组平均负重时间明显短于对照组;两组骨吸收量、牙龈稳定性没有显著性差异。结论:钛锆小直径种植体在后牙区可以取得满意的临床效果。

Objective： To evaluate stability of the titanium-zirconium small diameter implant in the posterior tooth area. Method： 36 implants of 30 patients from May 2015 to November 2016, were randomly divided into two groups,16 titanium-zirconium small diameter implants were applicated in the experimental group, 20 conventional implants were applicated as the control group. The plaque index（PLI）,the modification sulcus bleeding index（mBI）, the probing depth I（PD）, the load time, the success rate of dental implants were compared. Data using PASW 18.0 statistic software for statistical analysis. Results： Two groups of success rate are 100%, The experimental group the average load time is shorter than the control group obviously, there is no significant difference about the bone absorption, gum stability between the two groups. Conclusion： Satisfactory clinical effects can be obtain by titanium-zirconium small diameter implant in the posterior tooth area.
