钛锆小直径种植体在双尖牙区即刻种植中的应用

The application of small-diameter titanium-zirconium implant in immediate implantation in bicuspid area

目的:探讨钛锆小直径种植体在双尖牙区即刻种植的应用。方法:选择2015年6月到2017年3月来就诊的40名患者,采用即拔即种方法共46枚种植体,其中应用钛锆小直径种植体22枚,常规种植体24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;种植体近远中及颊舌向骨量变化。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;两组骨吸收量比较有显著性差异。结论:钛锆小直径种植体在双尖牙区即刻种植的效果优于常规直径植体。

Objective： To investigate the application of titanium-zirconium small diameter implant in immediate implantation in the bicuspid area. Method： 46 implants of 40 patients from June 2015 to March2017, were randomly divided into two groups, 22 titanium-zirconium small diameter implants were applicated as the experimental group, 24 conventional implants were applicated as the control group. The changes of bones mass were observed, the load time, the success rate of dental implants were compared.Data using PASW 18.0 statistic software for statistical analysis. Results： The retention rate of the two groups was 100% in 1 years. The average loading time in the experimental group was significantly shorter than that in the control group, and there was significant difference in bone resorption between the two groups. Conclusion： The effect of immediate implantation of titanium-zirconium small diameter implant in bicuspid area is better than that of conventional diameter implant.
