【摘要】 目的分析比较Nobel非平台转移和Dentium平台转移种植系统修复5 a后的临床效果。方法选择2013年1—12月在郑州市口腔医院接受义齿种植的160例患者,分为A组(Nobel Replace种植系统)与B组(Dentium superline种植系统),每组80人。对两组患者修复5 a后进行X线检查,计算牙槽骨吸收量,测试种植体基台扭矩,记录基台松动例数,用SPSS 19.0软件进行统计分析,对两种系统的种植效果进行评价。结果 A组对种植体周围骨吸收值大于B组,差异有统计学意义(t=21.327,P<0.001)。A组扭矩大于B组,差异有统计学意义(t=7.554,P<0.001)。两组松动率比较,差异无统计学意义(χ~2=0.480,P=0.488)。结论具有平台转移的种植系统可减少种植体边缘的骨吸收,但需要注意其可能引起的机械并发症。更多还原

【Abstract】 Objective To analyze and compare the clinical effects of Nobel’s non-platform switching and Dentium’s platform switching which were restoration by 5 years.Methods The 160 patients who received denture implant in Zhengzhou Stomatology Hospital from January to December 2013 were divided into group A(Nobel Replace implant system) and group B(Dentium superline implant system), 80 in each group. After 5 years of restoration, X-ray examination was performed to calculate the alveolar bone absorption, the torsion value of implant abutment were tested and the cases of abutment loosening were recorded. Statistical analysis was carried out with SPSS 19.0 software to evaluate the implant effect of the two systems.Results Group A had a statistical difference for peri-implant bone resorption values greater than group B(t=21.327,P<0.001). Group A had more torque than group B(t=7.554,P<0.001). There was no statistical difference in loosening rate between the two groups(χ~2=0.480,P=0.488).Conclusion Platform switching can reduce bone resorption, but attention should be paid to the possible mechanical complications.更多还原
