Xive和Ankylos 2种种植系统单牙修复的临床疗效评价

目的评价Xive和Ankylos 2种种植系统在临床应用中的优缺点。方法选择527例采用Xive种植系统和82例采用Ankylos种植系统的单冠种植体患者,进行潜入式种植手术,Ⅰ期术后4~6个月,Ⅱ期术后2周,全部采用金钯合金烤瓷冠修复。结果取印模修复时,Xive、Ankylos种植体成功率分别为98.5%、97.6%。修复后1年Xive、Ankylos的修复成功率分别为98.8%、100.0%。Xive种植体牙槽骨边缘骨吸收在修复即刻和修复后1年时分别为-0.32（-0.40~0.00）mm和-0.12（-0.18~0.00）mm,Ankylos分别为0.08（-0.15~0.12）mm和0.40（0.10~0.62）mm。结论 2种种植系统各有优缺点,根据患者的临床特点选择合适的系统可取得满意的疗效。

Comparison of Clinical Effects of Xive and Ankylos Implant Systems

Objective To evaluate the advantages and disadvantages of Xive and Ankylos implant systems in clinical application.Methods Five hundred and twenty-seven patients were treated with Xive implants and 82 patients with Ankylos implants for single crown restorations.Au-Pd alloys were used for metal-ceramic restorations 4 to 6 months after Ⅰ-stage operation and 2 weeks afterⅡ-stage operation.Results At the second stage of operation,the implant survival rate was 98.5% for Xive and 97.6% for Ankylos.After 12 months,the restorative success rate was 98.8% for Xive and 100.0% for Ankylos.At the second stage of operation and 12 months after restorations,the marginal bone loss for Xive was-0.32（-0.40-0.00）mm and-0.12（-0.18-0.00）mm,respectively,and the marginal bone loss for Ankylos was 0.08（-0.15-0.12）mm and 0.40（0.10-0.62）mm,respectively.Conclusion Each of the two implant systems has its advantages and disadvantages.In order to get satisfactory clinical results,appropriate implant systems should be selected according to the clinical characteristics of patients.
