目的：对氧化锆全瓷固定桥在后牙种植区的临床应用效果进行初步评估。方法：随访2011-07～2012-06采用种植体支持的全瓷固定桥修复后牙缺失的47位患者（53个修复体，共120枚种植体）的临床资料。记录种植体的失败数量、修复体失败数量、机械及生物并发症情况。结果：37例43个修复体、100个种植体随访12～24个月。随访病例中共有9个修复体（20．9％）出现崩瓷，9颗种植体（9．0％）存在种植体周围黏膜炎。修复体存留率100％，种植体存留率100％。所有种植体和修复体均未出现松动、脱落、折断等现象。结论：种植体支持的氧化锆全瓷固定桥用于后牙种植修复是可行的。

Objective:To evaluate the outcome of implant-supported all-ceramic fixed partial prostheses (FPPs)in posterior area. Methods:The clinical data of 1 20 implants-supported 53 fixed dentures in 47 patients were collected from July 201 1 to June 201 2 and prospectively studied.Complication and failure of implants and /or prosthesis,biological and technical complications were evaluated. Results:43 restorations with 1 00 implants in 37 cases were followed up for 1 2 -24 months.Veneering ceramic chipping was observed in 9(20.9%)prostheses.Inflamed marginal gingivitis was found around 3(7.0%)prostheses.No implant was involved in technical complication.Cumulative survival rate was 1 00% for implant-based analysis and 1 00% for prostheses-based analysis.Conclusion:Implant-supported all-ceramic fixed partial dentures may be a feasible treatment modality for posterior dental restoration.
