摘要： 目的:观察氧化锆全瓷修复种植体边缘骨吸收变化,评估氧化锆全瓷修复体长期临床效果。方法:将首都医科大学电力教学医院2014年1月—2016年1月间78例采用氧化锆全瓷修复系统进行固定义齿修复的病例纳为研究对象,随访5年,检测修复体完整性、密合性、种植体存留情况,并检测改良龈沟出血指数（mSBI）、改良菌斑指数（mPLI）及牙周探诊深度（PD）,应用X线片评估种植体边缘骨吸收,使用多元线性回归分析影响骨吸收的相关因素。采用SPSS 19.0软件包对数据进行统计学分析。结果:随访期间,6例患者未按规定复诊,随访脱落,脱落率为7.69%（6/78）,剩余72例患者（共80颗种植体,63个修复体）完成随访,种植体均未出现松动、折断、脱落,种植体存留率为100.00%。6个修复体出现崩瓷,2个修复体冠边缘与基台间不密合,无修复体脱落。全口曲面体层片与根尖片提示,边缘骨吸收0~2.03 mm,平均（0.23±0.04）mm。统计分析显示,糖尿病史、修复体种植方式、崩瓷及对颌牙类型影响种植体边缘骨吸收量（P<0.05）。结论:长期随访结果显示,氧化锆种植体存留率高,软组织美学效果好,边缘骨稳定,是一种可靠的植入系统。

Abstract: PURPOSE: To analyze peri-implant bone resorption of zirconia implants, so as to evaluate the value of zirconia all-ceramic restorations for clinical use. METHODS: Seventy-eight patients receiving all-ceramic fixed partial denture with zirconia framework from January 2014 to January 2016 were prospectively enrolled, and a five-year follow-up was carried out. The restoration integrity, margin sealing, implant retention rate, modified sulcus bleeding index (mSBI), modified plaque index (mPLI) and probing depth (PD) were evaluated. Radiographs were used to evaluate implant marginal bone resorption, and the related factors affecting bone resorption were determined using multiple linear regression analysis. SPSS19.0 software package was used for data analysis. RESULTS: The follow-up period was 5 years. During the follow-up period, a total of 6 patients were lost to follow-up. The remaining 72 patients (a total of 80 implants and 63 prostheses) completed the follow-up. None of the implants showed loosening, fracture or displacement. Porcelain fragmentation occurred in 6 restorations, poor fit between the crown edge and the abutment occurred in 2 restorations, and no restorations fell off. The mean value of marginal bone resorption was (0.23±0.04) mm(0-2.03 mm). Statistical analysis displayed that history of diabetes, porcelain fragmentation and type of dental implant affected peri-implant bone resorption of zirconia implants(P<0.05). CONCLUSIONS: Long-term follow-up results show that zirconia implant is a reliable implant system with high survival rate, good soft tissue aesthetic effect, and marginal bone stability.
