摘　　要：目的:采用meta分析的方法评价瓷基台和钛基台修复后的临床效果。方法:计算机检索Pub Med、Cochrane Library、EMbase、Ovid、万方数字化期刊全文数据库、中国期刊全文数据库、中文科技期刊全文数据库、中国生物医学文献数据库自建库至2014年6月间公开发表的比较瓷基台和钛基台修复临床效果的随机对照实验文献,对纳入研究文献进行严格的质量评价及数据提取,采用Rev Man 5.2进行Meta分析。结果:最终纳入12篇符合纳入排除标准的文献,共709名患者,实验组(瓷基台)434个,对照组(钛基台)399个。Meta分析显示:与钛基台相比,瓷基台可以减少骨吸收量[MD=-0.08,95%CI(-0.11,-0.05),P<0.00001]及探诊深度[MD=-0.14,95%CI(-0.25,-0.04),P=0.005],但其改良出血指数高于钛基台[MD=0.14,95%CI(0.05,0.23),P=0.001],差异有统计学意义。在牙龈退缩[MD=0.12,95%CI(-0.31,0.55),P=0.59]及植体周围牙龈黏膜色泽[MD=-0.14,95%CI(-5.03,4.75),P=0.95]方面两者差异无明显统计学意义。结论:瓷基台在临床应用中有一定优势,但受纳入研究的数量、质量及测量指标不全面等的限制,本次Meta分析结果尚有待于高质量的大样本随机对照实验予以证实。Objecive：To use a meta-analysis technique to estimate the clinical effect of ceramic and titanium abut-ment,in oder to providing guidance for clinical application. Method：The relevant randomized controlled trials were searched from PubMed,the Cochrane Library,EMbase,Ovid,WangFang Data,CNKI,VIP and CBM databases up to June, 2014. After data extraction and quality evaluation of included trials,then meta-analysis was conducted using RevMan 5.2 software. Result：A total of twelve articles were found to meet the eligibility criteria,involving 719 patients were included, test group （n=422,ceramic abutment）,control group （n=397,titanium abutment）.The results of meta-anaylsis showed that compare to titanium abutment,ceramic abutment can reduce the bone loss[MD=-0.08,95%CI（-0.11,-0.05）,P＆lt;0.00001] and Probing pocket depth[MD=-0.14,95 %CI（-0.25,-0.04）,P =0.005],but titanium abutment was better at mean bleed-ing index（mBI）[MD=0.14,95%CI（0.05,0.23）,P=0.001],with siginificantdifferences.No significant difference were found in the gingival recession[MD=0.12,95%CI（-0.31,0.55）,P=0.59],the color of peri-implant mucosa.[MD=-0.14,95%CI （-5.03,4.75）,P=0.95]. Conclusion：Due to the quantity and quality limitation of included studies,more large sample and, high quality RCTs are required to verify this meta-analysis conclusion.
