Background: Dental implants are widely used and in order to answer to esthetic demands, zirconia has been introduced as an abutment material as an alternative to titanium. Several studies have been published on this topic, but the results have been often inconsistent. The objective of the present study is to systematically analyze the existing literature comparing clinical outcomes of titanium and zirconia implant abutments. The study was designed as a systematic review of systematic reviews. Methods: This systematic review is in accordance with the Transparent Reporting of Systematic Reviews and Meta-analyses. A MEDLINE/PubMed, Cochrane Database of Systematic Reviews and SCOPUS literature search was performed up to and including June 2021. Data were extracted independently by two reviewers and tAMSTAR2 was used to assess the quality of the systematic reviews. Results: The electronic search identified 1146 papers, and 175 duplicates were removed. After manual screening, 954 studies were excluded and the final analysis was conducted on 11 papers. Both mechanical and esthetic outcomes and biological complications were analyzed. Conclusions: It can be concluded that titanium abutments have a better mechanical resistance than zirconia ones. Plaque accumulation is reported to be slightly higher on titanium but without any significant inflammatory process. The esthetic outcomes seem to be more related to the thickness (>3 mm) of the soft tissues than to the abutment material.
牙种植体应用广泛，为满足美学需求，氧化锆已作为基台材料被引入，以替代钛。关于这一主题已发表了多项研究，但结果往往不一致。本研究的目的是系统分析现有文献，比较钛和氧化锆种植体基台的临床结果。该研究设计为对系统评价的系统评价。方法：本系统评价遵循系统评价与Meta分析的透明报告原则。截至2021年6月，进行了MEDLINE/PubMed、Cochrane系统评价数据库和SCOPUS文献检索。由两名审阅者独立提取数据，并使用tAMSTAR2评估系统评价的质量。结果：电子检索识别出1146篇论文，去除175篇重复文献。经过人工筛选，排除954项研究，最终对11篇论文进行分析。对机械和美学结果以及生物学并发症进行了分析。结论：可以得出结论，钛基台比氧化锆基台具有更好的机械抗力。据报道，钛表面的菌斑堆积略高，但无任何明显的炎症过程。美学结果似乎与软组织厚度（>3mm）的关系比与基台材料的关系更大。
