To determine the survival rates of implant-supported monolithic zirconia crowns and fixed partial dentures (FPD).
An electronic search for articles in the English language literature published from January 1, 2001 to September 17, 2021 was performed using PubMed, Scopus, and CENTRAL search engines. After applying predetermined inclusion and exclusion criteria, the definitive list of selected articles was used for calculating the interval survival rate (ISR) and cumulative survival rate (CSR). Restoration failure in this study was defined as the fracture or compromise of any part of the ceramic restoration that required the removal or remake of the implant-supported restoration.
The electronic search resulted in 457 titles. The systematic application of inclusion and exclusion criteria resulted in 14 clinical studies that addressed the clinical outcomes of implant-supported monolithic zirconia crowns and fixed partial dentures. Of these, 3 were randomized controlled trials, 5 were prospective studies, and 6 were retrospective studies. Follow-up periods ranged from 1 to 5 years. Of the 644 implant-supported monolithic zirconia restorations computed in this systematic review, there was only 1 reported failure of the monolithic zirconia restorative material over a follow-up period of up to 5 years, for a cumulative survival rate of 99.84%. At the maximum follow-up interval of 5 years, the cumulative survival rate for monolithic zirconia single crowns was 100% and the cumulative survival rate for monolithic zirconia fixed partial dentures was 99.60%.
Implant-supported monolithic zirconia single crowns and fixed partial dentures have excellent short-term (<5 years) survival rates but the evidence for medium-term survival (>5 years) and beyond is lacking.
确定种植体支持的整体式氧化锆全冠和固定局部义齿（FPD）的生存率。
使用PubMed、Scopus和CENTRAL搜索引擎对2001年1月1日至2021年9月17日发表的英文文献进行电子检索。在应用预定的纳入和排除标准后，将选定文章的最终列表用于计算区间生存率（ISR）和累积生存率（CSR）。本研究中修复失败定义为陶瓷修复体任何部分的断裂或损坏，需要拆除或重新制作种植体支持的修复体。
电子检索得到457个标题。纳入和排除标准的系统应用产生了14项临床研究，这些研究涉及种植体支持的整体式氧化锆全冠和固定局部义齿的临床结果。其中，3项为随机对照试验，5项为前瞻性研究，6项为回顾性研究。随访期为1至5年。在本系统评价中计算的644个种植体支持的整体式氧化锆修复体中，在长达5年的随访期内，仅报告了1例整体式氧化锆修复材料失败，累积生存率为99.84%。在5年的最大随访间隔时，整体式氧化锆单冠的累积生存率为100%，整体式氧化锆固定局部义齿的累积生存率为99.60%。
种植体支持的整体式氧化锆单冠和固定局部义齿具有出色的短期（<5年）生存率，但缺乏中期（>5年）及更长时间的生存证据。
