Evidence is limited on the efficacy of zirconia-based fixed dental prostheses.
The purpose of this systemic review was to assess zirconia-based FDPs in terms of survival and complications.
Searches performed in PubMed databases were enriched by hand searches to identify suitable publications. The keywords used were: "zirconia" and "fixed dental prosthesis," "zirconia" and "crown," "zirconia" and "fixed partial denture" and "humans," "zirconia" and "crown" and "humans," "crown" and "all-ceramics," and "fixed partial denture" and "all-ceramics". Titles and abstracts were read to identify literature that fulfilled the inclusion criteria. Only peer reviewed clinical studies published in the English language from January 1999 through June 2011 were included.
Twelve clinical studies based on zirconia, framework design, and porcelain veneering technique met the inclusion criteria. Of the studies identified, 1 was a randomized clinical study with 3-year follow-up results; the others were cohort prospective studies. Clinical complications included chipping of veneering porcelain, abutment failure, and framework fracture. One study investigated pressed ceramics as the veneering material and found no chipping of veneering porcelain after 3 years.
Short term clinical data suggest that zirconia-based fixed dental prostheses may serve as an alternative to metal ceramic fixed dental prostheses in the anterior and posterior dentition.
关于氧化锆基固定义齿修复体的疗效，证据有限。
本系统评价的目的是评估氧化锆基 FDP 在前牙和后牙修复中的存活率和并发症。
在 PubMed 数据库中进行了检索，并通过手工检索来补充相关文献，使用的关键词有：“氧化锆”和“固定义齿修复体”，“氧化锆”和“牙冠”，“氧化锆”和“固定局部义齿”和“人类”，“氧化锆”和“牙冠”和“人类”，“牙冠”和“全瓷”，以及“固定局部义齿”和“全瓷”。阅读标题和摘要以确定符合纳入标准的文献。仅纳入 1999 年 1 月至 2011 年 6 月期间发表的、以英语撰写的同行评议的临床研究。
有 12 项基于氧化锆、支架设计和瓷贴面技术的临床研究符合纳入标准。在确定的研究中，有 1 项为 3 年随访结果的随机临床研究，其余均为队列前瞻性研究。临床并发症包括瓷层崩裂、基牙失败和支架断裂。有 1 项研究调查了使用压制陶瓷作为饰面材料，发现经过 3 年随访后没有瓷层崩裂。
短期临床数据表明，氧化锆基固定义齿修复体在前牙和后牙修复中可能是金属陶瓷固定义齿修复体的替代选择。
