The aim of this systematic review was to analyze and compare the most up-to-date information available on long-term, medium-term, and short-term survival rates of porcelain laminate veneers (PLVs) and investigate the homogeneity in current studies or lack of it. An electronic search was performed using PubMed, Ovid MEDLINE, Cochrane Library, Web of Science, EBSCO, Science Direct, Wiley, and Scopus databases. Based on the PRISMA guidelines, the main inclusion criteria consisted of research articles published after the year 2000, studies with a follow-up period of at least 1 year and reporting of the Kaplan-Meier estimated cumulative survival rates. Quality assessment of the included studies was performed using the modified systematic assessment list consisting of 24 items. Thirty full-text articles were reviewed in detail. A total of 30 articles met the inclusion criteria and were selected for qualitative synthesis. The remaining 27 publications were retained to discuss the heterogeneity in the current literature and reported longevity of veneer restorations. A conclusive estimation of the longevity of PLVS beyond 20 years is lacking. The availability of evidence in the current literature is limited in terms of sample size and duration of follow-up. However, the majority of studies have concluded that PLVs have high-success rates and predictable patient outcomes. The present literature indicates an increased heterogeneity among research study designs. Researchers should aim for homogeneous study designs that can be included in systematic reviews and meta-analyses.
本系统评价的目的是分析和比较瓷贴面（PLV）长期、中期和短期生存率的最新信息，并调查当前研究中的同质性或缺乏同质性的情况。使用PubMed、Ovid MEDLINE、Cochrane图书馆、科学网、EBSCO、Science Direct、Wiley和Scopus数据库进行电子检索。根据PRISMA指南，主要纳入标准包括2000年后发表的研究文章、随访期至少为1年且报告Kaplan-Meier估计累积生存率的研究。使用由24项组成的改良系统评估清单对纳入研究进行质量评估。详细审查了30篇全文文章。共有30篇文章符合纳入标准并被选入定性综合分析。保留其余27篇出版物以讨论当前文献中的异质性以及报告的贴面修复体的使用寿命。目前缺乏对PLV超过20年使用寿命的确切估计。就样本量和随访时间而言，当前文献中的证据有限。然而，大多数研究得出结论，PLV成功率高且患者预后可预测。目前的文献表明研究设计之间的异质性增加。研究人员应致力于采用可纳入系统评价和荟萃分析的同质研究设计。
