Abstract：
BACKGROUND: Different methods are used for the analysis of marginal and internal fit of partial crowns, but not all of them are applicable for in vivo studies. The aim of this review is to search the available methods, described in the current literature, to assess marginal and internal fit in partial crowns.
METHODS: an electronic search was performed on Pubmed and Web of Science databases to find studies published from 1 January 2017 up to 2 March 2023, following PRISMA guidelines and Cochrane handbook for systematic reviews. The search strategy applied was: \"(marginal) AND (fit OR gap OR adaptation OR discrepancy) AND (inlay OR onlay OR partial crown)\". In vitro studies which evaluated marginal and internal fit on CAD CAM or 3D printed partial crowns were included in this review. Quality of the studies was assessed by using Quality Assessment Tool For In Vitro Studies (QUIN tool).
RESULTS: 22 studies were included. Among conventional methods, direct view with microscope, indirect view on resin replicas, and silicone replica technique (SRT) were used. Considering new digital methods, micro-CT, SRT 3D and triple scan technique (TST) were applied.
CONCLUSIONS: Among 2D methods, direct view technique is the most used marginal fit analysis. For a more comprehensive evaluation, a 3D digital analysis is suggested. SRT and indirect view are the only 2D methods available for in vivo analysis. A protocol for the application of TST for assessment in vivo is now available, but no studies are reported in literature yet.

摘要：
背景：不同的方法用于分析部分冠的边缘和内部拟合，但并非所有这些都适用于体内研究。这篇综述的目的是搜索可用的方法，在目前的文献中描述，评估部分冠的边缘和内部拟合。
方法：在Pubmed和WebofScience数据库上进行了电子搜索，以查找从2017年1月1日至2023年3月2日发表的研究，遵循PRISMA指南和Cochrane手册进行系统评价。应用的搜索策略是：“（边缘）和（适合或差距或适应或差异）和（嵌体或高嵌体或部分冠）”。本综述包括评估CADCAM或3D打印部分冠的边缘和内部配合的体外研究。通过使用体外研究质量评估工具(QUIN工具)评估研究质量。
结果：纳入22项研究。在常规方法中,用显微镜直接观察，对树脂复制品的间接看法，使用硅胶复制技术（SRT）。考虑到新的数字方法，Micro-CT,应用SRT3D和三重扫描技术（TST）。
结论：在2D方法中，直视技术是最常用的边际拟合分析。为了更全面的评估，建议进行3D数字分析。SRT和间接视图是可用于体内分析的唯一2D方法。现在可以使用TST进行体内评估的方案，但文献中还没有研究报道。
