Abstract

The purpose of this review article was to summarize the scientific literature investigating all invitro methods that can evaluate both marginal and internal adaptation of direct and indirect restorations. An electronic search of publications from 2000 to March 2022 was made using ScienceDirect, PubMed, and Google Scholar databases. The search included only English-language articles. Therefore, only studies that addressed techniques to measure marginal and internal adaptation in different restorations were selected. Five laboratory methods with different capabilities have been introduced to check the adaptation of dental restorations, including sectioning, Silicon Replica Technique (SRT), Micro-CT, OCT, and triple scan method. In addition, there are factors that may contribute to differences between different methods in measuring adaptation, including 2D, 3D, and absolute adaptation, cost, and feasibility of performing in the oral cavity. SRT and traditional sectioning have the advantage of being simple and inexpensive procedures. Micro-CT, OCT, and triple scan method are costly procedures that necessitate specialized equipment and analysis software which enable both 2D and 3D analysis. Another crucial aspect of the assessment techniques to be applied in clinical trials is the capability to conduct an examination in the oral cavity. Sectioning, OCT, and Micro-CT cannot be used to make assessments in the oral cavity, however SRT and triple scan method can. The search for an ideal and standardized device to measure the adaptation of direct and indirect restorations in dentistry is still needed.
