Summary Accurate marginal fit and proper contour and surface finish of a temporary crown are needed to maintain healthy contiguous gingiva before the placing of the final restorations. In this study, the effect of two finish line types and the period of their remaining in the mouth on the marginal adaptation of temporary crowns was examined. According to our research findings, although no statistically significant difference was found between the marginal adaptation of the crowns of the chamfer and shoulder types, after 7 days a discrepancy of an important degree was observed in the shoulder type crown ( t = 2.379, P < 0.05).
