Marginal fit of direct temporary crowns.

This study compared the effect that shrinkage of four brands of temporary crown and fixed partial denture resins has on the marginal fit of crowns made from them. Under the conditions of this study, crowns made from Coldpac had marginal discrepancies approximately four times larger than those made from Scutan. Crowns made from Snap and Trim had marginal discrepancies approximately two times larger than those made from Scutan.
