title: Marginal adaption of two esthetic complete crowns.
abstract: In an in-vitro study twenty artificial crowns were fabricated. A hardened stainless steel five piece die assembly was used to construct uniformed wax patterns and to record all measurements. The fit of ten PFM crowns before and after the application of porcelain using the porcelain but margin technique was compared to that of ten Dicor crowns. The results of this study indicated best fit with the metal crowns before the application of porcelain, while the PFM crowns were oversized and the Dicor crowns were undersized.
