Comparison of the marginal fit of various ceramic crown systems

M F Abbate et al. J Prosthet Dent. 1989 May.

Abstract

This study evaluated the marginal fit of four ceramic crown systems, (1) metal ceramic crowns with a metal margin, (2) metal ceramic crowns with a porcelain facial margin, (3) Cerestore crowns, and (4) Dicor crowns. Measurements of the marginal adaptation were recorded from the facial and lingual margins by using a video-enhanced microscope with digital micrometer and image intensification in a high resolution television screen. Results indicate that all four crown systems yielded comparable and acceptable marginal fit.
