The Effect of Marginal Seal of Veneering DiCor (trade name) Substrates with DiCor Plus Porcelain
Abstract
A clinical crown preparation on a maxillary right central incisor dentoform tooth was made. Forty standardized wax patterns for a Dicor crown (control) and two different coping designs were cast, cerammed, and fit to their respective gypsum dies. Dicor Plus porcelain was applied to half of the specimens of two different substrate designs. All restorations were tacked to their respective dies to permit measurement of the marginal seal with a measuring microscope. The die casting assemblies were embedded in clear resin, sectioned faciolingually and mesiodistally, then measured in cross-section. Dicor restorations have acceptable physical properties, are locally and systemically biocompatible, have clinically acceptable fit, and, within the limitations of surface coloration, are esthetically pleasing. However, surface coloration does not take full advantage of laminated, multilayer porcelain build-up techniques. These techniques make possible the reproduction of more complex and intricate internal color characterizations seen in natural teeth. For this reason Dicor Plus porcelain was developed. The purpose of this study was to evaluate the effect on marginal seal of firing Dicor Plus porcelain to two different Dicor substrate designs.
