ABSTRACT

This investigation examined the influence of the fabrication technique on the marginal fit of porcelain veneers. Ceramic veneer restorations were made with both feldspathic porcelain and cast glass ceramic materials for the labial surface of a maxillary central incisor. The feldspathic porcelain veneers were made by using both the platinum foil and refractory die techniques, and the cast ceramic veneers were fabricated in thicknesses of 0.5 mm and 1.0 mm. The fit of each veneer was measured before and after sectioning. The marginal openings for the intact veneers increased in the following order: platinum foil, refractory die, cast ceramic (0.5 mm), and cast ceramic (1.0 mm). A similar trend was observed for the sectioned specimens where the technique of fabrication (P < .001) and the site of measurement (P < .05) were found to have a significant effect on the fit of the veneers.
