摘要

Veneers were fabricated by CEREC CAD-CAM and the platinum foil techniques for standardized preparations on 10 artificial teeth. Mesial preparation contacts were broken, but distal contacts remained intact. The veneers were cemented in a standardized manner to their teeth. The veneers and their attached cement were embedded in epoxy resin and sectioned twice gingivally-incisally and mesially-distally to produce eight sections. Three-way ANOVA disclosed that the main effects of fabrication method, section location, and measurement point location as well as all interaction terms significantly affected fit (P < 0.05). However, the difference in mean overall fit between the fabrication methods was too small to be of clinical importance. Restoration of the broken approximal contact did not compromise fit. Incisal margins had the greatest marginal openings. Surface measurement point locations were less well adapted than internal locations. Fit maps for CEREC and platinum foil veneers were strikingly similar.
