Abstract:
The study compared the thickness of conventional (Tru-Fit and Belle de St. Claire) and all-ceramic (Dicor and Cerestore) die spacers. Three coats of Tru-Fit, two coats of Belle de St. Claire, and two coats of Cerestore die spacers provided a 25 microns thickness. A single coat of the Dicor spacer resulted in a 37 microns layer. A significantly thinner layer occurred at the convex occlusal line angles for all of the materials tested. This could impede the flow of the luting agent at the time of cementation.
