Abstract

The purpose of thislaboratory study was to examine the compressive strength of ceramic veneers of different thicknesses bonded with two different resin cements.A total of 40 ceramic specimens (5x10mm) in dimensions were fabricated according to manufacturer’s instructions. Specimens were randomly divided according to their thicknesses (1 & 2 mm) into two groups (G1, G2), with 20 samples each. Each group was further subdivided two subgroups(RelyX, G-CemLinkAce) according to luting agent applied. All specimens went through thermocycling (1500 cycles between 5-55°C) and compressive test. According to the Kruskal-Wallis test (P<0.05), the highest mean compressive strength value was observed in the GC 2mm group (30.670 ± 2.992 MPa), whereas the lowest mean compressive strength value was observed in RelyX 1mm group 10.380 ± 3.278 MPa). The visual analysis data suggest that GC 2mm group was the only group that showed 100% failures as mixed.The ideal thickness of the veneer should be up to 1.0 mm for high translucency of the veneer andproper polymerization of the luting cement.
