The purpose of this study was to examine the marginal and internal fit of all ceramic crowns fabricated by dental CAD/CAM “Cerec 2” system. This system was also compared with the laboratory heat-press technique “IPS Empress 2” system.“Cerec 2” crowns were made under two test conditions of spacer values; 1) 0μm group (n=10) and 2) 30μm group (n=10). On the other hand, “IPS Empress 2”crowns were made according to the manufac-uturers'instructions (n=10). All of test crowns were seated on the preparations with ad-hesive cement. The specimens were cut mesiodistally at the central portion. The thickness of resin cement layer at seven measuring points on cut surfaces was measured using a measuring microscope. In addition, when applying “Cerec 2” system, chair time from tooth preparation to cementation was measured.<BR>The findings are as follows;<BR>1. The overall mean thickness of cement layer of “Cerec 2” crowns was 222±57μm forthe Qum group and 193±32μm for the 30μm group. These values were significantly thickerthan that of “IPS Empress 2” crowns (125±37μm)(p<0.01). However, there was no significantdifference (p>0.01) in marginal fit between the 30μm group of “Cerec 2” crowns (100±58μm and 105±65μm) and “IPS Empress 2” crowns (90.5±63μm and 123±73μm).<BR>2. Average chair time for “Cerec 2” chair-side restoration was about 90 minutes fromtooth preparation to cementation.
