Abstract

The purpose of this study was to compare the adaptation of laminate veneers milled using the dental CAD/CAM CEREC2and CEREC3systems. An artificial resin tooth of the upper-left incisor was prepared for laminate veneer restoration. The prepared tooth was subjected to optical impression procedures using either CEREC2or CEREC 3. The adaptation of the laminate veneer restoration was evaluated by a cement-replica method using an injection type of silicon impression material. Each silicon replica specimen was sectioned in the buccolingual direction through the center of the labial surface with a surgical knife. Film thicknesses were measured at three points (incisal, center and gingival) on the cut surface using a stereomicroscope. The mean film thicknesses of the respective CEREC2and CEREC3groups were 185±49μm and26±16μm for the incisal, 245±37±μm and95±35 μm for the center and212±87μm and30±20μm for the gingival. Significant differences between the two groups were recognized by one way ANOVA and Bonferroni correction of multiple comparison. It was concluded that the CEREC3system showed a better fit of laminate veneer restorations than the CEREC2system.
