The porcelain laminate veneer and inlay are fabricated by the indirect methods in which the porcelain powder is molded on the refractory investment cast and fired in the furnace. The purpose of this study is to evaluate the ability of the investment material to reproduce the impression surface by examining the surface roughness of the investment cast as well as the contact angle of the investment slurry with various impression materials. It was found that the surface roughness became smaller when the investment was cast into the rubber base impressions than into the hydrocolloid impressions. It is recommended from the results to use rubber base impression materials for these techniques. However, great care must be taken in casting the investment since they showed poorer wettability with the investment slurry.
