Abstract
This study was performed to investigate the availability of adhesive resin cement for luting agent of cast crown. The resin cements used in this study were Panavia-Ex(Kuraray Co., Japan) and C & B-Metabond (Parkell Bio-Materials U. S. A.). Zinc phosphate cement was Flecks zinc cement(Mizzy Inc., U. S. A.) The film thickness of cast crown at gingival margin, lateral wall and occlusal surface was observed with measuring microscope(Modek MXT 70 Matsuzawa Seiki Co., Japan) and the retention of cast crown was measure with Instron Universal Test Machine(Instron Engineering Co., U. S. A.) @ES The results were as follows: @EN 1. Th value of retention o cast crown was the highest in the use of Panavia-EX, followed by C & B-Metabond and zinc phosphate cement, respectively. 2. There was no difference in film thickness among the three cements, but the film thickness in all cements was highest at occlusal surface.
