초록
The purpose of this study was to evaluate the marginal fitness of collarless metal-ceramic crown formed with direct lift technique using wax compared with metal-ceramic crown with metal butt margin. Twenty crowns, ten were collarless metal-ceramic crowns and ten were metal-ceramic crowns with metal butt margins, were made and cemented on epoxy resin dies, and their marginal openings were measured on scanning electron microphotographic prints at x200 magnification. The results were as follows; 1. In the case of collarless metal-ceramic crowns, the mean marginal opeining was
