Abstract

An artificial tooth for molars is of a double structure comprising an occlusal region replaceable by a material which is more durable than a synthetic resin and is selected from the group consisting of a metal, a ceramic, a composite resin and an amalgam, and a bottom region. The present artificial tooth may further include a junction region having a maximum thickness of 0.05 to 3.0 mm, which serves to make a bond between the occlusal and bottom regions of the artificial tooth.
