Abstract:
PROBLEM TO BE SOLVED: To provide a dental artificial tooth in which a bonding strength between a frame base and a resin is increased, for example, concerning the dental artificial tooth made of ceramics.SOLUTION: A dental artificial tooth includes a frame base 4 formed of ceramic materials, and a plurality of spherical beads 5 bonded on the surface of the frame base 4. In the present invention, the spherical beads are fixed on the surface of the frame base to form irregularities on the surface of the frame, and thereby the bonding strength is increased by that the resin fits in the irregularities. Furthermore, a portion where the resin strongly fits, so-called, an undercut is made between the frame base and the spherical beads, so that the resin strongly fits to the undercut part, resulting in further increasing the bonding strength between the frame and the resin being a facing part.
