In the present invention, a ZrO2/porcelain composite material is used around the abutment, and, because of considerations related to aesthetics, this composite material is used as a core in the same manner as zirconia, and the surface of the core is covered with porcelain. The mechanical properties of the composite material are adjusted so as to minimize damage to the opposing teeth in the occlusion area. The porcelain ratio in the parts below the occlusion area may be given a sloped distribution to impart a sloped function to hardness and strength characteristics, such as increasing the strength, in order to prevent fracturing. |
