A ZrO2- porcelain composite material is used around the abutment, and from the viewpoint of aesthetics, the composite material is used as a core in the same manner as zirconia, and the surface is covered with porcelain. In addition, the porcelain ratio is slanted, such as adjusting the mechanical properties of the composite material so that the biting part can minimize damage to the opposing teeth, and making the lower part more difficult to break It may be distributed to give a gradient function to the hardness and strength characteristics.支台の周りにＺｒＯ２－陶材複合材料が用いられ、審美性の観点から、ジルコニアと同じようにこの複合材料をコアとして用い、その表面に陶材を被覆する。また、咬合する部分を対合歯へのダメージを最小に抑えられるように複合材料の機械的性質を調整し、それより下部は破折しにくくするため高強度にするなど、陶材比率を傾斜配分させて、硬さ、強度特性に傾斜機能を持たせてもよい。
