The present invention relates to a method of bonding a high strength zirconia post capable of acting as a core in a crystallized glass block in manufacturing an artificial tooth by a CAD / CAM processing method using a crystallized glass block as an artificial tooth material, A method of bonding a fixture and a metal link fastened to a zirconia column, and a crystallization glass capable of bonding to a zirconia column, and a method of manufacturing the same. To this end, the lithium disilicate crystallized glass containing the crystal crystal of the present invention comprises 10 to 15% by weight of Li 2 O, 68 to 76% by weight of SiO 2 , 2 to 5% by weight of P 2 O 5 serving as a nucleating agent, 0 to 5% by weight of Al 2 O 3 , 2 to 3% by weight of ZrO 2 , 0.5 to 3% by weight of CaO for increasing the thermal expansion coefficient of glass, Na 0 to 2.0% by weight of a mixture of MgO, ZnO, F and La 2 O 3 , containing 0.5 to 5% by weight of 2 O, 0.5 to 5% by weight of K 2 O and 1 to 2% by weight of a colorant, . |
