ABSTRACT:
The disclosure relates to an artificial tooth crown composed of glass ceramics comprising crystallized calcium phosphate forming essentially apatite which is a main inorganic component of natural bones or teeth. The disclosure also relates to a method of producing the artificial tooth crown. The artificial tooth crown has superior dimensional accuracy since it is made by precision casting. The tooth crown can be securely adhered by a dental cement such as glass ionomer. Furthermore, the physical properties of the tooth crown are very similar to those of the natural teeth, and the wear caused by the biting motion between the tooth crown and its mating tooth does not differ from that caused by the biting motion between the natural teeth. Furthermore, the method does not differ from the conventional precision casting method.
