The invention relates to a dental crown, including a metal inner crown for covering the upper outer edge of the patient's primary tooth / implant abutment tooth； and a ceramic layer, the average thickness of which is less than the average thickness of the metal inner crown, and the inner edge and outer edge of the ceramic layer are the same as the outer edge of the metal inner crown； and a bright glaze layer: laid along the outer edge of the ceramic layer.The average thickness of the ceramic layer created in the new model is less than the average thickness of the metal inner crown, and the inner edge and outer edge of the ceramic layer are the same as the outer edge of the metal inner crown； for bite and food hardness resistance, in addition to the better elasticity and toughness of the metal, the protection of the patient's primary teeth / implant abutment teeth is more thorough and durable.本新型創作關於一種牙冠，包括ㄧ金屬內冠供覆設於患者原生牙/植牙治台齒(Abutment)上部外緣；以及ㄧ陶瓷層，該陶瓷層之平均厚度小於該金屬內冠之平均厚度，且該陶瓷層之內緣與外緣均相同於該金屬內冠外緣；以及一亮釉層：係沿該陶瓷層之外緣所鋪設。本新型創作該陶瓷層之平均厚度小於該金屬內冠之平均厚度，且該陶瓷層之內緣與外緣均相同於該金屬內冠外緣；對於咬合與抵抗食物硬度，除金屬具有較佳之彈韌性之外，對於患者原生牙/植牙治台齒(Abutment)之保護更為周密，且經久耐用。
