摘要：
The present invention relates to a method for treating the bonding surfaces of dental restoration and to dental restoration. According to one aspect of the present invention, disclosed is a method for treating the bonding surfaces of dental restoration in which the bonding surface of a zirconia core whereon a ceramic layer is to be placed is etched by a solution comprising a mixture of nitric acid (HNO3) and hydrofluoric acid (HF) to improve bonding strength when manufacturing the dental restoration consisting of the zirconia core in the lower portion and the ceramic layer in the upper portion. [Reference numerals] (S100) Determine a tooth shape through 3D modeling (using a 3D optical camera and obtaining a 3D optical image；(S200) Form a zirconia core by mechanically processing a zirconia block in a CAD/CAM method for the tooth shape；(S300) Sinter the zirconia core；(S400) Etch the bonding surface of the zirconia core；(S500) Form dental restoration by placing a ceramic layer on the zirconia core；(S600) Calcine the dental restoration본 발명은 치아수복물의 접착면 처리방법 및 치아수복물에 관한 것이다. 본 발명의 일 측면에 따르면, 하부의 지르코니아 코어와 상부의 도재 층으로 이뤄진 치아수복물의 제조에 있어서, 도재 층이 축성될 지르코니아 코어의 접착면을 질산(HNO3)과 불산(HF)의 혼합 용액으로 에칭하여 접착 강도를 향상시키는 것을 특징으로 하는 치아수복물의 접착면 처리방법이 개시된다.
