Abstract:
(EN) The purpose of the present invention is to provide: a surface etchant composition for a dental zirconia ceramic, capable of etching the surface of a zirconia material within a short time while maintaining a constant etching rate and capable of ensuring safety while hardly causing smoke and odor during etching; a method for preparing a dental restorative by using the same. The etchant composition comprises hydrofluoric acid, sulfuric acid, a catalyst and isopropyl alcohol, wherein the catalyst comprises hydrogen peroxide and a surfactant.
(FR) L'objet de la présente invention est de pourvoir à : une composition d'agent de gravure de surface pour une céramique de zircone dentaire, capable de graver la surface d'un matériau de zircone en un court laps de temps tout en maintenant un taux de gravure constant et capable de garantir la sécurité tout en générant peu de fumée et d'odeur lors de la gravure ; et un procédé de préparation d'une restauration dentaire l'utilisant. La composition d'agent de gravure selon l'invention comprend de l'acide fluorhydrique, de l'acide sulfurique, un catalyseur et de l'alcool isopropylique, où le catalyseur comprend du peroxyde d'hydrogène et un tensioactif.
(KO) 본 발명은, 에칭속도를 일정하게 유지하면서 짧은 시간에 지르코니아 소재의 표면에 에칭이 가능하고, 에칭시 연기 및 냄새를 거의 유발하지 않으면서 안전성을 확보할 수 있는 치과용 지르코니아 세라믹의 표면 에칭제 조성물 및 이를 이용한 치아수복물의 제조방법을 제공하기 위한 것으로, 상기 에칭제 조성물은 불산, 황산, 촉매제 및 이소프로필알콜을 포함하되, 상기 촉매제는 과산화수소와 계면활성제를 포함하는 것을 특징으로 한다.
