Abstract
(EN)
The present invention relates to a method for preparing a zirconia multi-layered block for artificial teeth and, more specifically, comprises: a first material mixing step of mixing 3 mol% yttrium oxide-tetragonal zirconia polycrystal and an organic binder; a second material mixing step of mixing 3 mol% yttrium oxide-tetragonal zirconia polycrystal, 5 mol% yttrium oxide-tetragonal zirconia polycrystal and an organic binder; a third material mixing step of mixing 5 mol% yttrium oxide-tetragonal zirconia polycrystal and an organic binder; a compression molding step of sequentially injecting the mixtures, which are prepared through the first material mixing step, the second material mixing step and the third material mixing step, into a mold for compression molding and compression molding the same; and a calcination step of calcining the molded product compression molded through the compression molding step. The method, which comprises the steps, for preparing a zirconia multi-layered block for artificial teeth controls the content of yttrium oxide during the preparation process, thereby providing a zirconia multi-layered block for artificial teeth which exhibit a color similar to that of natural teeth after being immersed in a staining solution.

La présente invention concerne un procédé de préparation d'un bloc multicouche de zircone pour dents artificielles et, plus spécifiquement, comprend : une première étape de mélange de matériau consistant à mélanger 3 % en mol d'oxyde d'yttrium-polycristal de zircone tétragonal et un liant organique; une deuxième étape de mélange de matériau consistant à mélanger 3 % en mol d'oxyde d'yttrium-polycristal de zircone tétragonal, 5 % en mol d'oxyde d'yttrium-polycristal de zircone tétragonal et un liant organique; une troisième étape de mélange de matériau consistant à mélanger 5 % en mol d'oxyde d'yttrium-polycristal de zircone tétragonal et un liant organique; une étape de moulage par compression consistant à injecter séquentiellement les mélanges, qui sont préparés dans la première étape de mélange de matériau, la deuxième étape de mélange de matériau et la troisième étape de mélange de matériau, dans un moule pour moulage par compression et à mouler par compression ceux-ci; et une étape de calcination consistant à calciner le produit moulé par compression dans l'étape de moulage par compression. Le procédé, qui comprend les étapes, pour la préparation d'un bloc multicouche de zircone pour dents artificielles régule la teneur en oxyde d'yttrium au cours du processus de préparation, ce qui permet d'obtenir un bloc multicouche de zircone pour dents artificielles qui présente une couleur semblable à celle d'une dent naturelle après avoir été immergée dans une solution de coloration.
