Embodiment Construction

[0032] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0033] First of all, in the field of modern dentistry, all-ceramic crowns are high-strength non-metallic crowns instead of metals, decorated with dentin porcelain and incisal porcelain, and the current excellent ceramic materials include alumina and zirconia.

[0034] Furthermore, as shown in the table below, the process parameters of dry pressing and cold isostatic pressing are adopted for the undyed ceramic block of the present invention, that is to say, the ceramic powder must first be subjected to a forming process to form a ceramic block 1. In the embodiment of the present invention, the ceramic powder is colored or colorless, and the ceramic block 1 further includes zirconia powder, wherein zirconia has excellent properties of high toughness, chemical corrosion resistance and good biocompatibility, And it...

Abstract

The present invention discloses a dental mold gradational-layer ceramic block and a manufacture method thereof. The dental mold gradational-layer ceramic block comprises a ceramic block, wherein one end of the ceramic block contains a first color zone, the other end of the ceramic block contains a second color zone, and the gradational colors exist between the first color zone and the second color zone. The manufacture method comprises: A. providing at least two dyeing liquids with different colors and a ceramic block, B. concurrently soaking the opposite both sides of the ceramic block respectively with the two dyeing liquids so as to make the opposite both sides of the ceramic block respectively absorb the dyeing liquids, C. taking the soaked ceramic block, and standing, D. carrying out heat drying on the standing ceramic block, and E. sintering the dried ceramic block so as to obtain the ceramic block containing at least the two color zones and having the gradational colors. With the structure and the steps, the dental mold gradational-layer ceramic block has the gradational colors, and meets the aesthetic requirement of the people on the teeth.

Description

technical field [0001] The invention relates to a dental mold gradient porcelain block and its manufacturing method, in particular to a kind of gradient color that is soaked in two different colors of dyeing liquids in different directions at the same time, and then left to stand, dried and sintered to form a gradient color. dental mold blocks. Background technique [0002] First of all, in order to realize that the ceramic body is homogeneous or close to homogeneous in the powder forming process, dry powder pressing and isostatic pressing are mainly used as new powder forming processes developed in the last century. Homogenization of green bodies not only requires advanced powder molding equipment, but also the quality of ceramic powder preparation, that is, each single powder particle is homogeneous and controllable, so the cost is relatively high. [0003] Also, as shown in the table below, the process parameters of ceramic blocks are formed by dry pressing and cold isos...
