Problems solved by technology

[0004] The structure of different material layers of the above-mentioned denture is complicated. After the patient is inlaid, in the process of daily chewing food, due to the low adhesion between different materials, the different materials of the denture will gradually peel off, resulting in frequent The denture needs to be repaired, but the repaired denture cannot guarantee long-term durability, which increases the cost and workload of the patient's dental care, and seriously affects the overall aesthetics of the patient's teeth

Embodiment 1

[0045] A zirconia all-ceramic crown, such as figure 1 and figure 2 As shown, including zirconia layer 1, the outer surface of zirconia layer 1 is coated with bonding layer 2, dentin porcelain layer 3, enamel porcelain layer 4, transparent porcelain layer 5 and glaze layer 6, and bonding layer 2 is far away from zirconia The surface of the layer 1 is provided with microgrooves 7, and a plurality of grooves 8 form criss-cross mesh grooves to improve the adhesion between the zirconia layer 1 and the dentin porcelain layer 3, and the outer surface of the zirconia layer 1 is provided with grooves 8, thereby increasing the adhesion between the bonding layer 2 and the zirconia layer 1, and between the dentin porcelain layer 3, the enamel porcelain layer 4, the transparent porcelain layer 5 and the glaze layer 6, due to the similar molecular structure of the materials, the The connection strength between them is sufficient, so that the coated layers are not easy to peel off from the...

Embodiment 2

[0047] A zirconia all-ceramic crown, the difference from Embodiment 1 is that the grooves 8 are formed by the impact of the bonding layer 2 by the particles, the grooves 8 are point-shaped grooves, and a plurality of grooves 8 are scattered outside the bonding layer 2 The surface is used to increase the adhesion between the bonding layer 2 and the zirconia layer 1, so that the bonding layer 2 is not easy to peel off from the zirconia layer 1.

[0048] A method for manufacturing a zirconia all-ceramic crown, comprising the steps of:

[0049] S1. Scan the patient's dental data and enter it into the computer;

[0050] S2. Draw the denture design drawing through CAD technology;

[0051] S3. According to the design drawing, use CAM technology to process the zirconia inner crown and sinter it;

[0052] After the zirconia inner crown is sintered, the outer surface of the zirconia inner crown is sandblasted with a sandblasting machine; The sand particles on the outer surface of the...

Abstract

The invention discloses a zirconia all-ceramic crown, and relates to the field of denture manufacturing. The zirconia all-ceramic crown includes a zirconia layer,the outer surface of the zirconia layer is sequentially coated with a bonding layer, a dentine porcelain layer, a dental enamel porcelain layer, a transparent porcelain layer, and a glaze layer,and micro grooves are formed in the surface,away from the zirconia layer, of the bonding layer. Aiming at the problem that the glazed surface is prone to peeling off from a zirconia material in the prior art,the micro grooves are formed in thesurface,away from the zirconia layer, of the bonding layer, the bonding strength between the bonding layer and the dentine porcelain layer is improved, and the surface of a denture is prevented from peeling off.

Description

technical field [0001] The invention relates to the field of denture manufacture, in particular to a zirconia all-ceramic crown and a manufacturing method thereof. Background technique [0002] In today's society, people pay more and more attention to oral health, but in modern society, due to eating habits or bacterial infection, etc., modern people often have dental problems such as rotten teeth and tooth decay. In order to solve the above problems, patients generally choose inlaid dentures . [0003] The current full zirconia high-simulation denture structure, such as the Chinese patent with the patent publication number of CN106073920A, includes a zirconia layer and a glaze. Zirconium layer surface, glazed with imitation natural tooth pigments. [0004] The structure of different material layers of the above-mentioned denture is complicated. After the patient is inlaid, in the process of daily chewing food, due to the low adhesion between different materials, the diffe...
