Embodiment 1

[0025] a tooth such as figure 1 As shown, the inner crown 1 is included, and the inner crown 1 is used as a basic bracket to form the basic structure of the denture by 3D printing. The outermost side of the inner crown 1 is covered with a body porcelain layer, and the body porcelain layer 2 is made of porcelain powder. The outer surface of the crown 1 is made of zirconia material after cutting, grinding and sintering, and a paste 3 is provided between the body porcelain layer 2 and the inner crown 1, and the paste 3 is used to fill the body porcelain layer 2 and the inner crown 1 The gap between them, the paste 3 is a mixture of resin and ceramics. The function of the paste is: it is used to fix the body porcelain layer and the inner crown, more precisely, it is to make the body porcelain layer 2 and the inner crown 1 more stable, so that the two are not easy to be deformed or shifted. If the patient is using When dentures are used, excessive occlusal force of the teeth may e...

Embodiment 2

[0028] A method of making the tooth of claim 1, comprising the steps of:

[0029] Step 1, collect and correct the data of three-dimensional parameters of the teeth that need to be made into dentures, and restore the simulated tooth model;

[0030]Step 2, production of the inner crown 1: According to the simulated tooth model obtained in the above step 1, a basic bracket of the tooth is produced by using 3D printing technology;

[0031] Step 3, production of body porcelain layer 2: according to the structure of inner crown 1 obtained in step 2, make body porcelain layer 2 on its outer layer, the volume of body porcelain layer 2 is larger than that of inner crown 1, body porcelain layer 2 is The zirconia material is CNC-cut by a cutting and grinding device to form a zirconia ceramic layer structure;

[0032] Step 4, filling of the paste body 3: filling the mixture of resin and ceramic between the body porcelain layer 2 and the inner crown 1, and then sintering the whole to form...

Abstract

The invention relates to artificial teeth, and in particular discloses a tooth and a making method of the tooth. The tooth comprises an inner crown, wherein the inner crown is used as a basic support; a basic structure of the artificial teeth is formed by adopting three-dimensional printing; the outmost side of the inner crown is coated with a body porcelain layer; the body porcelain layer is formed by adopting porcelain powder and adopting a zirconia material on the outer surface of the inner crown through cutting, grinding and sintering; a paste body is arranged between the body porcelain layer and the inner crown, is used for filling a gap between the body porcelain layer and the inner crown and is a mixture of resin and porcelain. The making method of zirconia complete-porcelain tooth comprises the processes of data collecting, data processing and the like and the means of an all-around three-dimensional scanning mode, data transmission and the like, so that an HD (High Definition) tooth simulating and restoring image can be generated, parameters of the obtained artificial teeth can be more accurate, and the artificial teeth are more fit with the oral cavity of a human body.

Description

technical field [0001] The invention relates to a tooth, in particular to a zirconia all-ceramic tooth and a preparation method thereof. Background technique [0002] Dentures currently used clinically, the inner crown is usually made of nickel-chromium alloy material, the denture manufacturing process often needs to add beryllium, because the denture needs to be bonded in the oral cavity for a long time, but long-term contact with beryllium in the denture will cause Harmful to the human body, and some people, especially women, will have an allergic reaction to nickel, which will darken the gums and harm health and beauty. Moreover, if the denture inlaid in the oral cavity is a metal-containing porcelain crown, it will be affected or even removed when head X-ray, CT, and MRI examinations are required. Now there are more and more materials for making dentures, but if the sintering is not good or accidents occur during the sintering process, the dentures will not be strong en...
