False tooth and manufacturing method thereof

Abstract

The invention relates to a false tooth, and particularly discloses a false tooth and a manufacturing method thereof. The false tooth comprises an inner crown. The inner crown serves as a basic support. A basic structure of the false tooth is formed in a three-dimensional printing mode. The outermost side of the inner crown is wrapped by a dentin porcelain layer. The dentin porcelain layer is formed in the mode that porcelain powder is cut, ground and sintered on the outer surface of the inner crown through a zirconium oxide material. A paste body is arranged between the dentin porcelain layer and the inner crown, and a gap between the dentin porcelain layer and the inner crown is filled with the paste body. According to the zirconium-oxide all-porcelain tooth manufacturing method, the data collecting process, the data processing process and the like are carried out, an omni-directional three-dimensional scanning mode, a data transmission means and the like are adopted, a high definition tooth simulation and restoration image can be generated accordingly, the parameters of the manufactured false tooth are more accurate accordingly, and the false tooth is better attached to the oral cavity of the human body.

Description

technical field

[0001] The invention relates to a denture, 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 ...

Embodiment 1

[0028] a denture such as figure 1 As shown, the inner crown 1 is included. The inner crown 1 is used as a basic bracket, and the basic structure of the denture is formed by 3D printing. The outermost side of the inner crown 1 is covered with a body porcelain layer 2. The body porcelain layer 2 is made of porcelain powder The outer surface of the inner 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, and the paste 3 is used to fill the body porcelain layer 2 and the inner crown 1 the gap between. The function of paste 3 is to fix the body porcelain layer and the inner crown, more precisely, to make the body porcelain layer and the inner crown more stable, so that the two are not easy to deform or deviate. Sometimes, due to the excessive occlusal force of the teeth, it is easy to cause the denture to be out of alignment, and the function of the paste is to make the posit...

Embodiment 2

[0033] A method for making teeth, comprising the steps of:

[0034] 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;

[0035] 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;

[0036] Step 3, production of body porcelain layer 2: according to the structure of the inner crown 1 obtained in step 2, a body porcelain layer is made on its outer layer. The volume of the body porcelain layer 2 is larger than that of the inner crown 1. The body porcelain layer is cut and ground The device performs numerical control cutting on the zirconia material to form the zirconia ceramic layer 2 structure;

[0037] Step 4, filling of paste body 3: filling the mixture of resin and ceramic between the body porcelain layer and the inner crown, and then sinteri...
