Embodiment 1

[0022] figure 1 It is the process flow chart of making zirconium dioxide of the present invention, as figure 1 As shown, the preparation process of the present invention is as follows: use a three-dimensional scanner to scan the dental model to form a virtual dental model image, then use a computer to design and restore the denture on the virtual image, and after the design is completed, transmit the data to a five-axis linkage CNC machine tool , after the zirconia block is processed by CNC machine tools, it is soaked and dyed, and then sintered to complete the production.

[0023] More detailed preparation process for making zirconia dentures:

[0024] 1. Preparation before scanning

[0025] Placing abutments on clay: Secure the abutments without shaking during scanning.

[0026] 2. Dental model scanning

[0027] Put the abutment to be scanned into the 3shape D700 scanner, open the 3shape dental manager client design software in the computer, and select the corresponding ...

Embodiment 2

[0047] 1. Preparation before scanning

[0048] Placing abutments on clay: Secure the abutments without shaking during scanning.

[0049] 2. Dental model scanning

[0050] Put the abutment to be scanned into the 3shape D700 scanner, open the 3shape dental manager client design software in the computer, and select the corresponding material according to the design sheet in the design software interface: zirconia, tooth position, type: inner crown / Full form, and then click the scan button to scan. The resulting image after scanning is in DCM format.

[0051] 3. Computer 3D graphics (design)

[0052] After scanning, open the design button in the design software to design. The main content of the design is to:

[0053] Inner crown: occlusal degree, adjacency is 1.5MM, thickness of crown is 0.55MM, space required for upper porcelain, strength is 1200MPA, beautiful.

[0054] Full-shaped crown: occlusal degree, adjacency, crown thickness 0.55MM, strength 1200MPA, beautiful.

Abstract

The invention relates to the field of false teeth and in particular relates to a preparation method of a zirconium dioxide false tooth. The preparation method comprises the following steps: scanning a tooth model via a three-dimensional scanner, transmitting data to a computer, designing through the computer, further transmitting the well designed data to a five-axis numerical control machine tool, completing tooth processing treatment through the five-axis numerical control machine tool, taking out a product, then performing dyeing, and further placing into a sintering furnace for sintering. Compared with the prior art, according to the preparation method disclosed by the invention, a manual false tooth manufacturing process is fundamentally changed, and traditional waxing, casting, porcelain coating and porcelain turning are replaced by computer design and digital processing; and the process steps are simplified, the digital processing precision is improved, a zirconium dioxide all porcelain crown which can not completed by the manual process can be realized, and the tooth esthetical restoration means of a clinician and the quality of the false tooth can be improved.

Description

technical field [0001] The invention relates to the field of dentures, in particular to a preparation method of zirconia dentures. Background technique [0002] Existing dentures are made by hand-made wax-type, casting, porcelain, and then car porcelain. Its procedure is complicated, and preparation is poor, and product intensity is not enough, and efficiency is low. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a preparation method of zirconia dentures. [0004] The scheme adopted by the preparation method of the present invention is that the three-dimensional scanner scans the dental mold and then transmits the data to the computer, and after computer design, the designed data is then transmitted to the five-axis CNC machine tool, and after the five-axis CNC machine tool processes the teeth The product is taken out for dyeing and then put into a sintering furnace for sintering. [0005] Preferably, th...
