Method for producing tooth crown through zirconia

[0024] Example 1: A method for producing a single crown using zirconia, including: scanning a tooth model with a three-dimensional scanner to obtain a virtual three-dimensional image, and designing the crown data based on the abutment on the three-dimensional image; according to semi-sintered zirconia The contraction rate of the crown data is enlarged in the same proportion, and the crown layout is performed in the semi-sintered zirconia matrix according to the enlarged data; the positioning rod 2 is designed on a single crown 1 (such as figure 1 (Shown), according to the typeset single crown data with positioning rods, the single inner crown with positioning rods is processed by numerical control processing equipment; the single inner crown is sintered at high temperature and then piled and sintered; using a three-dimensional scanner Scan the sintered single inner crown to obtain the single blank data, and use the CNC polishing equipment to polish the blank with the connecting rod

[0025] Embodiment 2: A method for producing multiple crowns using zirconia, including: scanning a tooth model with a three-dimensional scanner to obtain a virtual three-dimensional image, designing the crown data based on the abutment on the three-dimensional image; The shrinkage rate of zirconium enlarges the crown data in the same proportion, and according to the enlarged data, the crown layout is performed on the semi-sintered zirconia matrix; during layout, positioning rods 2 are designed on the connecting rods 3 of multiple crowns 1 (such as figure 2 with image 3 (Shown), according to the typeset data of multiple crowns with positioning rods, the multiple inner crowns with positioning rods are processed by numerical control processing equipment; the multiple inner crowns are sintered at high temperature and then piled and sintered; using a three-dimensional scanner Scan the sintered multiple inner crowns to obtain multiple blank data, and use CNC grinding equipment to polish
