Abstract

The invention discloses a method for 3D printing of personalized dentures. The method comprises the following steps of 1, obtaining tooth data and converting the tooth data into a tooth 3D model; 2, adopting a supporting structure for supporting on a workbench according to the contour of the tooth surface, adopting a pointed cone supporting column for supporting on the outer concave face of the tooth 3D model, adopting a cylindrical supporting column for supporting on the inner concave face of the tooth 3D model, and adopting a tooth-shaped grid for supporting on the plane of the tooth 3D model; 3, printing the tooth 3D model on the supporting structure by adopting a 3D printer; and 4, removing the supporting structure on the surface of the tooth 3D model. The invention aims at providing the method for the 3D printing of the personalized dentures, which can conveniently remove the model support and improve the denture surface processing quality.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a method for 3D printing personalized dentures. Background technique [0002] Dentures are "false teeth" that people often say, and the meaning of dentures refers to the teeth that perform "duties" for human beings. In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth. Dentures are divided into two types: removable and fixed. Fixed dentures cannot be taken and worn by patients themselves, while removable dentures can be taken and worn by patients conveniently. Now, 3D printing technology has been widely used in the manufacture of dentures. It is a rapid prototyping process that uses layers to build up three-dimensional models. Its operation process is similar to that of traditional printers, except that traditional printers print ink onto paper. In essence, two-dimensional plane drawings are formed, whil...
