Problems solved by technology

[0003] However, the denture base with metal mesh processed in the prior art needs to make the metal mesh through CAD / CAM technology first, and then use the traditional method to attach the denture and base resin to the outside of the metal mesh. The process is complicated and easy to fail. The prepared base affects the overall aesthetics of the base due to the color of the metal mesh

Abstract

The invention discloses a three-dimensional metal mesh and denture integrally molded carving block. The carving block comprises a denture resin main body and a three-dimensional structure metal mesh which is embedded in the denture resin main body, wherein the denture resin main body is prepared from the following components in percentage by weight: 60.0 percent of polymethyl methacrylate-acrylic acid copolymer, 36.0 percent of polymethyl methacrylate and 4.0 percent of pigment. When the three-dimensional metal mesh and denture integrally molded carving block is used, the denture finished product containing the metal mesh can be manufactured only by once CAD / CAM technology, so that consumption of time and materials can be greatly reduced, and the attractive appearance and impact resistance of the denture can be improved.

Description

technical field [0001] The invention relates to the field of denture bases, in particular to a carving block integrally formed with a three-dimensional metal mesh and a base and a preparation method thereof. Background technique [0002] Denture bases with built-in metal mesh have always been popular with users because of their high strength. [0003] However, the denture base with metal mesh processed in the prior art needs to make the metal mesh through CAD / CAM technology first, and then use the traditional method to attach the denture and base resin to the outside of the metal mesh. The process is complicated and easy to fail. The prepared base affects the overall aesthetics of the base due to the color of the metal mesh. Contents of the invention [0004] In view of this, the purpose of the present invention is to address the above shortcomings, to provide a three-dimensional metal mesh and base integrally formed engraving block, when the engraving block is used, only...
