Problems solved by technology

[0003] Nowadays, CAD / CAM technology has been promoted and popularized in the dental industry, but the resin engraving blocks used in the existing CAD / CAM technology in the dental industry are all single-color, and can only be carved after ordinary single-color dentures. The traditional denture base production process cannot completely change the status quo of denture base production

Abstract

The invention relates to a multi-layer-color denture and base integrated carving block as well as manufacturing and use methods thereof. The carving block comprises two resin layers with a lower base layer and an upper denture layer. The manufacturing method comprises the following steps: performing color matching on the base layer and the denture layer, performing injection molding, and trimming and forming. According to the method, a user can be freed from a heavy and harmful conventional denture base manufacturing process, and a layer-rich denture and base integrated product conforming to a natural tooth form can be manufactured at the same time in a one-time manufacturing process through a CAD/CAM (computer-aided design/computer-aided manufacturing) technology in the existing dental industry.

Description

technical field [0001] The invention relates to a denture and a manufacturing method thereof, in particular to a multi-layer colored denture and a base integrally formed engraving block and a manufacturing and using method thereof. Background technique [0002] With the continuous development of social development level, people pay more and more attention to oral health, so the demand for denture base is also increasing. The production of traditional denture bases requires raw materials such as model wax, gypsum, resin teeth or porcelain teeth, and base resins, which are manually completed by technicians through a series of cumbersome processes. The production of a pair of base needs the cooperation of many technicians to complete, and the production cycle is longer. And it has a great relationship with the proficiency of technicians, and there are many uncontrollable human factors. [0003] Nowadays, CAD / CAM technology has been promoted and popularized in the dental indus...
