5) and (3) applying numerical control processing equipment and matched software thereof, and adopting a photocuring printing material to implement false tooth printing and forming so as to finish the manufacture of false teeth.
The light-cured printing material comprises a light-cured resin material of nano ceramics, glass fibers or carbon fibers; the material comprises PMMA material liquid.
The strength and the wear resistance of the photo-curing material are improved by mixing ceramic fillers or glass fibers and carbon fibers in different proportions, and the hardness and the wear resistance of the photo-curing material after printing can be changed by changing the proportion of the fiber fillers.
Color material: the basic material is PMMA, and the polymethyl methacrylate is the basic material, and can be controlled to be tooth white or gingival pink by adjusting the difference of the added pigment. For example: a1, a2, A3; b1, B2 and B3 are common tooth colors; the light pink and the light pink are the colors of the gum; by making the fibrous filler reddish-black, the color of the gingival blood vessel can be simulated in the base portion.
The specific embodiment is as follows:
