3D printed dental cast processing technology

Abstract

The invention discloses a 3D printed dental cast processing technology which sequentially comprises a dental cast scanning step and a 3D printing step, wherein the 3D printing step sequentially comprises the following steps: 1) importing a digital model; 2) attenuating a hook face of the model; 3) repairing bad edges of the model; 4) hollowing the model; 5) cutting a gingiva substrate; and 6) 3D printing moulding. The 3D printed dental cast processing technology disclosed by the invention is used for changing the characteristic that photosensitive resin dental models obtained by virtue of a 3D printing moulding machine are solid models, saving a lot of photosensitive resin raw materials, reducing the printing and processing areas, shortening the printing moulding time, improving the processing efficiency and lowering the production cost and the transport cost.

Description

technical field [0001] The invention relates to the technical field of dental instruments, more specifically, to a 3D printing dental model processing technology. Background technique [0002] In recent years, orthodontic invisible correction technology has gradually developed and matured in my country. With the interdisciplinary collaboration between orthodontists and computer software engineers in some countries such as the United States and China, CAD / CAM technology and advanced production methods are used to produce a personalized polymer plastic appliance. The appliance can generate a certain amount of orthodontic force to make the teeth move gradually and slowly, thus overcoming the shortcomings of traditional orthodontic methods. The method is to use a 3D printing machine to print out the jaw model in the orthodontic process, and then use a positive pressure laminating machine to press and process the invisible aligner on the jaw model. However, in the prior art, th...

Problems solved by technology

However, in the prior art, the photosensitive resin tooth and jaw models of the pressed invisible aligners obtained by the 3D printing machine are all solid models

According to the principle that 3D printing is layer-by-layer stacking and stacking, the solid model takes a long time to print and form, which affects the processing efficiency; it also consumes a lot of photosensitive resin raw materials, which to a certain extent causes waste of raw materials and reduces production costs. High; its quality is heavier than the hollow model, and it costs more when the model is transported in batches
