Embodiment Construction

[0020] Below in conjunction with specific embodiment the present invention is described in further detail, please refer to figure 1 .

[0021] In the field of orthodontic correction of dento-jaw deformity, the dento-jaw model used in the pressure film forming process of the invisible aligner can adopt the processing technology of the present invention.

[0022] Including dental model scanning process and 3D printing process.

[0023] Dental model scanning process. The pretreated dental model is scanned by scanning equipment, and the scanning method can be semi-automatic scanning or manual scanning.

[0024] 3D printing process. Obtain the three-dimensional digital model of the scanned dental model on the computer client, and then use the following steps to perform pre-printing processing and printing.

[0025] 1) Import digital model: "import" the 3D data of the dental model to be designed into Magics reverse engineering software, and store it in STL file format;

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...
