Problems solved by technology

[0003] The weight of the traditional dental model is relatively large. In addition, when using the traditional plaster model to make invisible appliances, it is necessary to manually move the position of the crown by heating. This method relies on experience, without quantification and low precision; Faster and more precise than SLA in 3D printing

Embodiment Construction

[0023] Import the three-dimensional data of the oral cavity of the patient with orthodontic treatment into the computer, and design the dental model of the dental treatment process through computer software. The dental model includes the crown and part of the gingiva. The internal space structure is solid, and the crown It is designed as an integral structure with part of the gingiva. The size is 1:1 with the dental data of the patient to be treated.

[0024] The material of the dental jaw of the present invention is a photosensitive resin for 3D printing, that is, epoxy-acrylic resin; a 3D printing molding process of DLP (surface exposure molding) is adopted.

[0025] The present invention is designed and processed by the following methods:

[0026] 1) Import three-dimensional point cloud data: "import" the point cloud data obtained from the scanner, that is, the three-dimensional point cloud data of the jaw model, into reverse engineering software to obtain the jaw model to...

Abstract

The invention provides a rapid manufacturing method of a 3D printing dental orthodontic invisible brace based on the DLP technology. A tooth jaw model comprises a dental crown, gum and a base, wherein the inside of the dental crown, the gum and the base are of solid structures in the spatial structure, and the adopted manufacturing material is a photosensitive resin material used for 3D printing. For a design method of the tooth jaw model, a digital model is designed through a computer, and a processing method of the tooth jaw model is the 3D printing technology of DLP (mask exposure forming), and sequentially comprises the following steps: (1) acquiring and repairing the digital model; (2) carrying out model data stratification; and (3) carrying out 3D printing forming. With the rapid manufacturing method, the surface roughness of the gypsum tooth jaw model prepared by adopting the traditional method is improved, the weight of the tooth jaw model is reduced, the digital model is reserved, so that the storage of data is facilitated, and the production and transportation costs are saved.

Description

technical field [0001] The invention relates to the fields of additive manufacturing and dentistry, in particular to a rapid manufacturing method for 3D printing dental orthodontic invisible braces based on DLP technology. Background technique [0002] In recent years, orthodontic invisible correction technology has gradually developed and matured in my country. With the interdisciplinary cooperation between orthodontists and computer software engineers in some countries such as the United States and China, a personalized polymer plastic appliance is produced by using CAD / CAM technology and advanced production methods. The appliance can generate a certain amount of orthodontic force to move the teeth step by step, thereby overcoming the shortcomings of traditional orthodontic methods. [0003] The weight of the traditional dental model is relatively large. In addition, when using the traditional plaster model to make invisible appliances, it is necessary to manually move th...
