Problems solved by technology

[0002] The prior art uses self-setting plastic to manually shape the wax-type of the three-dimensional bracket of the complete denture, and uses the embedded casting technology to manufacture it. The disadvantage is that the denture plastic has material shrinkage during molding, which leads to denture deformation, which takes up to two days, and there are Disadvantages of casting failure and metal shrinkage cavities

Abstract

The invention provides a digital manufacturing method of a three-dimensional bracket for a complete denture, which scans a complete denture model based on a scanning device to obtain three-dimensional data of the model, and at the same time, scans the artificial tooth part and the base part related to the denture model to obtain the shape of the denture Three-dimensional data; based on the design software, and according to the obtained three-dimensional data of the model and the three-dimensional data of the shape of the denture, the base part of the full-mouth three-dimensional bracket is determined; based on the design software, the determined base part of the full-mouth three-dimensional bracket is merged with the artificial part, And each artificial tooth of the combined artificial tooth part is connected with the corresponding base to form a whole three-dimensional bracket; the whole three-dimensional bracket is manufactured by using laser sintering technology. It replaces the traditional method of manufacturing denture brackets with manual wax pattern and casting technology, which has high technical precision and high speed, simplifies the manufacturing process of three-dimensional brackets, reduces manufacturing difficulty, and improves the precision and metal quality of denture brackets.

Description

technical field [0001] The invention relates to the technical field of design and manufacture, in particular to a digital manufacturing method of a three-dimensional bracket for a complete denture. Background technique [0002] The prior art uses self-setting plastic to manually shape the wax-type of the three-dimensional bracket of the complete denture, and uses the embedded casting technology to manufacture it. The disadvantage is that the denture plastic has material shrinkage during molding, which leads to denture deformation, which takes up to two days, and there are Disadvantages of casting failure and metal shrinkage cavities. This technology uses computer software for digital design, which is fast and the data is not deformed. Laser sintering technology is used to manufacture three-dimensional brackets for full dentures, and there are no defects inside the denture metal. Therefore, a digital manufacturing method of three-dimensional brackets for complete dentures is...
