Complete denture generation method, electronic equipment and computer readable storage medium
The invention provides a complete denture generation method, electronic equipment and a computer readable storage medium, and relates to the technical field of digital oral cavities. The method comprises the following steps: acquiring an edentulous jaw three-dimensional model, face scanning data and oral cavity scanning data of a user; extracting upper and lower jaw feature information of the edentulous jaw three-dimensional model; based on the upper and lower jaw feature information of the edentulous jaw three-dimensional model, obtaining a target natural dentition model from a natural dentition database; and based on the face scanning data and the oral cavity scanning data, calibrating the target natural dentition model to obtain a complete denture three-dimensional model. The corresponding dentition is matched in the natural dentition database, and the complete denture is manufactured on the basis of the matched and screened dentition, so that compared with a traditional complete denture manufacturing method, the complete denture manufacturing method is quicker and more accurate, clinical operation links are reduced, the manufacturing period is shortened, and the manufacturing efficiency is improved. And the manufacturing efficiency of the complete denture and the fitness of the generated complete denture and a user are remarkably improved.

Mechanical structure of complete denture
The utility model relates to the technical field of complete dentures, in particular to a mechanical structure of a complete denture, the mechanical structure comprises a base and a plurality of denture bodies, a connecting assembly is arranged on the base and the denture bodies, the connecting assembly comprises a plurality of fixing grooves formed in the upper surface of the base, the bottom ends of the denture bodies are fixedly connected with fixing rods, and the fixing rods are fixedly connected with the base. Through cooperative arrangement of the fixing grooves, the fixing rods, the insertion rods and other structures, when the denture is used, the insertion rods are contracted into the containing holes by pulling the pull rods, then the fixing rods are inserted into the fixing grooves respectively, the denture body is installed on the base plate, then the pull rods are loosened, and the denture body is fixed to the base plate through the insertion rods. When one or more false tooth bodies are damaged, the false tooth bodies can be replaced only by pulling the pull rod and pulling up the false tooth bodies upwards, and the problem that resources and money are wasted due to the fact that the complete false tooth needs to be replaced is avoided as much as possible.
