The multifunctional final impression device comprises an upper jaw base, a lower jaw base, an upper jaw dentition, a lower jaw dentition and an external interface, the bottom of the upper jaw base is provided with an upper jaw dentition interface matched with the upper jaw dentition, and the top of the lower jaw base is provided with a lower jaw dentition interface matched with the lower jaw dentition; a tracing plate connector is arranged at the bottom of theupper jaw base, the upper jaw tracing plate is connected into the tracing plate connector to be fixed to the upper jaw base, and a positioner is installed on the upper jaw tracing plate; a positioningplate interface is formed in the top of the lower jaw base, the lower jaw positioning plate is connected into the positioning plate interface to be fixed with the lower jaw base, a positioning needleis mounted on the lower jaw positioning plate, and the lower jaw base is connected with the positioner through the positioning needle; the external connector is arranged at the front end of the upperjaw base and connected with a handle connecting piece or a face arch connecting piece.

Description

technical field [0001] The invention relates to the field of denture manufacturing devices, in particular to a multifunctional final impression device, a use method and a digital complete denture manufacturing method. Background technique [0002] At present, with the aging of the population, the number of patients with edentulous and edentulous jaws is also increasing. In the process of various restorations, with the increase in the number of edentulous, the corresponding positional relationship between the upper and lower jaws of patients is gradually lost. Measure the patient's median position and occlusal plane to guide the arrangement of artificial teeth. When making the final impression, the traditional edentulous final impression tray is based on the doctor's preparation of the patient's oral impression and the perfusion of plaster. The plastic base made of the model is complicated to make and inconvenient to use. However, the digital final impression tray made by c...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing edentulous final impression tray is based on the plastic base made by the doctor to make the impression in the patient's oral cavity and pour the plaster model, which is complicated to make and inconvenient to use. The digital final impression tray made by assistive technology has a single function, and it is difficult to make an accurate impression and the positional relationship between the upper and lower jaws. A multi-functional final impression device is provided, which can quickly and accurately make the final impression of edentulous patients and obtain accurate results. Through the combination of modules, multiple functions can be realized, which greatly simplifies the doctor’s operation, making the model taking and determining the relationship between the upper and lower jaws more accurate, effectively improving the quality of the complete denture, ensuring the accuracy of the final restoration, and solving the current problem. defects caused by technology
