Description

technical field [0001] The invention relates to the field of denture manufacturing devices, in particular to a multifunctional final impression device, a method of use and a method for manufacturing a digital complete denture. Background technique [0002] At present, with the aging of the population, the number of edentulous patients and edentulous patients is also increasing. Measure the patient's median position and occlusal plane to guide the arrangement position of the restored artificial teeth. When the final impression is made, the traditional edentulous final impression tray is based on the doctor's intraoral impression made by the patient and poured plaster. The plastic base made by the model is complicated to make and inconvenient to use, and the digital final impression tray made by computer-aided technology has only one function, and it is not easy to make accurate impressions and the relationship between the upper and lower jaws. Take the tray of the final impr...

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
