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

Embodiment 1

[0058] The first embodiment of the present invention is to provide a multifunctional final impression device, the purpose is to quickly and accurately prepare the final impression of an edentulous patient and obtain an accurate median relationship. The doctor's operation, impression taking and determination of the maxillary and mandibular relationship are more accurate, which can effectively improve the quality of the complete denture and ensure the accuracy of the final restoration.

[0059] like Figure 1-2 As shown, in the first aspect, a multifunctional final impression device, which includes an upper jaw base 101, a lower jaw base 102, an upper jaw dentition 201, a lower jaw dentition 202, and an external interface 103, and the bottom of the upper jaw base 101 is provided with There is an upper jaw dentition interface 104 matching the upper jaw dentition 201, and a lower jaw dentition interface 105 matching the lower jaw dentition 202 is provided on the top of the lower j...

Embodiment 2

[0068] A second aspect relates to a method for using a multifunctional final impression device of the first aspect, comprising the following steps:

[0069] Step 1: Install the maxillary dentition 201 and the mandibular dentition 202 in the maxillary base 101 and the mandibular base 102 respectively;

[0070] Step 2: After placing the silicone rubber on the surfaces of the maxillary base 101 and the mandibular base 102, put the maxillary base 101 and the mandibular base 102 into the patient's mouth as a whole, and let the patient occlude the upper and lower jaws to obtain a closed mouth under the occlusal state impression;

[0071] Step 3: Determine whether the occlusal position of the upper and lower dentition is accurate:

[0072] If the occlusal relationship is inaccurate, separate the maxillary dentition 201 and the mandibular dentition 202 from the maxillary base 101 and the mandibular base 102, respectively, so as to leave a dentition gap between the maxillary base 101 ...

Embodiment 3

[0080] like Figure 7-9 As shown in the third aspect, a method for manufacturing a digital complete denture, comprising the following steps:

[0081] Step 1: Use the median jaw tray and the first impression to obtain the full-mouth median relationship;

[0082] Step 2: Scan the initial impression and the median jaw tray or scan the replica plaster model of the initial impression and the median jaw tray, match the data of the initial impression and the median jaw tray, and obtain the initial impression and occlusal relationship data;

[0083] Step 3: Design the multifunctional final impression device of Example 1; the multifunctional final impression device includes an upper jaw base 101, a lower jaw base 102, an upper jaw dentition 201, a lower jaw dentition 202, an upper jaw tracing, a locator 502, and a lower jaw Positioning plate 302, positioning pin 303, 3D printing multifunctional final impression device;

[0084] Step 4: Confirm the relationship between the closed impr...

Abstract

The invention discloses a multifunctional final impression device, a method of use and a method for making a digital complete denture. The multifunctional final impression device comprises an upper jaw base, a lower jaw base, an upper jaw dentition, a lower jaw dentition, an external interface, an upper jaw The bottom of the base is provided with a maxillary dentition interface that matches the maxillary dentition, and the top of the mandibular base is provided with a mandibular dentition interface that matches the mandibular dentition; the bottom of the maxillary base is provided with a tracing board interface, and the maxillary tracing board is connected to the tracing The plate interface is fixed with the maxillary base, a locator is installed on the maxillary tracing board; the top of the mandibular base is provided with a positioning plate interface, the mandibular positioning plate is connected to the positioning plate interface and fixed with the mandibular base, and a positioning pin is installed on the mandibular positioning plate , the mandibular base is connected with the locator through the positioning needle; the external interface is arranged on the front end of the maxillary base, and the external interface is connected to the handle connecting piece or the face bow 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 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...
