Tool for obtaining dental occlusion in patient with edentulous jaw

Abstract

In the present invention, a tool for obtaining dental occlusion in a patient with an edentulous jaw is provided with: a main body (1) that has a rear-side curved plate (1a) which is positioned on the buccal side of the maxillary and mandibular residual ridges in the mouth cavity of a patient with an edentulous jaw, a front-side curved plate (1b) which is positioned on the extraoral-side of the upper and lower lips, a joining section (1c) for joining respective vertically intermediate sections of the rear-side curved plate (1a) and the front-side curved plate (1b), and a through hole (1d) formed penetrating through the rear-side curved plate (1a), the front-side curved plate (1b), and the joining section (1c), the main body being positioned and fixed in a state in which each of the upper and lower lips holds the joining section (1c); and an adjusting shaft (2) that is inserted into the through hole (1d) and that has a tongue support section (2a), one end of which projects out to the extraoral-side from the middle of the space between the upper and lower lips, and the other end of which retains the tip of the tongue inside the mouth cavity, the adjusting shaft (2) being for adjusting the position of the tongue support section (2a) and suppressing the movement of the tongue when dental occlusion is being obtained.

Description

Technical field [0001] The invention relates to a bite recorder for patients with edentulous jaws. Background technique [0002] When making a complete denture for an edentulous patient, generally speaking, the impression of the upper and lower alveolar ridges is first obtained, and then a plaster model of the oral cavity is made based on the impression. [0003] In addition, in order to determine the occlusal position, the wax ridge made on the plaster model is used to record the occlusion, and then the plaster model is installed on the articulator by a dental technician, and a complete denture is made for edentulous patients by common methods. [0004] The occlusal recording performed in the above manner requires proficiency and experience. Depending on the technician, there will be big differences. If the occlusal recording cannot be performed correctly, the product provided to the patient may not meet the requirements, and the occlusal recording has to be reworked. Make new comp...

AI Technical Summary

Problems solved by technology

[0006] In the above-mentioned method proposal, in order to correctly convey the median position to the dental technician, the dentist installs a sample tooth (or an assembly jig for denture production) on the wax ridge recorded by the occlusal, as a mark of the median position, etc. (refer to the patent document 1 for example figure 2 ), while the occlusal recording itself still adopts the traditional method (refer to paragraphs 0016 and 0017 of Patent Document 1, for example), and does not take any solution to the problem that it is difficult to correctly determine the occlusal position
