Description

Teeth Impression Acquisition Tray

The present invention relates to a tray for impression acquisition, and more particularly, to a impression impression tray (Teeth Impression Acquisition Tray) for taking an impression in the oral cavity of a dental patient to produce a prosthesis.

In general, in order to produce a dental prosthesis of a dental patient, it is necessary to obtain a dental impression in the oral cavity of the patient, wherein the impression acquisition device used is called a tray or an impression acquisition tray.

The structure of the conventional tooth impression collecting tray consists of a concave structure that can hold an impression agent and a handle fixed to the structure to obtain an internal impression structure of the oral cavity of a dental patient to which the dental prosthesis is to be mounted. The constituent material is mainly a metal material.

However, the above-described conventional tray has the following disadvantages.

While the forms of dental diseases are very diverse, the dental prosthesis manufacturing apparatus for treating them is very simple and therefore has a disadvantage in that it is not easy to produce sufficient dental care and proper dental prostheses.

For example, some dental patients have no teeth at all, and some have to wear a partial dental prosthesis, whereas a dental prosthesis manufacturing apparatus for this has a very simple problem.

In addition, even among dental patients, there are infants and children, and even adults have to produce various types of dental prostheses, there is a drawback that the impression acquisition tray is very uniform and does not perform sufficient and proper dental care.

The purpose of the present invention for solving the above problems is to provide a dental impression acquisition tray that allows not only to produce a variety of dental prostheses, but also to allow the doctor to choose according to his treatment style.
