Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary tools, and more specifically to a tooth color comparison plate. Background Art

[0002] With the continuous improvement of people's living standards, people pay more and more attention to the protection and repair of teeth. Dental veneers are a more popular method of tooth restoration in recent years. Dental veneer restoration is to stick a layer of material close to the color of normal teeth on the surface of discolored or defective teeth to achieve the effect of whitening or repairing.

[0003] Before doctors perform veneer operations on teeth that need to be repaired in patients' mouths, they need to first determine the color of the veneers, and then simulate the restoration effects after veneer placement through data processing, and show the restoration effects to patients, so that patients can confirm the veneers, helping the color of the teeth to be closer to the color of real teeth and ensuring their aesthetics.

[0004] Currently, the existing tooth color comparison plate connecting piece adopts circular through holes to install the removable denture, but this installation method is not stable and it is easy to cause the removable denture to rotate and move during use, making it difficult to correctly identify the color of the removable denture, which interferes with the doctor's identification and judgment of the color of the patient's original teeth.

[0005] Therefore, providing a tooth shade plate with a reasonable structure, firm installation and long service life is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model aims to provide a tooth shade guide with a reasonable structure and firm installation.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions, which mainly include:

[0008] A tooth colorimetric plate comprises a tooth model, a connecting piece and a colorimetric plate holder, wherein the tooth model is mounted on the colorimetric plate holder through the connecting piece;

[0009] Also included are:

[0010] A column, a polygonal column is provided on the back of the tooth model, and the tooth model and the polygonal column are an integrated structure;

[0011] A polygonal through hole is provided on the connecting plate, and the polygonal through hole is engaged with the polygonal column to limit the longitudinal position of the tooth model.

[0012] Preferably, a nail rod is installed on the polygonal column, and the nail rod passes through the polygonal through hole and is welded to the connecting plate by ultrasonic hot-melt welding, so as to limit the lateral position of the tooth model.

[0013] Preferably, the top of the tooth model is a crown, and the bottom is a root. The tooth model has a conical structure, and the diameter of the crown is greater than the diameter of the root.

[0014] Preferably, the tooth model is divided into a filling layer and an oxidation-resistant layer, and the oxidation-resistant layer is wrapped around the outside of the filling layer.

[0015] Preferably, the column is a hexagonal structure.

[0016] Preferably, the tooth model is divided into 27 color levels.

[0017] It can be seen from the above technical solution that compared with the prior art, the utility model combines the filling layer and the oxidation-resistant layer together, thereby improving the oxidation resistance of the tooth model. A column is installed under the tooth model, which is limitedly engaged with the polygonal through hole on the connecting plate, which can effectively prevent the rotation of the tooth model, reduce the difficulty of identifying teeth on the colorimetric plate, and improve the doctor's recognition of the tooth model. In addition, the tooth model adopts 27 color levels, the color distinction is more refined, the use process is more convenient, the stability of the tooth model on the colorimetric plate is improved, and it is easy to carry, which solves the problem of instability and low color recognition of the existing tooth model after installation.
