Description

[Detailed description of the invention] [Technical field of the invention] The present invention is a model for removing tartar and smoothing the root surface, which is extremely useful for dental students to acquire techniques for removing tartar and smoothing the root surface during clinical training. Regarding.

[Technical background of the invention] Deposition of tartar is seen in almost all cases of gingivitis and periodontitis, and therefore, removal of tartar and smoothing of the root surface in dental treatment are essential for the treatment and prevention of periodontal disease. This is a basic treatment that cannot be done. Therefore, dental students aiming to become clinical dentists in the future,
Learning this technique is extremely important.

However, in order to acquire such techniques, it is necessary to practice over and over again under conditions similar to actual treatment, but in reality, there are no suitable practice models available. The reality is that it is almost never done.

[Purpose of the invention] The present invention was developed in response to these circumstances, and is a method for removing tartar and root roots that uses teeth with an assumed tartar layer in actual treatment in clinical training, etc., and that can be used repeatedly. The purpose is to provide a model for surface smoothing.

[Summary of the invention] That is, the model for removing tartar and smoothing the root surface according to the invention includes a base plate corresponding to the upper jaw or the lower jaw, and rows arranged on the upper surface of the base plate at positions approximately corresponding to the row of teeth. a plurality of tooth simulating protrusions, each of which is removably provided on the surface of the tooth, the tooth simulating protrusions are composed of a sphere portion and a shaft portion covered almost entirely with a colored enamel layer, and , characterized in that it is removably attached to the substrate via the shaft portion.

[Embodiment of the invention] The details of the invention will be explained below with reference to drawings showing one embodiment of the invention.

FIG. 1 is a perspective view showing an example of a model for removing tartar and smoothing a root surface according to the present invention, and FIG. 2 is a sectional view of a tooth simulating projection.

In the figure, reference numeral 1 indicates a base corresponding to the lower jaw (or upper jaw), and 2 indicates a simulated tooth body attached to the upper surface of this base 1. This simulated tooth body 2 consists of a hard spherical simulated tooth part 21 and an insertion protrusion part 22 having a stepped part provided at the bottom thereof, and is placed on the upper surface of the base 1 in a state that is approximately aligned with the tooth row. The 15 pieces are arranged in a semicircular pattern, looking like teeth. The size of the hard spherical simulated teeth 21 is such that the diameter increases from the front, which is assumed to be the front teeth, to the rear, which is assumed to be the back teeth. preferable.

Although illustration of each of these simulated tooth bodies 2 and the base 1 is omitted, the insertion protrusion 22 of each simulated tooth body 2 is inserted through a shaft insertion hole drilled in the base 1 up to the step thereof. It is removably fixed using a fixing tool such as a fixing nut.

Therefore, the hard spherical simulated tooth part 21 of the simulated tooth body 2
A simulated tartar layer 3 is formed on the surface and the upper surface of the insertion protrusion 22 . This simulated tartar layer 3
It consists of an enamel layer, a resin containing an inorganic material such as titanium, etc., and colored enamel is particularly preferred because it can be easily distinguished from the inner core.

The material for forming the base 1 and the simulated tooth body 2 is not particularly limited, but as the base 1, a metal plate, a plastic board, a wooden board, etc. can be used as appropriate, and for example, a vinyl chloride resin board etc. are suitable. Further, the simulated tooth body 2 is not particularly limited as long as it is spherical or polygonal and can easily be likened to a tooth, and the simulated tartar layer 3 is easily formed, such as metal, hard plastic, ceramic, ceramic molded body, etc. can be used.

The dental scale removal and root surface smoothing model of the present invention configured as described above is used, for example, in the following clinical practice to simulate actual treatment.

That is, first, the simulated tartar layer 3 corresponding to tartar on the surface of the simulated tooth body 2 is scratched and removed using a manual scaler or the like which is generally used as a tartar removal tool. Since the simulated tartar layer 3 is colored,
It is easy to judge whether the treatment has been completed or not. Next, after polishing the surface to make it smooth, cleaning is performed to remove simulated tartar pieces and the like.

In order to use the dental calculus removal and root surface smoothing model of the present invention that was used in this way again for practical training, after the practical training was completed, the simulated tooth body 2 was removed from the base 1 and a virtual dental calculus material such as enamel was applied. After forming the simulated tartar layer 3, it is assembled again.

As described above, the model for removing tartar and smoothing the root surface of the present invention can be repeatedly used in one cycle of virtual tartar layer removal and virtual tartar layer re-formation that simulates dental tartar in training.

In addition, in the above embodiment, the simulated tooth body 2 and the base 1 were formed separately and made detachable, but the present invention is not necessarily limited to this, and the base 1 and the simulated tooth body 2 are integrally formed. may be formed.

[Effects of the invention] As is clear from the above embodiments, according to the model for removing tartar and root surface smoothing of the present invention, it is possible to remove tartar on the surface of the protrusions provided in a shape close to the actual teeth and dentition. Since we have created a simulated tartar layer that can be re-formed, the condition is close to that of the actual treatment, and it can be used repeatedly, making it possible to fully master the techniques of tartar removal and root surface smoothing treatment. . Also,
Since the simulated tooth body is removably attached to the base,
After completing training such as removing tartar, the simulated tooth body can be removed from the base, a virtual tartar material such as enamel is applied to form a simulated tartar layer, and then it can be reassembled. Furthermore, since the simulated tartar layer is colored,
During training such as tartar removal, it is possible to easily judge whether the treatment has been completed perfectly.
