Description

[Detailed explanation of the invention] (a) Field of the invention In this invention, a tooth model is made of wax, a combustion core material is embedded in the layers that constitute the tooth tissue, and each layer of the tooth can be identified. For example, by coloring the tooth and longitudinally cutting through the area near where the core material is buried, the colored part of the tooth can be easily seen and confirmed from the outside, and the actual tooth can be seen where each tissue layer is sequentially eroded by the burning of the core material. clarified the progress and approximate phenomena of being attacked by bacteria,
This relates to a tooth model that is intended to be easily embedded.

(b) Background of the invention Until now, various types of education such as the correct way to brush teeth have been carried out in order to protect teeth from cavities and maintain health. However, in reality, there is no tendency for the number of patients with cavities to decrease.Children in particular tend to develop cavities from an early age, so it is important to raise awareness of cavities from an early age, to visually remember how fragile they are, and to develop a mindset of caring for teeth. Although it is necessary, there are no teaching materials that allow students to visually enjoy seeing the state in which teeth are being attacked by bacteria, and to learn about the horrors of it with their own eyes.

(c) Purpose of the invention This invention involves forming a tooth model with wax and burning the upper part of the core material embedded within the tooth tissue, so that as the wax melts, the internal tissue is sequentially dissolved. The current situation is related to a tooth model that can be implanted in a hand-held manner just by looking at its cross-section.

(d) Structure of the device This device is characterized in that a longitudinal tooth model is formed using wax that is identified according to each layer that constitutes the tooth tissue, and a core material for combustion is embedded from the surface of the tooth toward the tooth root. It is a tooth model.

(E) Effect of the invention According to the tooth model of the invention, the wax on the surface is first melted as the core material is ignited and combustion progresses, and then it reaches the dentin and pulp in sequence. Anyone can pick it up and understand it by looking at it.

The situation in which this wax melts is very similar to the state in which teeth are being eroded by bacteria, so you can see for yourself the horror of tooth decay by watching this burning state, and learn for yourself the importance of oral hygiene. Learn about sex without hesitation,
This will minimize the effort required for guidance.

Furthermore, in dental clinics and the like, by arranging each tooth to match the shape of the oral cavity, it can also be used for decoration, and in some cases, it can also be used as a means of illumination in an emergency.

(f) Embodiment of the invention An embodiment of the invention will be described below based on the drawings.

FIG. 1 shows a model 1 of a molar tooth consisting of a crown part 2 and an upper tooth root part 3. The upper end of a combustion core material 5 is protruded from approximately the center of the occlusal surface 4, and the lower part of the core material is a tooth root part. It is buried in the direction.

The tooth model 6 of FIG. 2 according to the present invention is a longitudinal section of the tooth model 1 of the molar tooth in the vicinity of the core material 4, and the surface has an enamel part 1a made of white wax.
The middle layer corresponds to the enamel of an actual tooth, the middle layer is a dentin part 1b made of yellow wax, and corresponds to the dentin of an actual tooth, and the innermost layer is a pulp made of red wax, for example. Part c is also formed to correspond to the pulp of the tooth.

When a dot is placed on the core material 5 of the tooth model 6, as shown in FIG.
Finally, as shown in the imaginary line, it reaches the pulp part 1c.

The situation in which this wax melts is very similar to the state in which an actual tooth is attacked by bacteria, and this state of erosion can be easily disintegrated by simply looking at the cross section of the tooth model 6 that has been ignited. .

Therefore, it is possible to teach children about the structure of teeth using the cross-sectional tooth model 6, and by igniting the core material 5 and watching the wax melt, the child can directly perceive the state in which teeth are being attacked by bacteria. becomes.

In the above embodiment, the molars 1 have been described, but the same applies to premolars and front teeth.
