DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(Example 1-1) The toothbrushing learning apparatus of the present invention includes a lower tooth model 100 including a lower alveolar bone 120, a lower tooth 130 and a lower gingival section 140 in a lower frame 110, An upper tooth model 200 including an upper alveolar bone 220, an upper tooth 230 and an upper gingival section 240 on the upper alveolar bone 210 and a connecting part 300 connecting the lower frame and the upper frame.

The toothbrush learning device is a model of only the tooth structure of the human body. The tooth structure is inserted into the upper alveolar bone and the lower alveolar bone based on the upper alveolar bone formed on the skull and the lower alveolar bone formed on the jaw bone. Each alveolar bone and a portion of each tooth is covered with a gingival portion.

Thus, in Example 1-1, the upper frame 210 is formed instead of the skull, the upper alveolar bone is formed in the upper frame, the upper teeth are formed in the upper alveolar bone, and a part of the upper alveolar bone and the upper teeth are covered with the upper gingiva . A lower frame 110 is formed in place of the jawbone, a lower alveolar bone is formed in a lower frame, a lower tooth is formed in a lower alveolar bone, and a lower alveolar bone and a part of a lower tooth are covered with a lower gingival section. The upper frame and the lower frame are joined to each other as a connecting portion.

Example 1-2 In the toothless learning apparatus of Example 1-1, a permanent tooth model 150 formed on the lower alveolar bone and formed in a plurality of teeth is included.

In Example 1-2, a permanent tooth model formed on the alveolar bone is included to reproduce the shape of the permanent teeth. The permanent teeth are formed under each tooth.

(Example 2-1) In the toothbrush learning apparatus of Example 1-1, the gingival portion is formed of a soft material, the alveolar bone is formed of a hard material, the alveolar bone and the gingival portion include a plurality of coupling means 400 .

The tooth fountain should recognize the external and internal structure of the tooth structure to the learners. Thus, the gingival portion is formed in a detachable structure. The gingival portion and the alveolar bone form a coupling means for gingival detachment. That is, the external shape of the tooth structure is the state in which the gingival section is attached, and the internal shape of the tooth structure is the state in which the gingival section is detached. The gingiva should be of a soft material as it should show similar characteristics to the gums. The alveolar bone and teeth are made of a hard material since they must be simulated with bone-like materials. During tooth training, the gingival material should be deformable so that the toothbrush enters between the teeth and gingiva.

(Example 2-2) In the toothbrush learning apparatus of Example 2-1, the soft material includes one selected from silicone rubber, urethane rubber, and acrylic rubber.

The deformable gingival portion is made of rubber. As the rubber material, it is preferable to use a synthetic rubber, such as silicone rubber, urethane rubber, or acrylic rubber, and substitute it with a material having the same purpose and effect. In addition, the gingival portion may be formed of a transparent material.

(Example 2-3) In the toothbrush learning apparatus of Example 2-1, the hard material is at least one selected from the group consisting of polystyrene (PS), polypropylene (PP), AS resin, ABS resin, PMMA, PC), polyamide (PA), polyacetal (POM), fluorocarbon resin (PVDF), and polyethylene (PET).

The alveolar bone model should have characteristics similar to bone. Therefore, it is formed of a usual polymer material in view of workability and weight, and is preferably made of the material of Example 2-3. In addition, ceramics and other materials can be substituted for materials of equivalent purpose and effect.

Therefore, protrusions are formed inside the gingival portion of the soft material, and grooves are formed in the alveolar bone. The protrusion is elastically engaged in the process of coupling the protrusion to the groove, so that the protrusion is not easily detached. On the contrary, it forms a protrusion on the alveolar bone, a groove can be formed on the gingival section, and a groove and a protrusion can be formed on the alveolar bone and the gingival section.

In Example 2-4, the protrusion is formed only in the gingival portion. In Example 2-5, the protrusion is formed only in the alveolar bone. In Example 2-6, the protrusion is formed in the gingival portion and alveolar bone.
