Description

Technical Field

[0001] The utility model belongs to the technical field of oral models, and in particular relates to an improved periodontal disease model for accurate periodontal pocket probing. Background Art

[0002] Probing is a diagnostic technique used by dentists during periodontal examinations. During probing, your dentist will gently insert a probe into the space between the gums and teeth, known as the gingival sulcus or periodontal pocket, to measure its depth and assess for inflammation, such as redness, swelling, bleeding or pus, and alveolar bone loss. These are important indicators of periodontal diseases, such as gingivitis and periodontitis.

[0003] Since beginners lack systematic probing training, directly probing patients can easily lead to a series of mistakes. Therefore, there is an urgent need for a model for periodontal disease probing so that beginners can receive systematic probing training and master the skill of periodontal probing. Utility Model Content

[0004] In order to solve the above problems in the prior art, an improved periodontal disease model for accurate periodontal pocket probing is provided.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The utility model proposes an improved periodontal disease model for accurate periodontal pocket probing, comprising:

[0007] Artificial teeth;

[0008] An artificial alveolar bone, wherein the inner side of the artificial alveolar bone has an alveolar socket;

[0009] Artificial gums, the artificial gums being attached to the surface of the artificial alveolar bone;

[0010] Among them, the bottom of the artificial tooth is fixed in the alveolar socket, and pits of different heights are opened on both sides of the alveolar socket. The artificial alveolar bone between the bottoms of the two pits is attached to the outer surface of the artificial tooth, and the artificial alveolar bone above the two pits gradually moves away from the outer surface of the artificial tooth to form an artificial periodontal pocket.

[0011] Preferably, it also includes:

[0012] A threaded hole opened at the bottom of the artificial tooth;

[0013] A through hole, the through hole passes through the artificial alveolar bone and the artificial gingiva and corresponds to the threaded hole;

[0020] Preferably, the artificial tooth is made of hard plastic and is white in color.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The utility model adopts split-type artificial teeth and artificial alveolar bones to connect, which is convenient for probing different tooth shapes. Pits of different heights are opened on both sides of the artificial alveolar bones, and the distance between the pits and the artificial teeth forms an artificial periodontal pocket. Through pits of different depths, the appearance of different degrees of periodontal disease can be simulated more intuitively. At the same time, artificial gums are attached to the upper surface of the artificial alveolar bones to further simulate the situation of artificial periodontal disease and avoid the bottom of the artificial periodontal pocket from directly contacting the artificial alveolar bones during periodontal probing.

A threaded hole is provided at the bottom of the artificial tooth, and a through hole corresponding to the threaded hole is provided at the bottom of the artificial alveolar bone.

At the same time, a screw head slot is provided at the bottom of the artificial alveolar bone, and the head of the fixing bolt is embedded in the screw head slot, so that the bottom surface of the artificial alveolar bone is kept at a horizontal plane, thereby increasing the stability of the artificial alveolar bone after placement.

When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0032] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0033] like Figure 1 As shown, this embodiment proposes an improved periodontal disease model for accurate periodontal pocket probing, comprising:

[0034] Artificial tooth 1 is made of hard plastic and is white in color. Its appearance can be any permanent human tooth, achieving a high degree of simulation and being closer to the appearance of real teeth.

[0035] The artificial alveolar bone 3 has an alveolar socket 4 which is sunken downward in the middle of the inner side of the artificial alveolar bone 3, and alveolar ridges 11 are provided on the tops of both sides of the artificial alveolar bone 3. The upper surface of the alveolar ridges 11 is a smooth ellipse, which further simulates the shape of the real artificial alveolar bone 3. In this embodiment, the artificial alveolar bone 3 is made of hard plastic material and is white in color, which makes it look more realistic.

[0036] Artificial gums 2 are attached to the surface of artificial alveolar bone 3. In this embodiment, artificial gums 2 are made of thin sheets of silicone material, and the color is light red. The artificial gums 2 are attached and fixed to the surface of artificial alveolar bone 3 by adhesive.

[0037] Among them, the bottom of the artificial tooth 1 is fixed in the socket of the artificial tooth 1, and pits 5 of different heights are opened on both sides of the socket of the artificial tooth 1. The artificial alveolar bone 3 between the bottoms of the two pits 5 and the artificial gum 2 above it are attached to the outer surface of the artificial tooth 1, and the artificial alveolar bone 3 and the artificial gum 2 in the upper part of the two pits 5 gradually move away from the outer surface of the artificial tooth 1 to form an artificial periodontal pocket 6.

[0038] This design allows for a more intuitive observation of periodontal disease. When the oral cavity is healthy, the gums fit the bottom of the teeth. As the periodontal disease progresses, the periodontal pockets become deeper and deeper, further damaging the supporting tissues around the teeth. The periodontal pockets of mild periodontal disease are generally about 3 to 4 mm deep; the periodontal pockets of moderate periodontal disease are generally about 4 to 6 mm deep; the periodontal pockets of severe periodontal disease are generally more than 6 mm deep. In this solution, in order to further simulate the different degrees of periodontal disease, two groups of pits 5 of different heights are provided, and an artificial periodontal pocket 6 is formed between the top of the pit 5 and the artificial tooth 1. The height of the pit 5 is different, and the depth of the artificial periodontal pocket 6 also changes accordingly, so as to further and more intuitively feel the appearance of different degrees of periodontal disease.

[0039] At the same time, the artificial gingiva 2 made of silicone material is attached and fixed to the upper surface of the artificial alveolar bone 3, so that the bottom of the artificial periodontal pocket 6 will not directly contact the artificial alveolar bone 3 during periodontal probing, but will have a soft touch, highly simulating the real clinical state.

[0040] In the market, the artificial teeth 1 and the artificial gums 2 are generally fixed by bonding. This bonding method is prone to loosening and falling off after a long time. To solve this problem, this solution uses screw tightening to fix, which specifically includes:

[0041] A threaded hole 7 is provided at the bottom of the artificial tooth 1. Specifically, the threaded hole 7 is provided at the center of the bottom of the artificial tooth 1;

[0042] A through hole 8, which passes through the artificial alveolar bone 3 and the artificial gingiva 2 and is arranged corresponding to the threaded hole 7;

[0043] The fixing screw 9 passes through the through hole 8 and is threadedly connected with the threaded hole 7.

[0044] When fixing the artificial tooth 1, align the threaded hole 7 in the artificial tooth 1 with the through hole 8 in the artificial alveolar bone 3. After alignment, use the fixing screw 9 to first penetrate the through hole 8, and then screw the fixing screw 9. The fixing screw 9 will cooperate with the threaded hole 7 to fix it, thereby achieving the purpose of stabilizing the artificial tooth 1 on the artificial alveolar bone 3.

[0045] Furthermore, a screw head slot 10 is opened at the bottom of the through hole 8. After the retaining screw 9 is matched with the threaded hole 7, the head of the retaining screw 9 is embedded in the screw head slot 10, so that the bottom surface of the artificial alveolar bone 3 remains in a horizontal plane, thereby increasing the stability of the artificial alveolar bone 3 after placement.

[0046] How it works:

[0047] During assembly, the artificial tooth 1 is clamped in the alveolar socket 4 in the artificial alveolar bone 3, and the threaded hole 7 is aligned with the through hole 8; then the threaded end of the fixing screw 9 is passed through the through hole 8, and the fixing screw 9 is screwed after passing through the through hole 8. The fixing screw 9 cooperates with the threaded hole 7 and is fed in the threaded hole 7 until the head of the fixing screw 9 is embedded in the screw head slot 10, so that the bottom surface of the artificial tooth 1 socket remains horizontal.

[0048] When demonstration is needed, the artificial alveolar bone 3 and the artificial tooth 1 connected thereto are placed on a display platform so that an observer can further observe the severity of the periodontal disease, which is convenient for explanation.

[0049] When it is necessary to teach periodontal disease, especially when teaching periodontal probing, the periodontal probe can be used to directly contact the artificial gingiva 2. The artificial gingiva 2 has a soft touch and highly simulates the real clinical state.

[0050] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
