Description

Technical Field

[0001] This utility model relates to the field of oral health education technology, and in particular to a dynamic three-dimensional intraoral model for demonstrating dental and labial space for oral health education. Background Technology

[0002] The structure at the junction of teeth and gums (i.e., the neck region of the tooth) is covered by the lips when the mouth is open, making it more difficult to clean when brushing. Traditional dental education models either completely flip up the lips to expose the junction of teeth and gums, or they lack lip structures, showing only teeth and gums, causing the education process to deviate from reality. Therefore, this invention addresses the shortcomings of existing static models that are detached from clinical scenarios by proposing a dynamic three-dimensional intraoral model for demonstrating the dental and lip space for oral education. Utility Model Content

[0003] The purpose of this invention is to provide a dynamic three-dimensional intraoral model for demonstrating the dental and labial space for oral health education, thereby solving the problems mentioned above.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a dynamic three-dimensional intraoral model for oral health education, comprising a symmetrically distributed maxillary and mandibular structure. The maxillary and mandibular structures are symmetrically positioned at their front ends. Tooth structures are symmetrically distributed on the opposite surfaces of the maxillary and mandibular structures. A gingival structure is positioned between the maxillary and mandibular structures and the tooth structures. The mandibular structure is connected to a tongue structure via a magnetic snap-fit ​​mechanism. A lip structure is positioned at the front end of the tooth structures. The lip structure is integrally formed with a cheek structure, which is connected to the outer walls of the maxillary and mandibular structures via a flexible clip. The maxillary and mandibular structures are connected by an opening and closing mechanism.

[0005] Furthermore, the magnetic snap fastener structure includes a magnetic female snap fastener disposed on the upper end face of the jaw structure, and a magnetic male snap fastener disposed on the lower end face of the tongue structure and cooperating with the magnetic female snap fastener.

[0006] Furthermore, buckles are symmetrically provided on the outer side wall of the upper and lower jaw structure and the inner side wall of the cheek structure, and eyelets matching the buckles are opened at both ends of the flexible strap.

[0007] Furthermore, the upper and lower opening and closing mechanism includes vertically distributed mounting bases. On one side of the mounting base, sector gear two and sector gear one are symmetrically arranged vertically. The teeth of sector gear two and sector gear one mesh together. Connecting rod one is respectively arranged on the outer side wall of the arc surface of sector gear two and sector gear one. The end of connecting rod one is hinged to the opening and closing member. The end of the opening and closing member away from the connecting rod one has a threaded hole. Connecting rod two is hinged to the center of the opening and closing member. The other end of connecting rod two is hinged to the mounting base.

[0008] Furthermore, the second sector gear is rotatably mounted on the mounting base via the second rotating shaft. The first sector gear is key-connected to the first rotating shaft, and the other end of the first rotating shaft passes through the mounting base and is connected to the drive assembly.

[0009] Furthermore, the drive component includes a forward and reverse rotating motor, which is a forward and reverse rotating motor.

[0010] Furthermore, a support base is provided at the lower end of the mounting base.

[0011] Furthermore, the cheek structure, lip structure, and tongue structure are made of flexible materials.

[0012] Furthermore, the cheek structure is made of a flexible, transparent material.

[0016] like Figures 1-4 As shown, a dynamic three-dimensional intraoral model for oral health education, representing a spatial demonstration of the teeth and lips, includes symmetrically distributed maxillary and mandibular structures 6. Mandibular and maxillary structures are symmetrically mounted on the front ends of the maxillary and mandibular structures 6. Tooth structures 3 are symmetrically distributed on the opposite surfaces of the mandibular and maxillary structures. A gingival structure 4 is installed between the mandibular and maxillary structures and the tooth structures 3. The mandibular structure 6 is connected to a tongue structure 5 via a magnetic snap-fit ​​structure 11. The magnetic snap-fit ​​structure 11 includes a magnetic female snap mounted on the upper surface of the mandibular structure 6 and a magnetic male snap mounted on the lower surface of the tongue structure 5 that cooperates with the magnetic female snap. Precise alignment is not required during installation; the magnetic snap-fit ​​will automatically adhere and align. Disassembly is achieved by simply lifting the tongue vertically and overcoming the magnetic force, facilitating flexible disassembly.

[0017] The front end of the tooth structure 3 is fitted with a lip structure 2, which is integrally formed with a cheek structure 1. The cheek structure 1 is connected to the outer wall of the upper and lower jaw structures via a flexible strap 8. Buckles 7 are symmetrically installed on the outer wall of the upper and lower jaw structures and on the inner wall of the cheek structure 1. The flexible strap 8 has eyelets 801 at both ends that match the buckles 7. The flexible strap 8 can be made of rubber. When the upper and lower jaw structures open and close, it pulls on the flexible strap 8, causing the flexible cheek structure 1 to open and close, simulating the process of a human opening their mouth. When the mouth is open, the lips and cheeks can be slightly stretched, bringing them closer to the labial side of the teeth.

[0018] The upper jaw structure and the lower jaw structure 6 are connected together by an upper and lower opening and closing mechanism 9, which is located on the side away from the lip structure 2 and can simulate the opening and closing action of the oral cavity.

[0019] The opening and closing mechanism 9 includes a vertically distributed mounting base 901. A second sector gear 904 and a first sector gear 903 are symmetrically mounted vertically on one side of the mounting base 901, and their teeth mesh together. A connecting rod 905 is mounted on the outer arc surface of each of the sector gears 904 and 903. The end of the connecting rod 905 is hinged to an opening and closing component 906. The end of the opening and closing component 906 away from the connecting rod 905 has a threaded hole 908, which is used to fix it to the upper and lower jaws by bolts or screws. A second connecting rod 907 is hinged to the center of the opening and closing component 906, and the other end of the second connecting rod 907 is hinged to the mounting base 901. The second sector gear 904 is rotatably mounted on the mounting base 901 via the second rotating shaft. The first sector gear 903 is keyed to the first rotating shaft, and the other end of the first rotating shaft passes through the mounting base 901 and is connected to the drive assembly.

[0020] Specifically, by driving the drive component to rotate forward and backward, the sector gear 903 rotates forward and backward, and the sector gear 904 meshing with it also rotates forward and backward, realizing the approach and distance movements between the connecting rods 905 on the sector gears. During the movement of the connecting rod 905, due to the limiting effect of the connecting rod 907, the end of the hinged opening and closing part 906 of it can open and close, thereby driving the upper and lower jaws to open and close. The opening and closing angle is controlled according to the rotation angle of the sector gears and the arrangement of the teeth on the sector gears.

[0021] The drive assembly includes a forward and reverse motor 902, which is a forward and reverse motor.

[0022] The lower end of the mounting base 901 is equipped with a support base 10 (which can be connected by bolts), which can be used to support the opening and closing mechanism 9 on a daily basis, thereby realizing the support operation for the three-dimensional intraoral model of the entire dynamic tooth and lip space demonstration.

[0023] The cheek structure 1, lip structure 2, and tongue structure 5 are made of flexible materials. The lip structure 2 can be flipped up, facilitating detailed examination of structures such as the gums during the education process and visually demonstrating blind spots in brushing. Furthermore, the tooth structure 3 includes irregularly arranged dentition, including protruding canines, crowded lower anterior teeth, and some teeth with frosted white patches to simulate demineralization. The gum structure 4 is made of flexible material, with some areas that can be flipped up, and features simulated redness and swelling to represent gingivitis or gingival recession. This allows for clear observation during the education process of plaque buildup at the gum-tooth junction (gingival margin), redness and swelling (gingivitis) or frosted white patches (demineralization) due to inadequate cleaning, and cleaning difficulties caused by malocclusion or orthodontic bracket interference.

[0024] The cheek structure 1 is made of a flexible transparent material, such as silicone, which allows the internal teeth and gum structure to be seen. The cheek structure 1 made of flexible transparent material has a certain stretch and elasticity, and simulates facial muscle tension when the mouth is open, further reducing the space that the toothbrush can enter.

[0025] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
