[0037] Teeth 200. Detailed Implementation

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] like Figures 1 to 3 As shown, the oral cavity track 100 of this embodiment includes an occlusal portion 1. The occlusal portion 1 is provided with an inner cavity 17, an intermediate cavity 16, an outer cavity 15, a first groove 14, and a second groove 18. The inner cavity 17, the outer cavity 15, the first groove 14, and the second groove 18 are all located on the periphery of the intermediate cavity 16. The inner cavity 17 and the outer cavity 15 are arranged opposite to each other, and the first groove 14 and the second groove 18 are arranged opposite to each other.

[0040] Specifically, the first groove 14 and the second groove 18 can be arranged opposite each other in the vertical direction, the intermediate cavity 16 can be located between the first groove 14 and the second groove 18, and the outer cavity 15 and the inner cavity 17 can be arranged opposite each other in the inward and outward direction (left-right or front-back direction). The intermediate cavity 16 can be located between the outer cavity 15 and the inner cavity 17. The inner cavity 17, the first groove 14, the outer cavity 15, and the second groove 18 can be sequentially connected in the circumferential direction of the intermediate cavity 16, thereby forming a closed-loop enclosure structure around the intermediate cavity 16.

[0041] The overall shape of the occlusal portion 1 can conform to the arrangement of the teeth 200 in the human oral cavity. For example, the occlusal portion 1 can be generally L-shaped, so that the occlusal portion 1 can be fixed between the upper and lower teeth 200 of the human body, making the shape of the occlusal portion 1 conform to half of the teeth 200 of the human body. When the other half of the teeth 200 needs care, the occlusal portion 1 can be flipped up and down and occluded between the upper and lower teeth 200 of the other half. At this time, in order to enhance the adaptability to the teeth 200 on different sides of the face, the first groove 14 and the second groove 18 can be arranged in a mirror-symmetrical manner in the vertical direction.

[0042] It is understood that in some other embodiments, the occlusal portion 1 may also be U-shaped or the like, so that it can occlude with all the teeth 200 in the oral cavity.

[0043] It should be noted that the inner cavity 17, the intermediate cavity 16, the outer cavity 15, the first groove 14, and the second groove 18 all extend along the extension direction of the occlusal part 1, thereby meeting the usage requirements of matching multiple teeth 200 arranged in the oral cavity.

[0044] The inner cavity 17, the intermediate cavity 16, and the outer cavity 15 are all connected to the first groove 14 and the second groove 18. For example, the top side of the inner cavity 17 can be connected to the first groove 14 through a through hole, and the bottom side of the inner cavity 17 can also be connected to the second groove 18 through a through hole. Similarly, the top sides of the intermediate cavity 16 and the outer cavity 15 can be connected to the first groove 14 through a through hole, and the bottom sides of the intermediate cavity 16 and the outer cavity 15 can also be connected to the second groove 18 through a through hole.

[0045] During use, such as Figure 4 and Figure 5 As shown, the oral track 100 can be fixed in place between the upper and lower teeth 200 of a human body. The upper teeth 200 can fit into the first groove 14, and the lower teeth 200 can fit into the second groove 18. After the bite is fixed, oral instruments such as a miniature scanning camera and a water flosser can be inserted into the inner cavity 17, the intermediate cavity 16, and the outer cavity 15. Taking the intermediate cavity 16 as an example, the oral instruments can be inserted into the intermediate cavity 16 and can move back and forth along the extension direction of the intermediate cavity 16. Through the through-hole, the oral instruments can be inserted into the first groove 14 and the second groove 18, thereby enabling the care (cleaning, filling, fluoride application, etc.) of the tooth surfaces of the upper and lower teeth 200.

[0046] Understandably, when the oral appliance is fitted within the inner cavity 17, it can provide care for the inner surfaces of both the upper and lower teeth 200. When the oral appliance is fitted within the outer cavity 15, it can provide care for the outer surfaces of both the upper and lower teeth 200.

[0047] The oral track 100 of this invention simplifies oral care operations, improves the situation of irritation of the gums or cheeks caused by improper operation in related technologies, and enables the operation of oral instruments in a space-restricted manner. That is, the oral instruments can only move back and forth within the inner cavity 17, the middle cavity 16 and the outer cavity 15. Compared with the situation of free space movement in the prior art, the care process is more targeted and the goal is clear, ensuring the accuracy of operation, reducing discomfort, and enhancing child-friendliness.

[0048] In some embodiments, the engagement portion 1 includes a housing 11, a first partition portion 12 and a second partition portion 13. One side of the housing 11 is recessed inward to define a first groove 14, and the other side of the housing 11 is recessed inward to define a second groove 18. The first partition portion 12 and the second partition portion 13 are both disposed within the housing 11 and divide the internal space of the housing 11 into an inner cavity 17, an intermediate cavity 16 and an outer cavity 15, and the intermediate cavity 16 is located between the first partition portion 12 and the second partition portion 13.

[0049] For example, the material of the biting part 1 can be silicone, etc., and the shell 11, the first partition 12, and the second partition 13 can be integrally molded. The shell 11 can be generally tubular, and the upper side of the shell 11 can be recessed downwards to form a first groove 14, and the lower side of the shell 11 can be recessed upwards to form a second groove 18. Figure 2 As shown, the first partition 12 and the second partition 13 can be disposed inside the housing 11 and can be arranged in parallel at intervals in the inward and outward directions, wherein the first partition 12 can be located outside the second partition 13.

[0050] The outer cavity 15 can be located outside the first partition 12, the intermediate cavity 16 can be located between the first partition 12 and the second partition 13, and the inner cavity 17 can be located inside the second partition 13. Thus, the first partition 12 and the second partition 13 can separate the space inside the shell 11, thereby simplifying the overall structure and achieving the separation of the outer cavity 15, the intermediate cavity 16 and the inner cavity 17.

[0051] On the other hand, the first partition 12 and the second partition 13 can play a supporting role in use, so that the occlusal part 1 can withstand the biting force of the human body without collapsing, which meets the needs of assembling and moving oral appliances, and also plays a role in protecting oral appliances.

[0052] In some embodiments, the first groove 14 has a first sidewall 141 and a second sidewall 142 arranged opposite to each other. The first sidewall 141 and the second sidewall 142 are both inclined and in opposite directions. The distance between the first sidewall 141 and the second sidewall 142 gradually decreases along the groove depth direction of the first groove 14.

[0053] For example, such as Figure 2 As shown, the two oppositely arranged side walls of the first groove 14 form a first side wall 141 and a second side wall 142, respectively. The first side wall 141 can be the outer wall of the first groove 14, and the second side wall 142 can be the inner wall of the first groove 14. The first side wall 141 can be arranged inclined from the upper outside to the lower inside, and the second side wall 142 can be arranged inclined from the upper inside to the lower outside. This makes the cross-section of the first groove 14 generally trapezoidal, meaning the width of the first groove 14 gradually decreases from top to bottom.

[0054] This design makes the opening of the first groove 14 wider, which facilitates the insertion of the teeth 200 into the first groove 14. The inclined arrangement of the first sidewall 141 and the second sidewall 142 can also play a certain guiding role, which facilitates the centering of the teeth 200 towards the middle position of the first groove 14. This can ensure the accuracy of the bite assembly and improve the adaptability to different types of teeth 200 in different people.

[0055] On the other hand, the first sidewall 141 and the second sidewall 142 have projection components in both the horizontal and vertical directions. The projection component in the horizontal direction facilitates the vertical connection between the first groove 14 and the inner cavity 17, as well as the vertical connection between the first groove 14 and the outer cavity 15. The projection component in the vertical direction can be opposite to the inner or outer surface of the tooth 200, thereby facilitating the care of the inner and outer surfaces of the tooth 200.

[0056] In addition, the inclined first sidewall 141 and second sidewall 142 can also guide the transmission of biting force. That is, the biting force can be transmitted to the first partition 12 and the second partition 13 through the first sidewall 141 and the second sidewall 142 respectively, thereby reducing the squeezing effect on the inner cavity 17 and the outer cavity 15, reducing the deformation of the inner cavity 17 and the outer cavity 15, and facilitating the movement of oral appliances in the outer cavity 15 and the inner cavity 17.

[0057] In some embodiments, the first groove 14 has a first bottom wall 143 connected between the first side wall 141 and the second side wall 142. The first bottom wall 143, the first side wall 141, and the second side wall 142 are each provided with a plurality of first holes 144 arranged at intervals along the extension direction of the occlusal portion 1. The first holes 144 are used to allow oral appliances to be inserted into the first groove 14.

[0058] For example, such as Figure 2As shown, the first bottom wall 143 is the bottom wall of the first groove 14. The first bottom wall 143, the first side wall 141, and the second side wall 142 can all be composed of multiple first connecting rods arranged at intervals along the extension direction of the occlusal part 1. A first hole 144 can be formed between any two adjacent first connecting rods. During use, oral instruments in the inner cavity 17, the intermediate cavity 16, and the outer cavity 15 can be inserted into the first groove 14 through the corresponding first hole 144, thereby enabling the care of the teeth 200 in the first groove 14.

[0059] The arrangement of the first link allows the first hole 144 to extend in both the inward and outward directions, enabling the dental instrument to care for the tooth 200 by swinging in and outward during use, thus improving the convenience and flexibility of operation. On the other hand, the first link also has a good elastic deformation effect, which can enlarge the diameter of the first hole 144 through deformation, thereby further facilitating the dental instrument to pass through the first hole 144 and care for the tooth 200.

[0060] It is understood that in some other embodiments, the first bottom wall 143, the first side wall 141, and the second side wall 142 may also have only one first hole 144, which can be an elongated hole and can be arranged to extend along the extension direction of the engagement portion 1.

[0061] In some embodiments, the second groove 18 has a third sidewall 181 and a fourth sidewall 182 arranged opposite to each other. The third sidewall 181 and the fourth sidewall 182 are both inclined and in opposite directions. The distance between the third sidewall 181 and the fourth sidewall 182 gradually decreases along the groove depth direction of the second groove 18.

[0062] For example, such as Figure 3 As shown, the two oppositely arranged side walls of the second groove 18 form a third side wall 181 and a fourth side wall 182, respectively. The third side wall 181 can be the outer wall of the second groove 18, and the fourth side wall 182 can be the inner wall of the second groove 18. The third side wall 181 can be arranged inclined from the bottom outside to the top inside, and the fourth side wall 182 can be arranged inclined from the bottom inside to the top outside. This makes the cross-section of the second groove 18 generally trapezoidal, meaning the width of the second groove 18 gradually decreases from bottom to top.

[0063] This design allows for a wider opening in the second slot 18, facilitating the insertion of the lower teeth 200 into the slot. The inclined arrangement of the third sidewall 181 and the fourth sidewall 182 also provides a guiding effect, making it easier to center the teeth 200 towards the middle of the second slot 18. This ensures accurate occlusal fitting and improves adaptability to different types of teeth 200 in different individuals.

[0064] On the other hand, the third sidewall 181 and the fourth sidewall 182 have projection components in both the horizontal and vertical directions. The horizontal projection component facilitates the vertical connection between the second groove 18 and the inner cavity 17, as well as the vertical connection between the second groove 18 and the outer cavity 15. The vertical projection component can be aligned with the inner or outer surface of the tooth 200, thus facilitating the care of the inner and outer surfaces of the tooth 200.

[0065] In addition, the inclined third sidewall 181 and fourth sidewall 182 can also guide the transmission of biting force. That is, the biting force can be transmitted to the first partition 12 and the second partition 13 through the third sidewall 181 and the fourth sidewall 182 respectively, thereby reducing the squeezing effect on the inner cavity 17 and the outer cavity 15, reducing the deformation of the inner cavity 17 and the outer cavity 15, and facilitating the movement of oral appliances in the outer cavity 15 and the inner cavity 17.

[0066] In some embodiments, the second groove 18 has a second bottom wall 183 connected between the third side wall 181 and the fourth side wall 182. The second bottom wall 183, the third side wall 181, and the fourth side wall 182 are each provided with a plurality of second holes 184 arranged at intervals along the extension direction of the occlusal portion 1. The second holes 184 are used to allow oral appliances to be inserted into the second groove 18.

[0067] For example, such as Figure 3 As shown, the second bottom wall 183 is the bottom wall of the second groove 18. The second bottom wall 183, the third side wall 181, and the fourth side wall 182 can all be composed of multiple second connecting rods arranged at intervals along the extension direction of the occlusal part 1. A second hole 184 can be formed between any two adjacent second connecting rods. During use, oral instruments in the inner cavity 17, the intermediate cavity 16, and the outer cavity 15 can be inserted into the second groove 18 through the corresponding second holes 184, thereby enabling the care of the teeth 200 in the second groove 18.

[0068] The arrangement of the second link allows the second hole 184 to extend in both the inward and outward directions, enabling dental instruments to care for the teeth 200 by swinging in and outward during use, thus improving the convenience and flexibility of operation. On the other hand, the second link also has a good elastic deformation effect, which can enlarge the diameter of the second hole 184 through deformation, thereby further facilitating the passage of dental instruments through the second hole 184 and the care of the teeth 200.

[0069] It is understood that in some other embodiments, the second bottom wall 183, the third side wall 181, and the fourth side wall 182 may also have only one second hole 184, which can be an elongated hole and can be arranged to extend along the extension direction of the engagement portion 1.

[0070] In some embodiments, the housing 11 includes an inner sidewall 112 and an outer sidewall 111 arranged opposite to each other. The inner cavity 17, the intermediate cavity 16, the outer cavity 15, the first groove 14, and the second groove 18 are all located between the inner sidewall 112 and the outer sidewall 111. The outer cavity 15 is located between the first partition 12 and the outer sidewall 111, and the inner cavity 17 is located between the second partition 13 and the inner sidewall 112.

[0071] For example, such as Figure 2 and Figure 3 As shown, both the inner wall 112 and the outer wall 111 can be generally plate-like structures, and both the inner wall 112 and the outer wall 111 can extend along the extension direction of the occlusal part 1. The inner wall 112 is located inside the outer wall 111. In use, the inner wall 112 is used to face the inside of the oral cavity, while the outer wall 111 is used to face the outside of the oral cavity.

[0072] The inner wall 112 and the outer wall 111 provide a protective effect. The inner wall 112 can keep the oral instrument inside the inner cavity 17, thereby preventing the oral instrument from protruding from the inner cavity 17 and easily injuring the tongue. The outer wall 111 can keep the oral instrument inside the outer cavity 15, thereby preventing the oral instrument from protruding from the outer cavity 15 and easily injuring the cheek, thus improving the safety of use.

[0073] In addition, the inner wall 112 and the outer wall 111 have relatively high structural strength, so they can play a supporting role together with the first partition 12 and the second partition 13, reducing the deformation of the occlusal part 1 during occlusion and ensuring the smooth movement of the oral appliance in the inner cavity 17, the intermediate cavity 16 and the outer cavity 15.

[0074] In some embodiments, such as Figure 5 As shown, the cross-sections of the inner wall 112, the outer wall 111, the first partition 12, and the second partition 13 are all arc-shaped, specifically circular arc-shaped. The outer wall 111, the first partition 12, and the second partition 13 all extend outwards from the oral cavity track 100. Figure 5 The left side of the middle protrudes, and the inner wall 112 extends towards the inner side of the oral cavity track 100. Figure 5 (Protruding on the right side of the middle)

[0075] During occlusion, the outer wall 111, the first partition 12, and the second partition 13 all bulge outwards from the outside of the oral appliance, while the inner wall 112 bulges inwards from the inside. This causes the overall deformation of the oral appliance during occlusion to tend outwards, conforming to ergonomic design and reducing pressure on the oral cavity, thereby improving comfort during occlusion and further reducing discomfort.

[0076] Secondly, the arc design facilitates smooth connections, thereby eliminating stress concentration, and also enhances structural strength and elasticity, thus fully meeting the needs of use.

[0077] In addition, the arc-shaped design can also form a guide groove-like structure on the concave surfaces of the inner wall 112, the outer wall 111, the first partition 12, and the second partition 13, thereby improving the guidance of the movement of the oral instrument and enhancing the restraint effect.

[0078] In some embodiments, such as Figure 5 As shown, the cross-sectional (vertical section) profile of the outer sidewall 111 is located on the first ellipse 4, the cross-sectional (vertical section) profile of the first partition 12 is located on the second ellipse 5, and the cross-sectional (vertical section) profiles of the second partition 13 and the inner sidewall 112 are located on the third ellipse 6. The centers of the first ellipse 4, the second ellipse 5, and the third ellipse 6 are all located in the same plane. For example, the centers of the first ellipse 4, the second ellipse 5, and the third ellipse 6 can be located in the same horizontal plane.

[0079] This makes the overall structure of the occlusal part 1 symmetrical from top to bottom. When the occlusal part is fixed, it can be ensured that the outer side wall 111, the first partition part 12, the second partition part 13, and the inner side wall 112 have approximately the same amount of deformation on both the top and bottom sides, thus ensuring the consistency between the top and bottom.

[0080] In some embodiments, the extension direction of the major axis of the second ellipse 5 is consistent with the spacing direction of the first partition 12 and the second partition 13, and the extension directions of the major axis of the first ellipse 4 and the third ellipse 6 are both orthogonal to the extension direction of the major axis of the second ellipse 5.

[0081] For example, such as Figure 5As shown, the major axis of the second ellipse 5 can generally extend in the left-right direction, while the major axes of the first ellipse 4 and the third ellipse 6 can both extend in the up-down direction. This design facilitates the definition of the first groove 14 and the second groove 18, and also allows the minor axes of the first ellipse 4 and the second ellipse 5 to be horizontal, thereby reducing the overall lateral dimension of the oral cavity guide, facilitating its fit within the oral cavity, and further improving occlusal comfort.

[0082] Furthermore, since the minor axis of the second ellipse 5 extends along the vertical direction, this design gives the second ellipse 5 strong structural strength in the vertical direction, thus fully meeting the needs of bearing the biting action of the teeth 200. At the same time, it can also reduce the distance between the upper and lower teeth 200 during biting, further improving biting comfort.

[0083] Optionally, such as Figure 5 As shown, the major axis of the first ellipse 4 can be 26 mm, and the minor axis can be 10 mm. The distance between the first partition 12 and the second partition 13 in the left-right direction can be 15 mm. The major axis of the third ellipse 6 can be 20 mm, and the minor axis can be 13 mm.

[0084] In some embodiments, the oral track 100 includes a guide portion 2 connected to the occlusal portion 1. At least a portion of the guide portion 2 is used to extend to the outer side of the human oral cavity, and the guide portion 2 is provided with a guide hole 211 for guiding oral appliances into the inner cavity 17, the intermediate cavity 16 or the outer cavity 15.

[0085] For example, such as Figure 1 As shown, the guide part 2 can be integrally formed with the engagement part 1. The guide part 2 can be generally a tubular structure, and the internal space of the guide part 2 forms a guide hole 211. Figure 2 As shown, the guide hole 211 can be directly aligned with the inlet of the inner cavity 17, the inlet of the intermediate cavity 16, and the inlet of the outer cavity 15. The width dimension L1 of the guide hole 211 in the inner and outer directions can match the overall width dimension L2 of the inner cavity 17, the intermediate cavity 16, and the outer cavity 15 in the inner and outer directions. For example, the width dimension L1 can be roughly consistent with the width dimension L2.

[0086] When using, such as Figure 4 As shown, the biting part 1 can be fixed in the oral cavity, the guiding part 2 can extend from the mouth and be located outside the human body, and the oral appliance can be inserted through the guiding hole 211. Then the oral appliance can be inserted into the outer cavity 15, the middle cavity 16, and the inner cavity 17 respectively, which facilitates the assembly of the oral appliance. At the same time, it also plays a protective role, that is, it avoids the oral appliance from easily touching the mouth during use and causing damage.

[0087] In some embodiments, the guide portion 2 includes a tube body 21, a first connecting plate 22 and a second connecting plate 23. The first connecting plate 22 and the second connecting plate 23 are arranged opposite each other in a direction orthogonal to the interval between the first groove 14 and the second groove 18, and the first connecting plate 22 and the second connecting plate 23 are smoothly connected between the tube body 21 and the engagement portion 1. The guide hole 211 is provided in the tube body 21.

[0088] For example, such as Figure 1 and Figure 3 As shown, both the first connecting plate 22 and the second connecting plate 23 can be arc-shaped long plates, and the tube body 21 can be roughly square tube-shaped. One end of the first connecting plate 22 can be connected to the outside (left side) of the tube body 21, and the other end of the first connecting plate 22 can be smoothly connected to the outer wall 111 of the shell 11. One end of the second connecting plate 23 can be connected to the inside (right side) of the tube body 21, and the other end of the second connecting plate 23 can be smoothly connected to the inner wall 112 of the shell 11.

[0089] The arrangement of the first connecting plate 22 and the second connecting plate 23 can, on the one hand, enhance the overall length of the guide part 2, thereby increasing the extension of the guide part 2 to the outer side of the oral cavity. On the other hand, the first connecting plate 22 and the second connecting plate 23 have good elastic deformation capabilities, which allows the orientation and position of the tube body 21 to be adaptively adjusted during use, further improving the comfort of use.

[0090] In some embodiments, the oral track 100 includes a limiting part 3, which blocks the outlet ends of the inner cavity 17, the intermediate cavity 16, and the outer cavity 15 to prevent oral appliances from extending out of the biting part 1 from the inner cavity 17, the intermediate cavity 16, and the outer cavity 15.

[0091] For example, such as Figure 1 and Figure 3 As shown, the limiting part 3 can be integrally formed at the tail end of the occlusal part 1. The limiting part 3 can be a plate-like structure. The limiting part 3 can block the outlet ends of the inner cavity 17, the intermediate cavity 16, and the outer cavity 15, thereby preventing the oral instrument from protruding from the outlet end of the corresponding cavity. This achieves the limiting effect on the oral instrument and also prevents the oral instrument that extends to the outside of the occlusal part 1 from easily injuring the human body, further improving safety and protection.
