[0003] Currently, commonly used methods for oral plaque detection mainly include two approaches: plaque chewing tablets and plaque detection solution application. Using plaque chewing tablets requires patients to chew thoroughly for 1 to 3 minutes to ensure effective contact between the plaque detection components and the tooth surface. This method is difficult to achieve the desired chewing effect for children or people with weak chewing abilities, resulting in the plaque detection components not being evenly distributed on the tooth surface, thus affecting the accuracy of the test results.

[0004] In addition, although the plaque detection solution application method can ensure the uniform application of the test solution, the operation usually needs to be performed by a professional dentist in a dental clinic. Patients cannot perform it independently. This reliance on external assistance not only limits the convenience of its application but also reduces its popularity, making it difficult to meet the growing demand for oral self-care.

[0005] Therefore, existing technologies still need improvement. Utility Model Content

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses an oral tray for plaque detection. Please refer to [link to relevant documentation]. Figure 1 The inner shell 100 is recessed inward to form a first groove 110; the first groove 110 is used to fit the teeth; the first groove 110 is provided with a limiting hole 111; the limiting hole 111 is used to place plaque detection particles; the plaque detection particles at least partially protrude outside the limiting hole 111.

[0028] In use, the size of the limiting hole 111 is smaller than the plaque detection particle. When the plaque detection particle is placed in the limiting hole 111, the limiting hole 111 can lock the plaque detection particle in place, and the plaque detection particle protrudes outside the limiting hole 111. When the teeth bite the inner shell 100, the teeth contact and puncture the part of the plaque detection particle that protrudes outside the limiting hole 111, so that the plaque detection liquid flows out, allowing the plaque detection liquid to wet the teeth and make full contact with the teeth.

[0029] Specifically, in this embodiment, the inner shell 100 has different sizes, and the first groove 110 of different sizes has different depths to flexibly adapt to the size of the patient's teeth, so that the inner shell 100 can better fit the tooth surface and ensure that the plaque detection liquid can fully contact the tooth surface. As can be seen, this embodiment provides a limiting hole 111 in the inner shell 100 to place plaque detection particles. At the same time, the limiting hole 111 also plays a role in positioning the plaque detection particles. By biting the inner shell 100, the plaque detection process can be completed. The structure is simple, convenient to use, does not require professional operation, and does not require repeated chewing.

[0030] In another embodiment of this utility model, please refer to Figure 1 The limiting holes 111 are provided in multiple ways; the multiple limiting holes 111 are evenly arranged along the axial direction of the first groove 110. In actual use, the multiple limiting holes 111 are evenly arranged along the axial direction of the first groove 110, and each limiting hole 111 is filled with plaque detection particles, so that the plaque detection solution can stain the tooth surface more evenly. Specifically, the first groove 110 is provided with three limiting holes 111, one limiting hole 111 is provided at each end of the inner shell 100, and one limiting hole 111 is also provided in the middle. All three limiting holes 111 are filled with plaque detection particles; when the inner shell 100 is bitten, the three plaque detection particles break, and can quickly soak the molars and anterior molars in a short time to complete the plaque detection process.

[0031] In this embodiment, the first groove 110 is wavy. Setting the shape of the first groove 110 to be wavy makes the first groove 110 form a certain curve. When the inner shell 100 is engaged, the fluidity of the plaque detection liquid is increased, so that the plaque detection liquid can more evenly wet the tooth surface.

[0032] In another embodiment of this utility model, please refer to Figure 1 and Figure 2The oral cavity tray for plaque detection also includes an outer shell 200; the outer shell 200 is recessed inward to form a second groove, and the outer shell 200 is nested on the inner shell 100; there is a hollow space between the outer shell 200 and the inner shell 100 to form a first fluid channel 300; the first groove 110 is also provided with a second fluid channel 112; the first fluid channel 300 and the second fluid channel 112 are connected.

[0033] In use, the inner shell 100 is embedded in the outer shell 200, and a first fluid channel 300 is formed between the outer shell 200 and the inner shell 100. One end of the first fluid channel 300 is sealed, and the other end is provided with a through hole. The first groove 110 is provided with a second fluid channel 112 that communicates with the first fluid channel 300. Plaque detection liquid is poured into the first fluid channel 300 through the through hole. When the inner and outer shells 200 are engaged, the inner and outer shells 200 are squeezed against each other, causing the plaque detection liquid in the first fluid channel 300 to be sprayed out through the second fluid channel 112 and flow onto the tooth surface.

[0034] Specifically, the oral tray comes in different sizes, and each size has a different depth of the first groove 110 and the second groove. By setting the first fluid channel 300 and the second fluid channel 112, the plaque detection liquid can flow more quickly in the first groove 110 at different depths, so as to more comprehensively and quickly wet the tooth surface. It does not require multiple bites of the inner shell 100 and the outer shell 200, nor does it require the reliance on professionals. The plaque detection process can be completed independently. The oral tray has a simple structure and is easy to use.

[0035] In this embodiment, the limiting hole 111 is provided on the bottom wall of the first groove 110; the second fluid channel 112 is provided on the side wall of the first groove 110.

[0036] Please refer to the following for actual use. Figure 1 and Figure 2 The limiting hole 111 is located on the bottom wall of the first groove 110, and the plaque detection particles are located on the limiting hole 111. At the same time, the second fluid channel 112 is located on the side wall of the first groove 110. When the inner shell 100 and the outer shell 200 are engaged, the plaque detection particles break and wet the tooth surface from the bottom side of the tooth. The plaque detection liquid placed in the first fluid channel 300 is squeezed and flows out from the second fluid channel 112, wetting the tooth surface from the top side of the tooth. At this time, the plaque detection liquid wets the tooth surface in all directions to ensure that the plaque detection liquid wets all angles of the tooth surface.

[0037] In this embodiment, the second fluid channel 112 can be disposed on the upper sidewall or the lower sidewall of the first groove 110, or it can be disposed on both the upper sidewall and the lower sidewall of the first groove 110.

[0038] In this embodiment, the inner shell 100 and the outer shell 200 are made of soft materials, so both ends of the first fluid channel 300 can be sealed. The plaque detection solution is injected into the first fluid channel 300 through a needle hole and a syringe. The needle hole is very small, so when the inner shell 100 and the outer shell 200 are engaged, the plaque detection solution stored in the first fluid channel 300 can also be pressurized and flow out from the second fluid channel 112. In actual use, the inner shell 100 includes any one of a silicone shell, a rubber shell, a latex shell, and a disposable paper shell; and / or, the outer shell 200 includes any one of a silicone shell, a rubber shell, a latex shell, and a disposable paper shell.

[0039] In this embodiment, the outer shell 200 has a thickness of 0.5-1.5 mm; the inner shell 100 has a thickness of 1.0-2.0 mm.

[0040] In practical use, the outer shell 200 is thinner than the inner shell 100. Making the outer shell 200 thinner allows for better engagement with the inner shell 100, ensuring that plaque detection particles can be broken in a single bite. Simultaneously, it ensures that the plaque detection solution stored in the first fluid channel 300 receives sufficient pressure to flow out through the second fluid channel 112. Specifically, the outer shell 200 is 1 mm thick, and the inner shell 100 is 1.5 mm thick, ensuring that plaque detection solution can wet the tooth surface with a single bite, eliminating the need for multiple bites.

[0041] The oral cavity tray for plaque detection disclosed in this application can be either a disposable item or a reusable item. When the oral cavity tray is a disposable item, the plaque detection particles are pre-positioned in the limiting hole 111 during factory installation; simultaneously, the plaque detection liquid first flows into the first fluid channel 300, and then both ends of the first fluid channel 300 are sealed. The inner shell 100 and the outer shell 200 are integrally formed, and can be disassembled and engaged during use. When the oral cavity tray is a reusable item, after each use, the plaque detection particles are placed back into the limiting hole 111 for the next detection.

[0042] In this embodiment, the oral tray for plaque detection is provided with an upper tray and a lower tray. The upper tray can be used for the upper molars, and the lower tray can be used for the lower molars. The upper and lower trays are symmetrically arranged and used in the same way.

[0043] In another embodiment of this utility model, please refer to Figure 1 and Figure 2 The oral tray for plaque detection also includes a sealing cap 400; the sealing cap 400 is inserted at both ends of the first fluid channel 300 to seal the first fluid channel 300.

[0044] In use, a sealing cap 400 is inserted at both ends of the first fluid channel 300. The thickness of the sealing cap 400 is greater than the thickness of the inner shell 100 and the outer shell 200. When the sealing cap 400 covers the first fluid channel 300, the plaque detection solution stored in the first fluid channel 300 can be pressurized and flow out from the second fluid channel 112 when the inner shell 100 and the outer shell 200 are engaged. At the same time, the plaque detection solution can be added in time by opening and closing the sealing cap 400.

[0045] In this embodiment, please refer to Figure 2 and Figure 3 The sealing cap 400, inner shell 100, and outer shell 200 are integrally formed; the shape of the first groove 110 and the shape of the second groove are both "U" shaped to better adapt to the arrangement of human teeth and facilitate biting. A handle 500 is provided on the outer side wall of the outer shell 200 for easy removal and placement of the oral tray.

[0046] In summary, this application discloses an oral tray for plaque detection, comprising: an inner shell, the inner shell being concave inward to form a first groove; the first groove being for conforming to teeth; the first groove having a limiting hole; the limiting hole being for placing plaque detection particles; and the plaque detection particles at least partially protruding beyond the limiting hole.
