[0026] The present application is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the present application with reference to the description.

[0027] Embodiment 1

[0028] Figure 1 and Figure 2 The embodiment of the present application shown provides a 3D tongue-sticking prevention tongue grille, comprising a 3D printed connecting rod 1, a retaining member 2, and a tongue body limiting member 3;

[0029] The tongue stopper 3 is mounted on the connecting rod 1 to limit the tongue; the retainer 2 is mounted on the connecting rod 1 and connected to the teeth to fix the tongue stopper 3; wherein the connecting rod 1 may be a U-shaped rod, which is similar in shape to the gums and can fit on the surface of the inner gums, so that the tongue stopper 3 is closer to the inner wall of the oral cavity;

[0030] See also Figure 1 As a preferred embodiment of the present application, the tongue stopper 3 can be a plurality of tongue thorn rods 31 installed on the connecting rod 1, and the tongue thorn rods 31 are evenly arranged in the middle area of ​​the U-shaped rod and the covering width is not less than the width of the wearer's front teeth; the tongue thorn rods 31 are arranged to extend upward in contact with the surface of the gums and teeth, and the height of the free end of the tongue thorn rods 31 is equal to the height of the teeth, so as to ensure that the tongue thorn rods 31 can completely block the tongue tip from touching the front teeth when the wearer's tongue is extended; wherein, a gap is provided between the tongue stopper 3 and the teeth, and this technical method can prevent the tongue from passing through the tongue thorn rods 31 and touching the teeth, and the wearer's tongue tip can also be prevented from passing through the tongue thorn rods 31 by controlling the gap width between the tongue thorn rods 31; by adopting the above technical method, when the wearer unconsciously sticks out the tongue or stretches out the tongue to swallow, the tongue thorn rods 31 can form a barrier between the tongue and the front teeth, thereby achieving a correction effect; the tongue thorn rods 31 and the connecting rod 1 are compact in structure and both fit the inner side of the oral cavity, occupying less space inside the oral cavity, making the wearing experience more comfortable and natural;

[0031] See also Figure 2 As a preferred embodiment of the present application, the free end of the tongue thorn rod 31 is provided with an arc rod 32, and the arc rod 32 connects the free end of the tongue thorn rod 31 as a whole. When the wearer extends his tongue to touch the upper end of the tongue thorn rod 31, the contact part is the arc rod 32, which is more comfortable to touch; it can be understood that if Figure 3 As shown, the tongue limiter can also be designed as a wavy tongue bar 31. In this technical solution, the end of the tongue bar 3 adopts a rounded design, which can also make the wearer's tongue more comfortable when touching the tongue bar 31.

[0032] The retaining member 2 can be a brace printed by 3D printing according to the surface shape of the wearer's teeth. The brace is symmetrically mounted on the teeth. When the wearer's tongue touches the tongue limiter 3, the teeth can be subjected to symmetrical pulling force; the ends of the connecting rod 1 can be fixedly connected to the tongue side of the brace respectively, so as to stabilize the tongue limiter 3.

[0033] The connecting rod 1, retaining part 2 and tongue limiter 3 in this embodiment adopt 3D printing technology. The doctor only needs to perform a digital scan in the wearer's mouth to generate a three-dimensional model of the wearer's mouth, and design and produce it on this basis; the 3D printed anti-tongue-sticking tongue guard has the characteristics of high precision, high efficiency and high reliability, which can greatly reduce the production time and manual errors. At the same time, the connecting rod 1, retaining part 2 and tongue limiter 3 can be customized according to the wearer's oral structure, thereby improving the patient's comfort and treatment effect; the use of 3D anti-tongue-sticking tongue guard can also help doctors more accurately evaluate and plan treatment plans, and improve treatment effects and success rates.

[0034] Embodiment 2

[0035] See also Figure 4 The embodiment of the present application provides a 3D tongue-sticking-proof tongue guard, which differs from the first embodiment in that: in this embodiment, the tongue limiter 3 is evenly arranged along the connecting rod 1 and the two ends are respectively connected to the retaining member 2, wherein the tongue limiter 3 can be a structure in which the tongue thorn rod 31 and the arc rod 32 in the first embodiment cooperate, or it can be a baffle structure installed along the connecting rod 1, and a hollow through hole for saliva to pass through is provided on the baffle structure; in the above technical scheme, the tongue limiter 3 is laid along the connecting rod 1 to the retaining member 2, which can not only separate the front teeth and the tongue, but also separate the canines and molars on both sides of the front teeth from the tongue, which can effectively prevent patients with upper and lower jaw malocclusion and tongue hypertrophy from frequently biting the edge of the tongue while sleeping, thereby playing a corrective role.

[0036] Among them, the retaining component 2 is a molar brace installed on the molar. The molar brace adopts a ring structure with upper and lower openings and is close to the side of the molar. This technical method makes the retaining component 2 easy to disassemble and assemble. During installation, the molar brace only needs to be placed on the molar and pressed to fix it. The upper surface of the molar with the molar brace will not be covered, so that the occlusal surface will not be affected by the retaining component 2 when biting food, further improving the patient's wearing experience.

[0037] It is understandable that the molar braces can be customized according to the wearer's needs through 3D printing technology: molar braces that can be mounted on multiple molars. This technical method increases the contact area between the molar braces and the teeth, thereby increasing the stability of the installation of the retaining member 2, and can prevent the retaining member 2 from falling off when the wearer turns over in sleep or when the oral environment changes drastically.

[0038] Embodiment 3

[0039] Since the upper front teeth are located further outward in the oral cavity than the lower front teeth, when the mouth is in a closed state, the tongue stopper 3 located in the upper jaw is likely to contact the lower front teeth, affecting the wearer's experience. The embodiment of the present application provides a 3D tongue-sticking prevention tongue guard, please refer to Figure 5 and Figure 6 , the difference from the first embodiment and the second embodiment is that: the tongue stopper 3 is bent toward the inside of the oral cavity on the side away from the connecting rod, and a space for accommodating the lower front teeth is formed between the bent tongue stopper 3 and the upper front teeth. For patients who have worn other functional appliances on the lower jaw, the tongue-sticking-proof tongue fence can be installed on the upper jaw; it can be understood that the 3D-printed connecting rod 1 can also be used to ensure the fit between the connecting rod 1 and the upper jaw of the wearer, and the entire tongue fence can be fixed by installing the molar braces on the upper molars; the upper end of the tongue stopper 3 in this embodiment is designed to be bent toward the inside of the oral cavity, and the bending length is customized according to the positional relationship between the upper front teeth and the lower front teeth of the wearer. When the wearer's mouth is in a closed state, part of the tongue stopper 3 is still in a fit state with the upper front teeth, and the lower front teeth can be located in the space formed by the bent tongue stopper 3 and the upper front teeth, thereby solving the technical problem of the tongue stopper 3 conflicting with the lower front teeth.

[0040] Embodiment 4

[0041] The present application embodiment provides a 3D anti-tongue-sticking tongue grille. Figure 7 , the difference from Example 1, Example 2 and Example 3 is that: the connecting rod 1 is arranged along the edge of the dental row, and the tongue limiter 3 is connected to the upper and lower sides of the connecting rod 1 and is located on the inner side of the teeth; it can be understood that the structure of the tongue limiter 3 can be any one of Example 1, Example 2 or Example 3. By adopting this technical method, the anti-tongue-sticking tongue guard can simultaneously prevent the tongue from contacting the upper and lower teeth, thereby achieving the effect of preventing the teeth from opening the jaw.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
