DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1-Figure 3 The utility model provides a palatal bead joint function regulator, including a tongue arch 1, a palatal arch 2, and a buccal screen 3. The tongue arch 1 is located at the inner side of the maxillary anterior teeth, and the two buccal screens 3 are located at the outer side of the upper and lower posterior teeth and are connected through the palatal arch 2. The utility model includes a palatal bead assembly 4, a tongue lifter 5, and a crown-linked oblique guide 6. The palatal bead assembly 4 is arranged on the palatal arch 2 and fits the top of the tongue. The tongue lifter 5 is arranged on the maxilla. A fixing steel wire 7 is arranged inside the tongue lifter 5. Both ends of the fixing steel wire 7 extend to the outside of the tongue lifter 5 and are connected to the two buccal screens 3. The crown-linked oblique guide 6 wraps the maxillary anterior teeth, and the crown-linked oblique guide 6 is arranged as an inclined surface toward the posterior tooth surface.

[0024] The tongue lifter 5 is U-shaped, with a through groove 51 extending from the bottom to the top, and a tongue groove 52 formed on one side of the tongue lifter 5 facing the upper jaw.

[0025] Reference Figure 1 , 2 The palatal bead component 4 and the tongue lifter 5 are both made of resin material. The selection of this material not only ensures the biocompatibility of the product, but also greatly improves its durability and comfort.

[0026] Reference Figure 4 A truncation opening is provided in the middle of the palatal arch 2, and the palatal bead assembly 4 is assembled and connected at the truncation opening of the palatal arch 2, so that the palatal bead assembly 4 has the characteristics of being installable and disassembled, and is convenient for disassembly and cleaning during use. After disassembly, it is more convenient for the patient to eat, and the use of the device is more flexible.

[0027] Reference Figure 5The palatal bead assembly 4 includes a main bead 41, which has spiral grooves at both ends, and end mounters 42 are movably connected in the spiral grooves at both ends. The outer ends of the two end mounters 42 are combined and connected with the cutoff ends of the palatal arch 2. The connection relationship between the two end mounters 42 and the main bead 41 ensures that the palatal bead assembly 4 can be rotated after installation, so that the patient can exercise the tongue muscles.

[0028] Reference Figure 5 The side wall of the end mounter 42 is provided with an annular groove, the inner wall of which is glued with a bearing 43, and the side wall of the bearing 43 is glued with the inner wall of the rotation groove of the end mounter 42. This arrangement can prevent the end mounter 42 from falling off from the rotation groove of the main bead 41 on the one hand, and reduce the rotational resistance of the end mounter 42 in the rotation groove of the main bead 41 on the other hand.

[0029] Reference Figure 6 The end mounter 42 includes an outer rotating shell 421, and a rotating cavity and a polygonal cavity that are interconnected are arranged inside the outer rotating shell 421. A fixed sleeve 422 is movably sleeved in the rotating cavity. A column groove and a threaded groove are arranged inside the fixed sleeve 422. A plug column 423 is slidably sleeved in the column groove, and a threaded column 424 is threadedly sleeved in the threaded groove. One end of the threaded column 424 is connected to the plug column 423, and the other end extends to the outside of the fixed sleeve 422 and is connected to a polygonal sliding column 425. The polygonal sliding column 425 is slidably sleeved in the polygonal cavity of the outer rotating shell 421, and a columnar embedding groove that matches the size of the plug column 423 is opened at the cutoff end of the palatal arch 2 22. When the end mounter 42 is combined with the cutoff end of the palatal arch 2, the cylindrical embedding groove 22 at the cutoff end of the palatal arch 2 is aligned with the column groove of the fixed sleeve 422. By rotating the outer rotating shell 421, the polygonal sliding column 425 and the shape characteristics of the polygonal cavity of the outer rotating shell 421 can make the polygonal sliding column 425 follow the rotation. At this time, the threaded column 424 is driven to rotate by the polygonal sliding column 425, so that the threaded column 424 and the fixed sleeve 422 are threadedly matched to produce lateral movement, thereby driving the plug 423 to move out of the column groove and embed into the cylindrical embedding groove 22 of the palatal arch 2, thereby completing the combination of the end mounter 42 and the palatal arch 2.

[0030] Reference Figure 6 A multi-deformation block 21 is also provided at the cutoff end of the palatal arch 2, and a polygonal inlay is provided on the end face of the outer rotating shell 421 facing the multi-deformation block 21. When the outer rotating shell 421 is rotated, the fixed sleeve 422 will be driven to rotate with it under the influence of friction, which makes it impossible for the threaded column 424 to move laterally. By providing the multi-deformation block 21 in cooperation with the polygonal inlay, the rotation of the fixed sleeve 422 can be restricted by the multi-deformation block 21, thereby avoiding the situation where the fixed sleeve 422 follows the rotation of the outer rotating shell 421.

[0031] The working principle of the utility model is as follows: through the positional relationship between the palatal bead assembly 4 and the human tongue, when the tongue moves, the palatal bead assembly 4 is driven to rotate to enhance the fun, thereby inducing the tongue to move frequently, thereby achieving the effect of exercising the tongue muscles. Since the palatal bead assembly 4 is located at the top of the tongue, it can assist the tongue in exercising the tongue rolling, thereby achieving the effect of assisting in correcting the low position of the tongue;

[0032] On this basis, a tongue lifter 5 is also provided. When the patient sticks out the tongue, the tip of the tongue can be inserted into the tongue groove 52 through the groove 51 of the tongue lifter 5. The tongue can be forced to be lifted up by the installation position of the tongue lifter 5, so as to achieve the forced adjustment of the tongue to a low position. Since the tip of the tongue is in the tongue groove 52, the tongue lifter 5 forms a barrier between the tip of the tongue and the front teeth, which can suppress the bad habit of sticking out the tongue on the one hand, and avoid the tooth protrusion caused by sticking out the tongue on the other hand.

[0033] In addition, the tongue lifter 5 can assist the traditional orthodontic appliance in correcting the "overbite" symptom. When the upper and lower jaws are closed, the mandibular front teeth can contact the inclined surface of the crown bevel guide 6. At this time, under the influence of the slope, the maxillary front teeth can be guided to move outward and the mandibular can be moved inward, thereby achieving the effect of auxiliary correction.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. The utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model.
