[0002] An appliance is a device used for correcting tooth and jaw deformities. By applying appropriate forces, it adjusts the position, arrangement, and occlusion relationship of teeth, thereby improving the appearance and function of teeth. There are various types of appliances, including the Frankel Ⅲ appliance, also known as the FR-Ⅲ appliance, which is a functional appliance for correcting tooth and jaw development. It is mainly applicable to mild maxillary hypoplasia, with the mandible being basically normal or slightly protruded (i.e., underbite). The main purpose is to stimulate maxillary development and inhibit mandibular development.

[0003] During the process of stimulating maxillary development with the existing appliance, the condition of maxillary anterior tooth torsion is likely to occur, that is, the teeth are skewed and uneven, and the FR-Ⅲ appliance cannot achieve the effect of correcting maxillary anterior tooth torsion, resulting in the problem of functional deficiency. Summary of the Utility Model

[0004] To overcome the above-mentioned defects of the prior art, the utility model provides a tongue spring combined functional appliance to solve the problem that the traditional FR-Ⅲ appliance has a single function and cannot correct the condition of maxillary anterior tooth torsion during the correction process in the above-mentioned background art.

[0005] The utility model provides the following technical solution: A tongue spring combined functional appliance includes a tongue arch assembly, a connecting wire, and two lip stops. The two lip stops are fixed on the connecting wire. A plurality of tongue spring main parts are fixedly connected to the side wall of the tongue arch assembly. The plurality of tongue spring main parts are respectively in contact with a plurality of maxillary anterior teeth. The tongue spring main part is composed of an S-shaped elastic sheet, a cross bar, and a connecting rod. The cross bar is fixedly connected to one end of the S-shaped elastic sheet, and the length of the cross bar is adapted to the width of the corresponding maxillary anterior tooth. The connecting rod is fixedly connected to the other end of the S-shaped elastic sheet, and the connecting rod is fixedly connected to the side wall of the tongue arch assembly. The tongue arch assembly includes a main tongue arch and two side fixing tongue arches. The main tongue arch is used to abut against the maxillary anterior teeth, and both ends of the main tongue arch are respectively connected to the two side fixing tongue arches through two telescopic connecting pieces.

[0006] Further, the telescopic connecting piece includes an outer cylinder, a threaded column is threadedly sleeved in the inner cavity of the outer cylinder. One end of the threaded column is fixedly connected with a knob. The end face of the outer cylinder is fixedly connected to the side fixing tongue arch, and one side of the knob is fixedly connected to the main tongue arch.

[0007] Further, a sliding cylinder is movably sleeved on the side wall of the outer cylinder, and one end of the sliding cylinder is fixedly connected to the knob.

[0008] Furthermore, an outer convex ring is fixedly connected to one end of the outer cylinder side wall, an inner convex ring is arranged on the inner wall of the slide cylinder, the inner convex ring is slidably sleeved on the outer cylinder side wall, and the outer convex ring is slidably sleeved on the inner cavity of the slide cylinder.

[0009] Furthermore, the knob includes a main body button, one side of the main body button is fixedly connected to a fixing ring, the inner wall of the fixing ring is provided with an annular groove, an embedded ring is movably sleeved in the annular groove, the inner wall of the embedded ring is fixedly connected to a rotating disk, and one side of the rotating disk is connected to the tongue arch of the main body.

[0010] Furthermore, two arc rods of the connector are connected on the inner side of the two lip guards, the curvature of the arc rods is adapted to the curvature of the maxillary anterior teeth, and a plurality of support frames are fixedly connected to the side walls of the arc rods, and the plurality of support frames are respectively abutted against a plurality of maxillary anterior teeth, and the height of the support frames is adapted to the height of the maxillary anterior teeth.

[0011] Furthermore, the connector includes a shell, a slider is arranged inside the shell, an anti-detachment column is fixedly connected to the inner wall of the shell, the slider is slidably sleeved on the side wall of the anti-detachment column, the slider is transmission connected to the inner wall of the shell through a spring, and one end of the arc rod is connected to the slider.

[0012] Technical effects and advantages of the utility model:

[0013] The utility model adds a structure to prevent the maxillary anterior teeth from twisting on the basis of the original FR-Ⅲ orthodontic appliance. While the tongue arch component is used to abut against the maxillary teeth to stimulate their development, a plurality of tongue spring main parts are used to abut against the maxillary teeth separately, thereby limiting the twisting of the maxillary anterior teeth and achieving the effect of correcting the deflection of the maxillary anterior teeth, making the orthodontic appliance more functional.

[0014] The structure of the lingual arch assembly is improved. By setting two telescopic connecting pieces, the pressure of the lingual arch assembly against the maxilla can be adjusted to avoid improper installation of the appliance, which causes the lingual arch assembly and the tongue spring main part to exert too much or too little pressure on the maxillary anterior teeth, resulting in overcorrection or failure to achieve a good correction effect. By improving the structure of the lingual arch assembly, the error tolerance rate of the appliance installation can be effectively improved.

[0015] In addition, arc rods and support frames are provided, which can be used to abut the outer sides of the maxillary anterior teeth, thereby limiting the outward inclination of the maxillary anterior teeth during development (i.e., protruding teeth), thereby avoiding tooth growth deformities during the correction of the maxillary anterior teeth and further improving the functionality of the orthodontic device.

Detailed implementation manners

[0025] The following will describe in detail the detailed implementation manners of the present utility model with reference to the accompanying drawings.

[0026] Refer to Figures 1-3, the present utility model provides a tongue spring combined functional appliance, which includes a tongue arch assembly 1, a connecting wire 2, and two lip stops 3. The two lip stops 3 are fixed on the connecting wire 2. A plurality of tongue spring main parts 4 are fixedly connected to the side wall of the tongue arch assembly 1. The plurality of tongue spring main parts 4 are respectively in contact with a plurality of maxillary anterior teeth. The tongue spring main part 4 is composed of an S-shaped elastic piece 41, a cross bar 42, and a connecting rod 43. The cross bar 42 is fixedly connected to one end of the S-shaped elastic piece 41. The length of the cross bar 42 is adapted to the width of the corresponding maxillary anterior tooth. The connecting rod 43 is fixedly connected to the other end of the S-shaped elastic piece 41. The connecting rod 43 is fixedly connected to the side wall of the tongue arch assembly 1. The tongue arch assembly 1 includes a main body tongue arch 11 and two side fixing tongue arches 12. The main body tongue arch 11 is used to abut against the maxillary anterior teeth. Both ends of the main body tongue arch 11 are respectively connected to the two side fixing tongue arches 12 through two telescopic connectors 13.

[0027] Referring to Figure 4 , the telescopic connector 13 includes an outer cylinder 131. A threaded column 133 is threadedly sleeved in the inner cavity of the outer cylinder 131. One end of the threaded column 133 is fixedly connected to a knob 132. The end face of the outer cylinder 131 is fixedly connected to the side fixing tongue arch 12. One side of the knob 132 is fixedly connected to the main body tongue arch 11. During use, by rotating the knob 132 to drive the threaded column 133 to rotate, through the threaded cooperation relationship between the threaded column 133 and the outer cylinder 131, the telescopic effect of the telescopic connector 13 can be achieved.

[0028] Referring to Figure 4 , a sliding cylinder 134 is movably sleeved on the side wall of the outer cylinder 131. One end of the sliding cylinder 134 is fixedly connected to the knob 132. The threaded structure of the threaded column 133 may cause discomfort when contacting the oral epithelium. By setting the sliding cylinder 134, the threaded column 133 can be blocked to avoid discomfort caused by the contact between the threaded structure of the threaded column 133 and the oral epithelium.

[0029] Referring to Figure 5 , one end of the side wall of the outer cylinder 131 is fixedly connected to an outer convex ring 135. An inner convex ring 136 is arranged on the inner wall of the sliding cylinder 134. The inner convex ring 136 is slidably sleeved on the side wall of the outer cylinder 131. The outer convex ring 135 is slidably sleeved in the inner cavity of the sliding cylinder 134. When the telescopic connector 13 extends, the sliding cylinder 134 slides outward on the side wall of the outer cylinder 131. To prevent the sliding cylinder 134 from falling off the side wall of the outer cylinder 131, by setting the outer convex ring 135 and the inner convex ring 136, when the sliding cylinder 134 slides outward to a certain distance, the inner convex ring 136 contacts the outer convex ring 135, which can prevent the sliding cylinder 134 from falling off the side wall of the outer cylinder 131.

[0030] Referring to Figure 6, the knob 132 includes a main body knob 1321. A fixing ring 1322 is fixedly connected to one side of the main body knob 1321. An annular groove is formed in the inner wall of the fixing ring 1322. An embedded ring 1323 is movably sleeved in the annular groove. A rotating disk 1324 is fixedly connected to the inner wall of the embedded ring 1323. One side of the rotating disk 1324 is connected to the main body tongue arch 11. When the knob 132 rotates, it will cause torsion to the main body tongue arch 11. To prevent the main body tongue arch 11 from deforming or shifting, due to the connection relationship of the embedded ring 1323 in the annular groove of the fixing ring 1322, when the knob 132 rotates, the rotating disk 1324 connected to the main body tongue arch 11 does not rotate, thereby avoiding affecting the main body tongue arch 11.

[0031] Referring to Figure 7 , on the inner sides of two lip stops 3, two arc-shaped rods 5 are connected through a connector 7. The arc of the arc-shaped rod 5 is adapted to the arc of the maxillary anterior teeth. A plurality of support frames 6 are fixedly connected to the side wall of the arc-shaped rod 5. The plurality of support frames 6 are respectively abutted against a plurality of maxillary anterior teeth. The height of the support frame 6 is adapted to the height of the maxillary anterior teeth. Since the main tongue spring member 4 applies a force to the maxillary anterior teeth from the inner side to the outer side, it is easy to cause the maxillary anterior teeth to tilt outward. To avoid this situation, by providing the support frames 6, the vertical inclination of the maxillary anterior teeth can be restricted, and then the situation of the maxillary anterior teeth tilting outward can be avoided.

[0032] Referring to Figure 8 , the connector 7 includes a housing 71. A slider 73 is arranged inside the housing 71. An anti-detachment column 72 is fixedly connected to the inner wall of the housing 71. The slider 73 is slidably sleeved on the side wall of the anti-detachment column 72. The slider 73 is in transmission connection with the inner wall of the housing 71 through a spring 74. One end of the arc-shaped rod 5 is connected to the slider 73. When correcting the "underbite" condition of the teeth, the maxillary anterior teeth will move outward. The support frame 6 abuts against the outer side of the maxillary anterior teeth, which restricts the outward movement of the teeth. To avoid this situation, due to the connection relationship between the slider 73 and the anti-detachment column 72, the arc-shaped rod 5 can move synchronously with the teeth, thereby avoiding the support frame 6 from affecting the correction of the "underbite".

[0033] The working principle of the present utility model: In the original existing orthodontic appliance, the tongue arch assembly 1 abuts against the maxillary anterior teeth before to develop outward, achieving the effect of correcting the "underbite". A plurality of main tongue spring members 4 are arranged on this structure. By the plurality of main tongue spring members 4 respectively contacting a plurality of maxillary anterior teeth, under the elastic effect of the S-shaped elastic piece 41, the cross bar 42 forms an abutting effect on the anterior teeth, thereby restricting the torsion situation that occurs during the development of the maxillary anterior teeth. While the orthodontic appliance corrects the "underbite", it can also achieve the prevention and correction of the torsion problem of the maxillary anterior teeth;

[0034] By splitting the traditional tongue arch component 1 into two parts, namely the main tongue arch 11 and the telescopic connecting piece 13, the position of the maxillary anterior teeth is corrected by abutting against the main tongue arch 11. The main tongue arch 11 and the side-fixed tongue arch 12 are connected by the telescopic connecting piece 13. Through the telescopic effect of the telescopic connecting piece 13, the abutting pressure of the tongue arch component 1 on the maxillary anterior teeth can be adjusted, thus avoiding the problem of poor orthodontic treatment caused by improper installation.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. The present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
