AI Technical Summary
The existing multi-curved wire tongue spring orthodontic appliances for anterior teeth have a fixed curved front end structure, which cannot adapt to teeth of different shapes, resulting in problems such as local pressure or poor fit.
A multi-curved wire tongue reed appliance was designed, which adopts a moving seat and rotating seat structure on the push rod section. The position and angle of the arc-shaped pad are adjusted through the transmission component. Combined with a silicone anti-slip layer, it can adapt to different crown tilt angles. The connection stability is improved by spiral strips and barbs.
It achieves precise adaptation to different tooth shapes, avoids local pressure or poor fit, improves wearing comfort and stability, and reduces damage to teeth.

Abstract
Claims
1. A multi-curved spring lingual appliance comprising a plurality of multi-curved springs (1) for anterior teeth each mounted on a mounting block, characterized in that, The anterior tooth multi-curved wire (1) is divided into a fixed section (101), a multi-curved section (102), and a push rod section (103); The push rod section (103) is symmetrically fitted with movable seats (2), and each of the two movable seats (2) has an annular rotating groove. Each of the two rotating grooves is fitted with a rotating seat (3). Each of the two rotating seats (3) is fixedly installed with an arc-shaped pad (4). The side of each of the two arc-shaped pads (4) that abuts against the teeth is bonded with a silicone anti-slip layer (5). The fixed section (101) has a cylindrical cavity inside, and the cylindrical cavity is provided with a transmission component for driving the two movable seats (2) to slide relative to each other.
2. A multi-serpentine lingual spring appliance according to claim 1, wherein, The push rod section (103) has a strip-shaped opening on its side that communicates with the cylindrical cavity. The transmission assembly includes two movable blocks (6) symmetrically installed in the cylindrical cavity by adjusting components and two sliding blocks (7) respectively fixedly installed on the two movable blocks (6). The two sliding blocks (7) slide horizontally in the strip-shaped opening, and one end is fixedly connected to the inner wall of the two movable seats (2) respectively.
3. A multi-serpentine lingual spring appliance according to claim 2, wherein, The adjusting component includes a threaded rod (8) with opposite helical directions at its left and right ends, which is horizontally rotatably installed in the cylindrical cavity, and an adjusting block (9). One end of the threaded rod (8) passes through the cylindrical cavity and is fixedly connected to the adjusting block (9). The two moving blocks (6) are symmetrically threaded onto the threaded rod (8).
4. A multi-serpentine lingual spring appliance according to claim 1, wherein, One of the arc-shaped pads (4) has a positioning block (10) symmetrically fixedly installed on one side, and the other arc-shaped pad (4) has a positioning groove (11) symmetrically opened on one side. The distance between the two positioning blocks (10) is the same as the distance between the two positioning grooves (11). The two positioning blocks (10) are located between the two arc-shaped pads (4).
5. A multi-serpentine lingual spring appliance according to claim 1, wherein, The fixed section (101) is spirally fitted with a spiral strip (12), which is embedded in the mounting block.
6. A multi-serpentine lingual spring appliance according to claim 5, wherein, Multiple V-shaped barbs (13) are fixedly installed at equal intervals around one end of the fixed section (101), and one end of the barbs (13) is fixedly connected to one end of the fixed section (101).
