AI Technical Summary
In the prior art, when correcting tongue tilt molars, commonly used upper and lower jaw interttraction methods may cause the teeth to elongate vertically, increasing the complexity of opening and closing of the anterior teeth, and the traditional single-tooth mini spiral expander occupying too much oral space, resulting in Discomfort.
A corrector including a double-arm elastic arm, a plastic base, a hyperbolic lip arch and an arrow snap ring was designed. Using the high elasticity characteristics of Australas material, the double-arm elastic arm is a V-shaped structure and the middle is twisted into a spiral structure. Increase the correction force, compact structure and take up less space.
It achieves a soft and lasting correction effect, reduces the increase in the vertical height of the teeth, and improves comfort and ease of operation.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molar correction appliances, in particular to a correction appliance for correcting lingually inclined molars. Background Art
[0002] In orthodontic clinics, we often encounter locking problems caused by lingual inclination of the mandibular second molar due to abnormal dental arch width. The occlusal relationship of the molars affects the trajectory of mandibular movement and the body's avoidance mechanism, which may cause muscle dysfunction and temporomandibular joint disorder, and may also cause periodontal disease due to force in the wrong direction.
[0003] In order to solve the problem of molar lingual tilt, the method of inter-mandibular traction is often used in clinic. This method has certain limitations. For example, the vertical component of inter-mandibular traction will cause the molar to elongate and be higher than the occlusal plane. This molar elongation may cause the anterior teeth to open and bite, making the correction more complicated. To solve this problem, we need a correction that can straighten the molars without increasing the vertical height of the teeth too much.
[0004] There are also some orthodontic appliances with similar mechanics in clinical practice. For example, a single-tooth mini spiral expander is placed on the lingual side of the lingually inclined tooth, with the rest of the dentition serving as retention and support. However, since the expander needs to be embedded, the embedded base will still occupy too much space for the free movement of the tongue in the oral cavity, causing discomfort. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a corrector for lingually inclined molars. The high elasticity of orthodontic Australian wire is used to make a double-arm elastic arm structure. This structure has soft and durable strength, only requires a small amount of space, is more comfortable, has a simple structure, and is easy for doctors to operate.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] An orthodontic appliance for correcting lingually tilted molars comprises a double-arm elastic arm, a plastic base, a hyperbolic lip bow and an arrowhead clasp;
[0008] The labial bow of the hyperbolic labial bow is welded to the buccal side of the arrowhead clamp;
[0009] The labial arch of the hyperbolic labial arch hyperbolicly crosses the interdental space of the premolars;
[0010] The arrowhead clasp is located on the first molar;
[0011] The plastic base is embedded in the interdental space of the posterior teeth;
[0012] The two arms of the double-arm elastic arm are both V-shaped structures as a whole, one end of the two arms is an integrally formed structure, the other end of the two arms is a hook-shaped structure, and the middle parts of the two arms are twisted into a spiral structure;
[0013] The middle parts of the two arms of the double-arm elastic arm are twisted to form a spiral structure, and a force-added structure is adopted to increase the correction force.
[0014] The double-arm elastic arms, the hyperbolic lip bow and the arrowhead clamp ring are all embedded in the plastic base.
[0015] The plastic base plays a role in embedding and connecting the double-arm elastic arms, the hyperbolic lip bow and the arrowhead clamp.
[0016] Preferably, one end of the double-arm elastic arm is sleeved on the gap between the posterior teeth, and the other end of the double-arm elastic arm is hung on the hyperbolic lip bow.
[0017] Preferably, the double-arm elastic arms, the hyperbolic lip bow and the arrowhead clamp are all formed by bending Australian wire.
[0018] The beneficial effects of the utility model are:
[0019] The corrector for correcting lingually inclined molars proposed by the utility model utilizes the high elasticity of Australian wire to form a double-arm elastic arm structure. This structure has gentle and durable force, requires only a small amount of space, is more comfortable, has a simple structure, and is easy for doctors to operate. BRIEF DESCRIPTION OF THE DRAWINGS
