Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to a novel tongue reed orthodontic appliance. Background Technology

[0002] Anterior crossbite is a relatively common malocclusion in clinical practice, which seriously affects the development of the maxillofacial region, oral function and aesthetics. Moreover, it tends to worsen progressively with the growth and development of the jawbone. Therefore, it should be corrected as early as possible to release the locking relationship of the anterior teeth, so as to facilitate the normal growth trend of the upper and lower jaws and prevent the occurrence or development of skeletal anterior crossbite.

[0003] To address the aforementioned problems, the existing technology, as disclosed in CN219579082U, discloses a multi-curved lingual spring orthodontic appliance comprising: a novel anterior lingual spring, connecting blocks, posterior occlusal pads, interproximal hooks, and a transparent base, enabling the correction of anterior crossbite while wearing the transparent base. The curved structure on the novel anterior lingual spring releases force that propels the anterior teeth forward; by adjusting the number and size of the curved structures, the magnitude of the pushing force can be adjusted. Multiple novel anterior lingual springs effectively improve the efficiency of anterior tooth forward movement. The posterior occlusal pad can be configured as a single pad or a combined pad according to the patient's treatment needs; the combined pad connects multiple teeth together, effectively enhancing the retention of the posterior teeth. The connecting structure composed of the pads, interproximal hooks, and transparent base is fixed to the posterior teeth, enhancing the retention between the posterior teeth and the appliance. It is comfortable to wear and has a high degree of fit. In this design, the wire that holds the front teeth together with the connecting block is prone to breakage, and the wire tends to shift towards the incisal edge when force is applied, reducing the effectiveness of orthodontic treatment. Therefore, a new type of tongue reed appliance is proposed to address these issues. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A novel lingual spring orthodontic appliance includes a transparent base for covering the posterior segment of a dental model, a novel anterior lingual spring with adjustable elasticity, a connecting block, and a pressure bar disposed on the front side of the novel anterior lingual spring. The connecting block is installed inside the transparent base. One end of the novel anterior lingual spring is connected to the interior of the connecting block, and the other end abuts against the lingual side of the anterior teeth. The bottom end of the pressure bar is connected to the interior of the connecting block, and the rear side of the pressure bar presses against the front side of the novel anterior lingual spring. The anterior teeth are fixed to the rear end of the dental model. Interproximal hooks are installed inside both ends of the transparent base and are fixed to the outer side of the posterior teeth in the posterior segment of the dental model. The novel anterior lingual spring includes a long straight wire that fits against the front side of the anterior teeth. The right end of the long straight wire is connected to the left end of a first spring coil. The left end of the first spring coil is connected to the right side of a second spring coil. The bottom of the second spring coil is fixedly connected to the top of a spring. A connecting wire is provided at the bottom of the spring, and the bottom of the connecting wire is connected to the interior of the connecting block.

[0006] Preferably, the number of novel anterior lingual springs is determined based on the number of teeth in the patient's underbite or deviated lingually.

[0007] Preferably, the spring bends 2 or 3 turns.

[0008] Preferably, the end of the long straight steel wire that is not connected to the first spring coil has a smooth arc-shaped surface.

[0009] Preferably, a occlusal pad is provided at the connection between the transparent base and the posterior segment of the overlay dental model. The occlusal pad in the posterior tooth area is used to elevate the bite, release the reverse locking relationship, and allow the reverse-occlusal teeth to be pushed out smoothly by the tongue spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) The long straight steel wire is stretched outward. After the long straight steel wire is stretched outward, the first spring coil and the second spring coil will be stretched apart. After being stretched apart, the long straight steel wire will be more elastic when compressed. The pressure rod will press down the entire new anterior tooth lingual spring. The long straight steel wire is pushed against the front side of the anterior teeth. The orthodontic effect on the teeth is increased by increasing the elasticity. Attached Figure Description

[0019] Please see Figure 1-4 This utility model provides an embodiment of a novel lingual spring orthodontic appliance, comprising a transparent base 6 for covering the posterior segment of a dental model 1, a connecting block 7, and a pressure bar 8 disposed on the anterior side of a novel anterior lingual spring 4. The connecting block 7 is installed inside the transparent base 6. One end of the novel anterior lingual spring 4 is connected to the interior of the connecting block 7, and the other end abuts against the anterior side of the anterior tooth 5. The rear side of the pressure bar 8 presses against the lingual side of the novel anterior lingual spring 4. The anterior tooth 5 is fixed to the rear end of the dental model 1. Interproximal hooks 2 are installed inside both ends of the transparent base 6, and the interproximal hooks 2 are fixed to the outer side of the posterior teeth 3 in the posterior segment of the dental model 1. The novel anterior lingual spring 4 includes a long straight wire 41 that fits against the anterior side of the anterior tooth 5. The long straight wire 41 is used to abut against the anterior side of the anterior tooth 5. On the side, the right end of the long straight steel wire 41 is connected to the left end of the first spring coil 42, and the left end of the first spring coil 42 is connected to the right side of the second spring coil 43. The bottom of the second spring coil 43 is fixedly connected to the top of the spring 44. The bottom of the spring 44 is provided with a connecting wire 45, and the bottom of the connecting wire 45 is connected to the inside of the connecting block 7. The long straight steel wire 41 can be stretched outward. After the long straight steel wire 41 is stretched outward, the first spring coil 42 and the second spring coil 43 will be stretched apart. After being stretched apart, the long straight steel wire 41 will be more elastic when compressed. The pressure rod 8 presses down the entire new anterior lingual spring 4, and the long straight steel wire 41 is pressed against the front side of the anterior teeth 5. By increasing the elasticity, the orthodontic effect on the teeth is increased.

[0020] The number of new anterior lingual springs 4 is determined based on the number of teeth in the patient's underbite or deviated to the lingual side.

[0021] The spring 44 has two or three turns of spiral. The end of the long straight steel wire 41 that is not connected to the first spring coil 42 has a smooth arc surface, which will not scratch the teeth.

[0022] A occlusal pad 9 is provided at the connection between the transparent base 6 and the posterior segment of the overlay dental model 1. The occlusal pad 9 is added to the posterior tooth area to elevate the bite, release the reverse locking relationship, and allow the reverse teeth to be pushed out smoothly through the tongue spring.

[0023] When in use, the transparent base 6 is installed on the dental mold 1, and the long straight wire 41 is stretched outward. After the long straight wire 41 is stretched outward, the first spring coil 42 and the second spring coil 43 will be stretched apart. After being stretched apart, the long straight wire 41 will be more elastic when compressed. The long straight wire 41 presses against the front side of the front teeth and will be more elastic when compressed, thus increasing the orthodontic effect on the teeth.
