Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically a dental occlusion pad tongue spring orthodontic appliance. Background Technology

[0002] Anterior crossbite during the primary and mixed dentition stages is one of the most common malocclusions in clinical practice. It not only affects the development of the maxillofacial region and normal oral function, but also has potential impacts on the child's mental and overall health. Occlusal pads with tongue springs are widely used and highly effective orthodontic appliances for correcting anterior crossbite. However, in existing occlusal pads with tongue springs, the tongue springs in the anterior region are individual units. During clinical application, there is a risk of the springs breaking off and being swallowed by the patient, increasing the clinical application risk and requiring improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an occlusal pad tongue spring orthodontic appliance.

[0004] The present invention adopts the following technical solution:

[0005] An occlusal pad and lingual spring orthodontic appliance includes an occlusal pad, a base, a combined lingual spring, and clasps. Two occlusal pads are provided, each fitting onto the occlusal surfaces of the two posterior teeth. The base is connected between the two occlusal pads. The combined lingual spring includes a base, an orthodontic section, and an elastic section. Two bases are provided and fixed within the base. The two ends of the orthodontic section correspond one-to-one with the two bases, abutting against the lingual surfaces of the reversed teeth, and its width is consistent with the width of the two protruding teeth. Two elastic sections are provided, each connecting the two bases to the two ends of the orthodontic section, giving the orthodontic section a tendency to always move forward. Each elastic section includes a first torsion spring and a second torsion spring connected end-to-end, with opposite helical directions. The first torsion spring is connected to the base, and the second torsion spring is connected to the orthodontic section. One side of the clasp is fixed within the base, and the other side extends and clamps onto the posterior teeth to secure the appliance.

[0006] Preferably, the occlusal pad includes an occlusal portion and a surrounding portion, the occlusal portion being located on the occlusal surface of the posterior teeth; the surrounding portion is connected to the occlusal portion near the lingual end, extending and forming along the palatal surface and palatal surface of the dental arch, and the base is connected to the surrounding portion on both sides.

[0007] Preferably, the clasp includes a starting segment, a transition segment, and a snap-fit ​​segment. Two starting segments are provided, which are disposed in the denture base and respectively opposite the first posterior tooth and the last posterior tooth. The transition segments are connected to the starting segments one by one, and extend outward through the mesial surface of the first posterior tooth and the distal surface of the last posterior tooth, respectively. The snap-fit ​​segment is connected between the ends of the two transition segments and extends along the buccal gingival margin of the posterior tooth to form a shape between the mesial surface of the first posterior tooth and the distal surface of the last posterior tooth.

[0008] Preferably, the transition section is located within the surrounding portion of the occlusal pad, and surrounds the entire palatal surface, palatal portion, and occlusal surface of the posterior teeth along with the occlusal pad.

[0009] Preferably, there are two combined lingual springs, symmetrically arranged in the denture base and facing the anterior teeth area, with the orthodontic portion of each combined lingual spring corresponding to the two anterior teeth on one side.

[0010] Preferably, the distance between the two second torsion springs in the combined tongue spring is the same as the distance between the two bases, the two first torsion springs are located between the two second torsion springs, the first torsion springs and the second torsion springs have the same structure but opposite helical directions, and the base ends are bent inward to connect with the first torsion springs.

[0011] Preferably, the combined tongue spring and the retaining ring are made of elastic materials.

[0012] Preferably, the pad and the base are made of polymer materials.

[0013] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are as follows: the corrective part of the combined tongue spring is opposite to the two front teeth, which can correct two reverse teeth at the same time. The two bases connected between the corrective parts are set in the occlusal pad. Even if one base breaks, the tongue spring will not be swallowed by the child. Compared with a single large T-shaped tongue spring, the combined tongue spring has a smaller span and is less likely to detach from the tooth surface after force is applied. The tongue spring can also be increased by the first torsion spring and the second torsion spring to provide a gentle and lasting corrective force. The magnitude and direction of the corrective force can also be adjusted by adjusting the angle or the number of coils of the first torsion spring and the second torsion spring. The point of action, direction of action and force value of the tongue spring are easy to control, making clinical application more convenient.

[0014] The orthodontic appliance achieves good retention and avoids slippage through the saliva adsorption and mechanical retention forces generated between the occlusal pad and the teeth, combined with the retention forces generated by the clasps. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below through specific embodiments.

[0021] Reference Figures 1 to 4 As shown, an occlusal pad tongue spring orthodontic appliance includes an occlusal pad 1, a base 2, a combined tongue spring 3, and a clasp 4.

[0022] Two occlusal pads 1 are provided, each fitting onto the occlusal surfaces of the posterior teeth. Occlusal pad 1 includes an occlusal portion 11 and a surrounding portion 12. The occlusal portion 11 is located on the occlusal surface of the posterior teeth, and the child's posterior teeth occlude on the occlusal portion 11. The surrounding portion 12 connects to the lingual end of the occlusal portion 11, extends along the palatal surface of the dental arch, and conforms to the inner surface of the posterior teeth and the dental arch, being fixed to the posterior teeth by salivary adhesion and mechanical tensile force. Occlusal pad 1 is made of self-curing resin.

[0023] The base 2 is positioned between the two mating pads 1, and its sides are connected to the surrounding portion 12. For example... Figure 1 As shown, when performing upper orthodontic treatment, the base 2 is placed on the surface of the upper tooth cavity, as... Figure 2 As shown, during mandibular orthodontic treatment, base 2 is placed at the inner gingival margin. The material of base 2 and occlusal pad 1 is the same self-curing resin.

[0024] Two combined tongue springs 3 are symmetrically positioned in the base 2 and facing the anterior teeth region. Each includes a base 31, an orthodontic section 32, and an elastic section 33. Two bases 31 are fixed in the base 2. The two ends of the orthodontic section 32 correspond one-to-one with the two bases 31, resting against the lingual surface of the occlusal teeth, with a width consistent with the width of the two front teeth. Each combined tongue spring 3's orthodontic section 32 corresponds to two front teeth on one side. Two elastic sections 33 are connected between the two bases 31 and the two ends of the orthodontic section 32, giving the orthodontic section 32 a tendency to always move forward. The combined tongue spring 3's orthodontic section 32 faces the two front teeth, allowing for the correction of two occlusal teeth simultaneously. The two bases 31 connected between the orthodontic sections 32 are placed in the occlusal pad 1, preventing accidental swallowing of the tongue spring even if one base 31 breaks. Compared to a single large T-shaped tongue spring, the combined tongue spring 3 has a smaller span, making it less prone to detaching from the tooth surface after force is applied.

[0025] The elastic part 33 includes a first torsion spring 331 and a second torsion spring 332 connected end to end. The first torsion spring 331 and the second torsion spring 332 have opposite helical directions. The first torsion spring 331 is connected to the base 31, and the second torsion spring 332 is connected to the correction part 32. The distance between the two second torsion springs 332 in the combined tongue spring 3 is the same as the distance between the two bases 31. The two first torsion springs 331 are located between the two second torsion springs 332. The first torsion springs 331 and the second torsion springs 332 have the same structure but opposite helical directions. The end of the base 31 is bent inward and connected to the first torsion spring 331. The magnitude and direction of the corrective force can be adjusted by adjusting the angle or the number of helical turns of the first torsion springs 331 and the second torsion springs 332. The point of action, direction of action, and magnitude of force of the tongue spring are easy to control, making clinical application more convenient. Compared with the structure of two traditional tongue springs, the combined tongue spring 3 does not add extra weight and will not reduce the wearing comfort of the orthodontic appliance. Specifically, the combined tongue spring 3 is a one-piece molded stainless steel wire.

[0026] One side of the clasp 4 is fixed within the base 2, while the other side extends and clamps onto the posterior teeth to secure the orthodontic appliance. The clasp 4 includes an initial segment 41, a transition segment 42, and a retaining segment 43. Two initial segments 41 are provided, positioned within the base 2 and corresponding to the first and last posterior teeth, respectively. The transition segments 42 connect one-to-one with the initial segments 41, extending outwards through the mesial surface of the first posterior tooth and the distal surface of the last posterior tooth, respectively. The retaining segment 43 connects the ends of the two transition segments 42, extending along the buccal gingival margin of the posterior teeth and forming a shape between the mesial surface of the first posterior tooth and the distal surface of the last posterior tooth. Specifically, the transition segment 42 is located within the surrounding portion 12 of the occlusal pad 1, and with the occlusal pad 1, it surrounds the entire palatal surface, palate, and occlusal surfaces of the posterior teeth of the dental arch. The salivary adhesion and mechanical retention forces generated between the occlusal pad 1 and the teeth, combined with the retention force generated by the clasp 4, ensure good retention of the orthodontic appliance, preventing slippage. The retaining ring 4 and the combined tongue spring 3 are made of the same material, which is a one-piece molded stainless steel wire.

[0027] In this application, a jaw model is first taken, and then a clasp 4 is made on the jaw model to fully fit the child's posterior tooth area. Next, a combined lingual spring 3 is made on the model. First, a 0.5mm-0.6mm stainless steel wire is taken, with a portion reserved in the middle of the wire to match the width of the child's two anterior teeth on one side. This portion is then bent inwards from both ends to form an orthodontic segment. Then, the orthodontic segment is spirally bent inwards from both ends to form a second torsion spring 332. Next, the two ends of the stainless steel wire are extended in opposite directions to a near position, and then spiraled in the opposite direction of the second torsion spring 332 to form a first torsion spring 331 (the orthodontic force can be adjusted by adjusting the number of spiral turns of the first torsion spring 331 and the second torsion spring 332). Finally, the end of the stainless steel wire is extended in the opposite direction to a position opposite to the ends of the orthodontic segment, and then in a direction perpendicular to the orthodontic segment. After installing the clasp 4 and the combined tongue spring 3 on the model, fix them with wax. Then, use self-curing resin to make the mat 1 and base 2 on the model. After the resin solidifies and is trimmed, the orthodontic appliance corresponding to the child can be obtained.

[0028] This application utilizes the structure of the first torsion spring 331 and the second torsion spring 332 within the combined tongue spring 3 to store more mechanical energy and release it slowly and persistently, resulting in a gentler and more lasting corrective force. Furthermore, both ends of the tongue spring are adjustable, making it easier to control the direction of force application. Even if one end of the combined tongue spring 3 breaks, the other end is embedded in the base 2, reducing the risk of accidental swallowing. Compared to ordinary hyperboloid tongue springs, there is no free archwire exposed in the oral cavity, reducing tongue irritation and making treatment more acceptable to patients. Moreover, since children undergoing early orthodontic treatment for reverse overbite are generally young, and their posterior teeth are usually primary teeth with short crowns, traditional removable orthodontic appliances using arrow-shaped clasps for single posterior teeth often struggle to achieve good retention. This application, however, provides good retention force through clasps 4 connected between the first and last posterior teeth, and the clasps are easy for patients to remove and insert.

[0029] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
