Description

Technical Field

[0001] This utility model relates to the field of oral training equipment technology, and in particular to an integrated orthodontic appliance that helps correct malocclusion. Background Technology

[0002] Underbite is a common malocclusion and is difficult to correct. Separate orthodontic appliances, due to their upper and lower jaw separate structures, require integration with intermaxillary force devices to adjust jaw position. Furthermore, the labial inclination of the anterior teeth relies on passive adjustment via external force, which can lead to poor expression and unstable treatment results.

[0003] Therefore, it is necessary to develop an integrated orthodontic appliance that helps correct underbite, so as to enable autonomous adjustment of the occlusal relationship and improve the stability of the orthodontic effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an integrated orthodontic appliance that helps correct malocclusion, enabling autonomous adjustment of the occlusal relationship and improving the stability of the orthodontic effect.

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated orthodontic appliance that helps correct malocclusion, including a jaw pad, a tongue guard formed on the inner side of the jaw pad, and a lower lip guard extending downward from the outer side of the jaw pad. The tongue guard, the jaw pad, and the lower lip guard form a lower dental alveolar groove. The top surface of the jaw pad is provided with a boss structure, and the boss structure is provided with an occlusal slope for contacting the lingual surface of the upper teeth. The occlusal slope extends from bottom to top toward the tongue guard.

[0006] As an improvement to the above solution, the engagement slope is provided with multiple slots extending from the top to the bottom.

[0007] As an improvement to the above solution, at least one of the slot width and slot depth gradually decreases from the top to the bottom.

[0008] As an improvement to the above solution, the boss structure includes a first boss and a second boss. The first boss is disposed opposite to the lower tooth groove, and the second boss is disposed opposite to the lower lip stop, or opposite to the lower tooth groove and the lower lip stop. The first boss protrudes towards the top surface of the second boss.

[0009] As an improvement to the above solution, the first boss is provided with a first engagement slope extending from bottom to top toward the tongue stop, and the second boss is provided with a second engagement slope extending from bottom to top toward the tongue stop.

[0010] As an improvement to the above solution, the projection of the first occlusal ramp in the vertical direction covers the top of the lower tooth groove.

[0011] As an improvement to the above solution, it also includes an upper lip stop, wherein the tongue stop, the jaw pad and the upper lip stop form an upper tooth groove, and the front end of the upper lip stop has a groove that communicates with the upper tooth groove.

[0012] As an improvement to the above solution, the groove extends through the top of the upper lip stop.

[0013] As an improvement to the above solution, the boss structure is positioned directly opposite the slot, or is located inside the slot.

[0014] As an improvement to the above solution, the tongue stop is provided with a tongue contact portion, which is located on the side of the boss structure away from the biting slope.

[0015] Implementing this utility model has the following beneficial effects:

[0016] This utility model discloses an integrated orthodontic appliance for correcting underbite. It features a lower jaw recess formed by a tongue guard, an occlusal pad, and a lower lip guard. A raised platform structure is provided on the top surface of the occlusal pad, with an occlusal ramp extending upwards towards the tongue guard. The tongue guard, occlusal pad, and lower lip guard are integrated, stabilizing the jaw position through the interaction of the upper and lower jaws. The lower lip guard prevents the mandible from moving further forward. Simultaneously, the raised platform structure on the top of the occlusal pad provides an occlusal ramp that adheres closely to the lingual surface of the upper teeth. As the wearer voluntarily bites, the occlusal ramp applies an outward force to the lingual surface of the upper teeth, guiding the underbite teeth to the correct overbite relationship, thus correcting the underbite. This orthodontic appliance, adjusted by the wearer's voluntary biting, further enhances stability after treatment. Attached Figure Description

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown, this utility model discloses a first embodiment of an integrated orthodontic appliance that helps correct an overbite, including an occlusal pad 1, a tongue guard 2 formed on the inner side of the occlusal pad 1, and a lower lip guard 3 formed extending downward from the outer side of the occlusal pad 1. The tongue guard 2, the occlusal pad 1, and the lower lip guard 3 form a lower alveolar groove a. The top surface of the occlusal pad 1 is provided with a boss structure, and the boss structure is provided with an occlusal slope for contacting the lingual surface of the upper teeth. The occlusal slope extends from bottom to top toward the tongue guard 2.

[0023] This embodiment features a lower dental alveolar 'a' formed by a tongue guard 2, a jaw pad 1, and a lower lip guard 3. A boss structure is provided on the top surface of the jaw pad 1, with an occlusal ramp extending upwards towards the tongue guard 2. The tongue guard 2, jaw pad 1, and lower lip guard 3 are integrated, stabilizing the jaw position through the interaction of the upper and lower jaws. The lower lip guard 3 prevents the lower jaw from moving forward further. Simultaneously, the boss structure on the top of the jaw pad 1 features an occlusal ramp that closely adheres to the lingual surface of the upper teeth. As the wearer voluntarily bites, the occlusal ramp applies an outward force to the lingual surface of the upper teeth, guiding the underbite teeth to the correct overbite relationship, thus correcting the underbite. This appliance, adjusted by the wearer's voluntary biting, enhances stability after treatment.

[0024] It should be noted that the upper teeth lingual surface refers to the surface of the upper teeth facing the tongue, while the upper teeth labial surface mentioned below refers to the surface of the upper teeth facing the lips.

[0025] The slope of the interlocking ramp can be set to 40~80°, preferably 45°, and can be set according to actual needs.

[0026] The occlusal ramp has multiple slots extending from the top to the bottom to vertically guide each upper tooth and help correct its growth direction. The depth and width of the slots are preferably gradually reduced from the top to the bottom. The greater the downward occlusal distance of the upper teeth, the greater the pressure exerted by the upper teeth on the occlusal ramp, which helps improve the orthodontic effect.

[0027] The protrusion structure in this embodiment specifically includes a first protrusion 11 and a second protrusion 12. The first protrusion 11 is disposed opposite to the lower alveolar ridge a, and the second protrusion 12 is disposed opposite to the lower lip guard 3, or opposite to both the lower alveolar ridge a and the lower lip guard 3. The first protrusion 11 protrudes towards the top surface of the second protrusion 12. The first protrusion 11 has a first occlusal slope 111 extending upward toward the tongue guard 2, and the second protrusion 12 has a second occlusal slope 121 extending upward toward the tongue guard 2. In this embodiment, the slot is preferably disposed on the first occlusal slope 111 of the first protrusion 11. The projection of the first occlusal slope 111 in the vertical direction covers the top of the lower alveolar ridge a, so that when the wearer bites with the first occlusal surface, it can also achieve the effect of correcting the underbite. The first protrusion 11 can extend to the palate to increase the working area of ​​the protrusion structure and the entire maxilla. The first protrusion 11 and the second protrusion 12 can be disposed in two or more layers as needed to form a continuous stepped structure. The height difference between the first protrusion 11 and the second protrusion 12, as well as the height difference between each second protrusion 12, is approximately 1 mm. Depending on the different stages of treatment, the wearer can adjust the lingual surface of the upper teeth to make occlusal contact with different first protrusions 11 or second protrusions 12, so that the upper teeth bite with the protrusion structure that is closer to the current tooth condition. At this time, the angle between the first occlusal inclination 111 or the second occlusal inclination 121 and the lingual surface of the upper teeth is small, making the wearer more comfortable during the treatment process and making the bite more stable. At the same time, according to the contact between the lingual surface of the upper teeth and different protrusion structures, it helps to understand the treatment progress of the reverse bite teeth and facilitates the monitoring of the reverse bite treatment process.

[0028] For anterior crossbite, the appliance in this embodiment also includes an upper lip guard 4, which extends upward from the outer side of the occlusal pad 1. The tongue guard 2, the occlusal pad 1, and the upper lip guard 4 form an upper alveolar ridge b, which is opposite to the lower alveolar ridge a. The tongue guard 2 forms a tongue receiving groove c, and the rear ends of the upper alveolar ridge b, lower alveolar ridge a, and tongue receiving groove c are all open. In this embodiment, the front end of the upper lip guard 4 has a slot d communicating with the upper alveolar ridge b, through which the upper crossbite in the anterior region passes. In this embodiment, the slot d extends through the top of the upper lip guard 4, and the boss structure is positioned directly opposite the slot d, or located within the slot d, to facilitate complete exposure of the labial surface of the upper crossbite in the anterior region and avoid obstruction of the labial surface of the upper crossbite in the anterior region.

[0029] For other areas of underbite, a slot d can be opened in the area of ​​the underbite to communicate with the upper alveolar bone b, so that the underbite upper teeth in that area can pass through, thus avoiding obstruction of the labial surface of the upper teeth of the underbite upper teeth in that area and better achieving underbite correction.

[0030] In addition, as needed, a tongue contact part 5 can be provided on the tongue guard part 2. The tongue contact part 5 is located on the side of the protrusion structure away from the occlusal slope, so as to train the tongue tip to lift and form muscle memory, so that the tongue can reach the correct tongue position of flat against the palate, and improve the situation where incorrect tongue position affects tooth development and alignment.

[0031] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
