Abstract
Description
Technical Field
[0001] This utility model relates to the field of orthodontic technology, specifically to invisible orthodontic appliances. Background Technology
[0002] An orthodontic appliance is a device used to treat malocclusion. It can generate force, or the functional force of the masticatory muscles and perioral muscles, to change the deformed jawbone, misaligned teeth, and periodontal supporting tissues, so as to facilitate the normal growth and development of the dentofacial region.
[0003] Existing orthodontic appliances typically utilize occlusal pads to elevate the bite, along with the alternating traction of stainless steel archwires and elastic bands, to achieve orthodontic treatment. However, the structure of occlusal pads that elevate the bite can easily affect patient comfort and chewing efficiency, resulting in a poor user experience. Utility Model Content
[0004] In view of this, the present invention provides an invisible orthodontic appliance to solve the problem that traditional orthodontic appliances use occlusal pads to raise the bite, which affects the patient's comfort and chewing efficiency, resulting in a poor user experience.
[0005] This utility model provides an invisible orthodontic appliance, comprising:
[0006] The maxillary braces have multiple first posterior braces spaced apart.
[0007] The mandibular braces have multiple second posterior braces spaced apart and are used in conjunction with the maxillary braces.
[0008] At least one posterior tooth guide is disposed on the side wall of the first posterior tooth bracket and / or the side wall of the second posterior tooth bracket, and the posterior tooth guide is adapted to correspond to the posterior tooth to be treated;
[0009] The invisible orthodontic appliance has a positive occlusal state and / or a negative occlusal state. In the positive occlusal state, each posterior tooth guide is located on the buccal side of the second posterior occlusal body and can contact the lingual tip of the first posterior occlusal body. In the negative occlusal state, each posterior tooth guide is located on the buccal side of the first posterior occlusal body and can contact the lingual tip of the second posterior occlusal body.
[0010] Beneficial Effects: This invention features posterior tooth guides on the sidewalls of the first and / or second posterior aligners, replacing traditional occlusal pads to elevate the occlusal structure. This avoids the interference of occlusal pads, improving patient comfort and experience. For patients with orthognathic occlusion, in the orthognathic state, the lingual cusps of the maxillary posterior teeth can directly bite onto the posterior tooth guides. With each chewing action, the posterior tooth guides assist in the intrusion of the maxillary posterior teeth, achieving orthognathic correction without affecting chewing. Similarly, for patients with reverse occlusion, in the reverse occlusion state, the lingual cusps of the mandibular posterior teeth can directly bite onto the posterior tooth guides. With each chewing action, the posterior tooth guides assist in the intrusion of the mandibular posterior teeth, achieving reverse occlusion correction.
[0011] In one alternative implementation, the posterior tooth guide is provided with an occlusal plane, the width of which does not exceed the width of the posterior tooth to be treated. In the orthodontic state, the occlusal plane can contact the lingual tip of the first posterior tooth guide body, and in the reversed occlusal state, the occlusal plane can contact the lingual tip of the second posterior tooth guide body.
[0012] Beneficial effects: During orthodontic treatment, the patient's teeth will move slowly to achieve the desired therapeutic effect. The lingual tip of the first or second posterior brace will contact the posterior guide at different positions. Because the posterior guide contacts the lingual tip of the first or second posterior brace through the occlusal plane, it avoids contact between the sharp parts of the posterior guide and the lingual tip of the first or second posterior brace, further improving the patient's experience.
[0013] In one alternative implementation, the occlusal plane extends along the width direction of the first or second posterior brace.
[0014] Beneficial effects: The occlusal plane extends along the width of the first or second posterior brace, facilitating its fit with the teeth to be treated.
[0015] In one alternative implementation, the width of the occlusal plane on the side closest to the first or second posterior brace gradually narrows from the side of the occlusal plane away from the first or second posterior brace.
[0016] Beneficial effects: The occlusal plane is wider on the side closer to the first or second posterior brace, which improves the connection strength between the posterior guide and the first or second posterior brace. The occlusal plane is narrower on the side away from the first or second posterior brace, which can reduce the size of the posterior guide and improve patient comfort.
[0017] In one alternative implementation, the posterior tooth guide is cube-shaped, with one side surface of the cube serving as the occlusal plane.
[0018] Beneficial effects: The posterior tooth guide is cubic in shape, with one side surface of the cube serving as the occlusal plane, which can provide good support and improve the structural strength of the posterior tooth guide.
[0019] In one alternative implementation, the posterior tooth guide is a flat cube or a circular cube.
[0020] Beneficial effects: The flat cube or round cube shape of the posterior tooth guide simplifies the structure of the posterior tooth guide while ensuring its structural strength, making it easier to process and manufacture, and reducing the cost of use.
[0021] In one optional implementation, multiple posterior tooth guides are provided, each corresponding to a multiple first posterior tooth bracket and / or a multiple second posterior tooth bracket, and are adapted to correspond one-to-one with multiple posterior teeth to be treated.
[0022] Beneficial effects: This utility model can be customized according to the patient's condition. Each posterior tooth to be treated is provided with a posterior tooth guide. The position of the posterior tooth guide can be adjusted according to the patient's condition, further improving the patient's user experience.
[0023] In one alternative implementation, the posterior tooth guide is integrally formed with the maxillary or mandibular brace.
[0024] Beneficial effects: The posterior tooth guide is integrally molded with the maxillary or mandibular brace, which further improves the structural strength of the posterior tooth guide and reduces the difficulty of processing and manufacturing.
[0025] In one alternative implementation, the maxillary braces and / or mandibular braces are provided with multiple weight-reducing cavities.
[0026] Beneficial effects: The upper and / or lower jaw braces have multiple weight-reducing cavities inside, which can reduce the weight of the upper and / or lower jaw braces and reduce the pressure and discomfort of the braces on the teeth and soft tissues of the cavity.
[0027] In one alternative implementation, the maxillary and mandibular braces are transparent braces.
[0028] Beneficial effects: The upper and lower braces are transparent, similar in color to teeth, making them more discreet and aesthetically pleasing. Additionally, they are easy to clean, preventing food debris from accumulating inside the braces and promoting good oral hygiene. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0035] In clinical practice, due to genetic factors, bad habits, or problems with tooth eruption, adult or adolescent patients may experience ectopic occlusion on the buccal or lingual sides of the upper and lower posterior teeth, resulting in either orthognathic or antignathic occlusion. Both orthognathic and antignathic occlusion reduce chewing efficiency and require timely treatment. Otherwise, incorrect occlusion can easily lead to joint problems, resulting in malocclusion, facial asymmetry, and other issues.
[0036] Traditional orthodontic appliances correct orthodontic problems by using occlusal pads to elevate the bite and the interaction of stainless steel archwires and elastic bands. However, this structure offers a poor user experience. This invention addresses this by incorporating posterior tooth guides on the sidewalls of the first and / or second posterior aligners, thus avoiding the interference of the occlusal pads and improving patient comfort and experience.
[0037] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.
[0038] According to embodiments of the present invention, such as Figure 1As shown, an invisible orthodontic appliance is provided, mainly comprising: an upper aligner 1, a lower aligner 2, and at least one posterior guide 3. The upper aligner 1 has multiple first posterior tooth bodies 101 spaced apart. The lower aligner 2 has multiple second posterior tooth bodies 201 spaced apart and is used in conjunction with the upper aligner 1. The posterior guide 3 is correspondingly disposed on the lateral wall of the first posterior tooth body 101 and / or the lateral wall of the second posterior tooth body 201, and the posterior guide 3 is adapted to correspond to the posterior teeth to be treated.
[0039] The invisible orthodontic appliance has a positive interlocking state and / or a negative interlocking state. In the positive interlocking state, each posterior tooth guide 3 is located on the buccal side of the second posterior aligner 201 and can contact the lingual tip of the first posterior aligner 101. In the negative interlocking state, each posterior tooth guide 3 is located on the buccal side of the first posterior aligner 101 and can contact the lingual tip of the second posterior aligner 201.
[0040] In this embodiment of the invention, a posterior tooth guide 3 is provided on the side wall of the first posterior aligner 101 and / or the side wall of the second posterior aligner 201, replacing the traditional occlusal pad to elevate the occlusal structure. This avoids the interference of the occlusal pad and improves patient comfort and experience. For patients with orthognathic occlusion, when the invisible aligner is in orthognathic occlusion, the lingual tip of the maxillary posterior teeth can directly bite onto the posterior tooth guide 3, such as... Figure 2 As shown. At this time, the other first posterior tooth body 101 and second posterior tooth body 201 of the maxillary braces 1 and mandibular braces 2 without the posterior tooth guide 3 are not in contact. With each chewing occlusion, the posterior tooth guide 3 can assist in the intrusion of the maxillary posterior teeth to achieve orthognathic surgery without affecting chewing.
[0041] Similarly, for patients with crossbite, when the clear aligner is in the crossbite state, the lingual tip of the mandibular posterior teeth can directly bite onto the posterior guide 3. At this time, the other first posterior tooth body 101 and second posterior tooth body 201 of the maxillary aligner 1 and mandibular aligner 2, which do not have the posterior guide 3, do not contact each other. With each chewing and biting action, the posterior guide 3 can assist in the intrusion of the mandibular posterior teeth, thus achieving crossbite correction.
[0042] Compared to traditional orthodontic appliances, this embodiment of the invention eliminates the need to replace the square wires. It utilizes the combined forces of the maxillary braces 1 and mandibular braces 2 to correct locked occlusion, significantly shortening treatment time. Furthermore, this embodiment does not require raising the bite; after the removal of the maxillary braces 1 and mandibular braces 2, the other teeth can still maintain a uniform bite, resulting in better comfort.
[0043] Specifically, the posterior tooth guide 3 of this embodiment can be installed only on the first posterior tooth bracket 101 to correct patients with reverse overbite, or only on the second posterior tooth bracket 201 to correct patients with orthognathic overbite, or simultaneously on both the first and second posterior tooth brackets 101 and 201 to simultaneously correct patients with both orthognathic and reverse overbite. Each first posterior tooth bracket 101 needs to correspond one-to-one with the patient's maxillary posterior teeth, and each second posterior tooth bracket 201 needs to correspond one-to-one with the patient's mandibular posterior teeth. The maxillary bracket 1 and mandibular bracket 2 can also be provided with other brackets to completely cover all of the patient's teeth.
[0044] It should be noted that posterior occlusion refers to the buccal cusp of the maxillary posterior teeth covering the buccal slope of the buccal cusp of the mandibular posterior teeth. Orthognathic occlusion refers to the lingual slope of the maxillary posterior teeth biting onto the buccal side of the buccal slope of the mandibular posterior teeth, with no occlusal contact on the occlusal surfaces. Reverse occlusion refers to the lingual slope of the mandibular posterior teeth biting onto the buccal slope of the maxillary posterior teeth, with no occlusal contact on the occlusal surfaces.
[0045] In one embodiment, the posterior tooth guide 3 is provided with an occlusal plane. The width of the occlusal plane does not exceed the width of the posterior tooth to be treated. In the orthodontic state, the occlusal plane can contact the tip of the tongue of the first posterior tooth bracket 101. In the reversed occlusal state, the occlusal plane can contact the tip of the tongue of the second posterior tooth bracket 201.
[0046] During orthodontic treatment, the patient's teeth will move slowly to achieve the desired therapeutic effect. The lingual tip of the first posterior brace 101 or the second posterior brace 201 will contact the posterior guide 3 at different positions. Because the posterior guide 3 contacts the lingual tip of the first posterior brace 101 or the second posterior brace 201 through the occlusal plane, it avoids contact between the sharp parts of the posterior guide 3 and the lingual tips of the first posterior brace 101 or the second posterior brace 201, further improving the patient's experience.
[0047] In one embodiment, the occlusal plane extends along the width of the first posterior brace body 101 or the second posterior brace body 201. This facilitates fitting with the teeth to be treated.
[0048] In one embodiment, the width of the occlusal plane on the side closest to the first posterior brace 101 or the second posterior brace 201 gradually narrows from the side of the occlusal plane away from the first posterior brace 101 or the second posterior brace 201.
[0049] The occlusal plane is wider on the side closer to the first posterior tooth bracket 101 or the second posterior tooth bracket 201 to improve the connection strength between the posterior tooth guide 3 and the first posterior tooth bracket 101 or the second posterior tooth bracket 201. The occlusal plane is narrower on the side away from the first posterior tooth bracket 101 or the second posterior tooth bracket 201 to reduce the size of the posterior tooth guide 3 and improve the patient's wearing comfort.
[0050] It should be noted that the present invention does not limit the shape and size of the posterior tooth guide 3.
[0051] In one embodiment, the posterior tooth guide 3 is cubic, with one side surface of the cube serving as the occlusal plane. This provides good support and improves the structural strength of the posterior tooth guide 3.
[0052] Furthermore, in one embodiment, the posterior tooth guide 3 is a flat cube or a circular cube. This simplifies the structure of the posterior tooth guide 3 while ensuring its structural strength, making it easier to manufacture and reducing usage costs.
[0053] It should be noted that the position and number of the posterior tooth guides 3 in this embodiment of the present invention need to be selected and set according to the patient's actual condition.
[0054] In one embodiment, multiple posterior tooth guides 3 are provided, and the multiple posterior tooth guides 3 correspond one-to-one with multiple first posterior tooth covers 101 and / or multiple second posterior tooth covers 201, and are suitable for corresponding one-to-one with multiple posterior teeth to be treated.
[0055] This utility model embodiment can be customized according to the patient's condition. Each posterior tooth to be treated is provided with a posterior tooth guide 3. The position of the posterior tooth guide 3 can be adjusted according to the patient's condition, further improving the patient's user experience.
[0056] In one embodiment, the posterior tooth guide 3 is integrally formed with the maxillary dental crown 1 or the mandibular dental crown 2. This further improves the structural strength of the posterior tooth guide 3 and reduces the difficulty of processing and manufacturing.
[0057] Specifically, the posterior tooth guide 3 and the maxillary brace 1 or the mandibular brace 2 are integrally formed by 3D printing and are made by pressing a high-polymer invisible material onto the model.
[0058] In one embodiment, the maxillary braces 1 and / or mandibular braces 2 are provided with multiple weight-reducing cavities. This can reduce the weight of the maxillary braces 1 and / or mandibular braces 2, thereby reducing the pressure and discomfort of the braces on the teeth and soft tissues of the cavities.
[0059] In one embodiment, the upper dental brace 1 and the lower dental brace 2 are transparent braces. Transparent braces are similar in color to teeth, making them more discreet and aesthetically pleasing. Furthermore, they are easy to clean, preventing food debris from accumulating inside the upper dental brace 1 and lower dental brace 2, thus promoting oral hygiene.
[0060] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
