Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dental aligners, and relates to a dental aligner with a removable lip bumper. BACKGROUND

[0002] In the field of orthodontics, early treatment of children and adolescents during the growth and development stage is particularly important. Considering the comfort and aesthetic needs of early treatment, more and more children choose to use the bracket-free invisible aligner technology to intervene in the early stage of problems such as abnormal tooth arrangement, jaw development disorder, or facial morphology abnormalities. However, bracket-free invisible aligner technology often needs to be combined with other auxiliary training devices such as lip bumpers to eliminate the adverse effects of abnormal lip muscle strength and to break bad oral habits such as lip biting to consolidate the treatment effect. The silicon lip bumper commonly used in clinical invisible aligner treatment is a removable silicon product, which is shaped like a small "lip shield". After the patient wears the invisible aligner, it is placed in the oral vestibule between the upper and lower jaws and the upper and lower lips. By using a physical barrier to correct the habit of biting the lips, reduce the abnormal pressure of the lips on the front teeth, and at the same time leave space for the growth of the alveolar bone and teeth. In addition, through the contraction of the lip muscle when the mouth is closed, the anchorage force of the molars can also be increased to prevent the molars from moving mesially. However, this lip bumper training device inevitably affects the patient's speech and normal life, and is often limited to daytime use, thereby limiting the treatment effect. In addition, due to the large volume of the integrated connection covering the labial side of the upper and lower anterior teeth, the wearing comfort is poor, which leads to increased resistance from patients with poor self-discipline, thereby further limiting the treatment effect. CN 201921075169.8 discloses a front tooth lip bumper force invisible aligner, which directly sets a lip bumper on the labial side of the front tooth crown cover area of the invisible aligner to form an integrated setting with the aligner, thereby increasing the comfort and convenience of the lip bumper and ensuring the wearing time. However, the non-removable nature of the lip bumper also causes difficulties in the patient's daily life. Because the setting of the lip bumper not only causes the patient's lips to protrude, thereby affecting the appearance, but also affects the speech, the invisible aligner requires the patient to wear it all day except when eating, which means that the patient cannot escape the shadow of the lip bumper during the daytime work and life or in certain specific situations.

[0003] Therefore, it is a technical problem to be solved to develop a comfortable invisible dental aligner with a removable lip bumper. SUMMARY

[0004] Due to the above-mentioned defects of the prior art, the present application provides an invisible dental aligner with a removable lip bumper, which is designed to be convenient to remove and wear, has an appropriate volume, and has strong comfort, thereby improving the patient's acceptance of the aligner and increasing the wearing time, thereby ensuring the treatment effect.

[0005] In order to achieve the above object, the present application provides a removable dental aligner with a lip bumper, characterized in that it comprises a dental aligner, a fixed button assembly and a lip bumper assembly.

[0006] The fixed button assembly is located at the gingival edge of the dental aligner, and comprises a connecting base and a fixed button; the connecting base is a cylinder with a diameter of 2.5-3.5 mm and a height of 0.5-1 mm, used for connecting the dental aligner and the fixed button; the fixed button is a cylinder with a diameter of 4.5-5.5 mm and a height of 1.5-2.5 mm, fixedly connected with the dental aligner through the connecting base.

[0007] The lip bumper assembly comprises a bumper and two fixed tubes; the bumper is an arc-shaped quadrilateral sheet with a thickness of 2-3 mm and a length equal to the total width of the dental crown of the maxillary or mandibular anterior teeth; the fixed tube is a hollow cylinder matched with the fixed button, located at the edge of the long side of the bumper and the corresponding position of the fixed button, used for fitting the fixed button.

[0008] The increased diameter and shortened height of the connecting base of the dental aligner ensure the connection strength, prevent the fixed button from breaking and falling off, and prolong the service life of the fixed button assembly; the appropriate volume of the fixed button assembly ensures the working strength and is used for fitting and fully fixing the lip bumper assembly; the appropriate length of the bumper enables the bumper to completely cover the labial side of the maxillary or mandibular anterior teeth, and the appropriate thickness ensures the treatment effect and avoids discomfort caused by excessive volume; the fixed tube is located at the edge of the bumper, which not only maximizes the effect of the reduced-volume bumper, but also avoids mutual interference when the upper and lower lip bumper assemblies are worn at the same time.

[0009] Further, the diameter of the connecting base is 3 mm, and the height is 1 mm; the diameter of the fixed button is 5 mm, and the height is 2 mm; the fixed tube is a hollow cylinder with an inner diameter of 5 mm, an outer diameter of 6 mm and a height of 2 mm. In this way, the lip bumper assembly and the fixed button assembly have sufficient fitting strength and are convenient for manual operation, and have little effect on the appearance of the patient.

[0010] Further, the material of the fixed button assembly is PETG (polyethylene terephthalate-1,4-cyclohexane dimethyl ester), which is a transparent, non-crystalline copolyester, and can be integrally formed with the commonly used dental aligner, so as to further improve the connection strength.

[0011] Further, the lip bumper assembly is a one-piece silicone hydrogel piece, which has high biological safety, high comfort and appropriate elastic performance, and is beneficial to repeated removal and oral retention of the lip bumper assembly.

[0012] Further, the horizontal extension line of the long side of the baffle is a tangent line of the outer circle of the fixed tube. In this way, not only can the baffle with a reduced volume maximize its role, but also can prevent mutual interference when the upper and lower jaw lip baffle assemblies are worn at the same time.

[0013] Further, the width of the baffle is 8-15 mm, and the appropriate width not only ensures the therapeutic effect, but also avoids the discomfort caused by the excessive volume.

[0014] Further, the width of the baffle is 10 mm, which is suitable for general population.

[0015] Further, the lip baffle assembly is arranged at least one of the upper jaw outer side and the lower jaw outer side to meet the treatment needs of different patients.

[0016] Compared with the prior art, the above-mentioned application has the following advantages or beneficial effects:

[0023] The structure of the present application will be further described below in conjunction with the drawings and specific embodiments, but not as a limitation of the present application.

[0024] Embodiment

[0025] Please see Figure 1 The present embodiment provides a removable lip bumper assembly for a clear aligner, which comprises a clear aligner 10 and a fixed elastic assembly 1 and a lip bumper assembly 2. Please see Figure 2 The fixed elastic assembly 1 is a PETG piece, which is located at the edge of the clear aligner 10 at the gum side of the canine crown cover. It comprises a connecting base 3 and a fixed elastic 4. The connecting base 3 is a cylinder with a diameter of 2.5-3.5 mm and a height of 0.5-1 mm. The preferred example is a cylinder with a diameter of 3 mm and a height of 1 mm, which is used to connect the clear aligner 10 and the fixed elastic 4. The increased diameter and the shortened height ensure the connection strength, thereby preventing the fixed elastic from breaking and falling off. The fixed elastic 4 is a cylinder with a diameter of 4.5-5.5 mm and a height of 1.5-2.5 mm. The preferred example is a cylinder with a diameter of 5 mm and a height of 2 mm, which is connected and fixed to the clear aligner 10 through the connecting base 3. The appropriate volume ensures the working strength and can be used to fit and fully fix the lip bumper assembly. The clear aligner and the fixed elastic assembly can be integrally formed. The interface between the connecting base 3 and the fixed elastic 4 of the fixed elastic assembly has an undercut structure, which can also be used to place the aligner set traction rubber band in the clear aligner, thereby reducing the number of fixed components of the aligner set traction rubber band and reducing the production cost of the aligner.

[0026] Please see Figure 3 The lip bumper assembly 2 is a silicone hydrogel piece, which comprises a baffle 5 and two fixed tubes 6 and can be integrally formed. The baffle 5 is a long rectangular sheet with four corners in an arc shape, with a thickness of 2-3 mm, and the preferred example is 3 mm. The length of the baffle 5 is the sum of the width of the crown of the maxillary or mandibular anterior teeth, so that the baffle can completely cover the labial side of the maxillary or mandibular anterior teeth. The width of the baffle 5 is 8-15 mm, preferably 10 mm. The appropriate length and width ensure the therapeutic effect while avoiding discomfort caused by excessive volume. The fixed tube 6 is an example of a hollow cylinder with an inner diameter of 5 mm, an outer diameter of 6 mm, and a height of 2 mm, which is used to fit the fixed elastic 4. The fixed tube 6 is located at the edge of the long side of the baffle 5, and the most optimal is that the horizontal extension line of the long side of the baffle 5 is the tangent line of the outer circle of the fixed tube 6. The fixed tube 6 is located at the edge of the baffle 5, which not only maximizes the role of the reduced volume of the baffle, but also prevents mutual interference when the upper and lower lip bumper assemblies are worn at the same time. The distance between the two fixed tubes 6 in the lip bumper assembly 2 is consistent with the distance between the two fixed elastics 4 of the corresponding maxillary or mandibular, so that the fixed tube 6 and the fixed elastic 4 are fitted, thereby realizing the fixation of the lip bumper assembly 2 on the clear aligner.

[0027] The use method of the removable lip bumper assembly of the above-mentioned clear aligner is as follows:

[0028] For patients such as the patients with mandibular retrusion and Angle II, mainly needing to use the lower lip bumper to break the adverse effects of lower lip tension, after wearing the invisible dental aligner 10, the side of the lower lip bumper assembly 2 with the fixing tube 6 is directed towards the mouth, the long edge of the baffle 5 where the fixing tube 6 is located is directed upwards, the lower lip bumper assembly 2 is worn into the mouth in this direction, and the two fixing tubes 6 are respectively matched with the two fixing buttons 4 on the lower invisible dental aligner and are sufficiently compacted, so that the lower lip bumper assembly 2 is fixed to the labial side of the lower invisible dental aligner.

[0029] For patients such as the patients with Angle III, mainly needing to use the upper lip bumper to break the adverse effects of upper lip tension, after wearing the invisible dental aligner 10, the side of the upper lip bumper assembly 2 with the fixing tube 6 is directed towards the mouth, the long edge of the baffle 5 where the fixing tube 6 is located is directed downwards, the upper lip bumper assembly 2 is worn into the mouth in this direction, and the two fixing tubes 6 are respectively matched with the two fixing buttons 4 on the upper invisible dental aligner and are sufficiently compacted, so that the upper lip bumper assembly 2 is fixed to the labial side of the upper invisible dental aligner.

[0030] For patients such as the patients with the habit of biting lips, needing the lip bumper to block the contact between the upper and lower lips and teeth, after wearing the invisible dental aligner 10, the side of the upper lip bumper assembly 2 with the fixing tube 6 is directed towards the mouth, the long edge of the baffle 5 where the fixing tube 6 is located is directed downwards, the upper lip bumper assembly 2 is worn into the mouth in this direction, and the two fixing tubes 6 are respectively matched with the two fixing buttons 4 on the upper invisible dental aligner and are sufficiently compacted, so that the upper lip bumper assembly 2 is fixed to the labial side of the upper invisible dental aligner. Then the side of the lower lip bumper assembly 2 with the fixing tube 6 is directed towards the mouth, the long edge of the baffle 5 where the fixing tube 6 is located is directed upwards, the lower lip bumper assembly 2 is worn into the mouth in this direction, and the two fixing tubes 6 are respectively matched with the two fixing buttons 4 on the lower invisible dental aligner and are sufficiently compacted, so that the lower lip bumper assembly 2 is fixed to the labial side of the lower invisible dental aligner.

[0031] In summary, the present application provides an invisible dental aligner containing a removable lip bumper, which is designed with high precision, is convenient to wear and remove, has a proper volume, is comfortable, can improve the acceptance of the aligner by patients, and thus increases the wearing time, so as to ensure the treatment effect.
