Description

Technical Field

[0001] This application relates to the technical field of oral orthodontics, and particularly relates to an adjustable oral orthodontic appliance. Background Art

[0002] In recent years, the problem of children's oral malformations has become increasingly serious, and the demand for orthodontics has gradually increased. Existing orthodontic appliances are relatively large in weight and volume, resulting in poor wearing comfort for patients, low compliance, and easy to fall out of the patient's mouth. In addition, the positions of the upper and lower dental alveoli of the current orthodontic appliance are relatively fixed and mostly integrally formed, with relatively poor adaptability, so that it cannot be adjusted according to the situation during the orthodontic process, resulting in poor treatment accuracy. Moreover, as the wearer grows and the orthodontic effect takes effect, the dental and maxillofacial bone conditions change continuously. To ensure the adaptability of the orthodontic appliance and meet the orthodontic needs, the orthodontic appliance generally needs to be replaced regularly, and each time the orthodontic appliance is replaced, the patient needs to cooperate to obtain corresponding orthodontic data, which increases the burden on the patient.

[0003] Therefore, how to reduce the cost of using orthodontic appliances, meet the orthodontic needs and improve the orthodontic effect has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0061] As Figures 1 to 7As shown in the figure, an embodiment of the present application provides an adjustable oral appliance, which includes: an upper alveolar body and a lower alveolar body constituting the main body of the appliance, a displacement angle adjustment component 2, a positioning component 3, and a tooth-shaped correction component 6. Among them, the upper alveolar body and the lower alveolar body are respectively set as segmented structures, and the alveolar sides 10 of the upper alveolar body and the lower alveolar body are set as hollow structures. The displacement angle adjustment component 2 is arranged between adjacent segmented upper alveolar bodies and between the lower alveolar bodies. By adjusting the displacement angle between the segmented upper alveolar body and the lower alveolar body through the displacement angle adjustment component 2, the required correction positions of the upper alveolar body or the lower alveolar body in each correction stage can be adjusted. The positioning component 3 is respectively arranged at the bottom of the grooves of the upper alveolar body and the lower alveolar body or inside their respective grooves. The tooth-shaped correction component 6 is connected to the positioning component 3 to achieve positioning under the action of the positioning component 3. Among them, the tooth-shaped correction component 6 is provided with tooth-shaped correction forms corresponding to each correction stage, and the tooth-shaped correction component 6 is formed by filling a plastic airbag with a silica gel colloid. When correcting the teeth in the current stage, the tooth-shaped correction component 6 in the current stage is positioned at the correction position on the alveolar sides 10 of the upper alveolar body and the lower alveolar body through the positioning component 3, so as to cover the grooves at the correction position through the tooth-shaped correction component 6 in the current stage to correct the teeth in the current stage. When correcting the teeth in the next stage, the tooth-shaped correction component 6 in the current stage is removed, and the tooth-shaped correction component 6 in the next stage is continuously positioned at the correction position through the positioning component 3, so as to cover the grooves at the correction position through the tooth-shaped correction component 6 in the next stage to correct the teeth in the next stage.

[0062] The specific structures of the various components of the oral appliance will be specifically described below.

[0063] In this embodiment, the upper alveolar body and the lower alveolar body are respectively set as segmented structures. Specifically, the upper alveolar body and the lower alveolar body respectively include a plurality of sub-upper alveolar bodies 11 and a plurality of sub-lower alveolar bodies 12. One sub-upper alveolar body 11 serves as a section structure of the upper alveolar body, and one sub-lower alveolar body 12 serves as a section structure of the lower alveolar body. The upper alveolar body is formed by splicing the respective sub-upper alveolar bodies 11, and the lower alveolar body is formed by splicing the respective sub-lower alveolar bodies 12. In one example, the number of the plurality of sub-upper alveolar bodies 11 and the plurality of sub-lower alveolar bodies 12 is equal, and at the positions opposite in the longitudinal direction, the length dimensions of each sub-upper alveolar body 11 and each sub-lower alveolar body 12 are equal. Of course, in other examples, the number of the plurality of sub-upper alveolar bodies 11 and the plurality of sub-lower alveolar bodies 12 is not equal, and at the positions opposite in the longitudinal direction, the length dimensions of each sub-upper alveolar body 11 and each sub-lower alveolar body 12 are not equal. Setting the upper alveolar body and the lower alveolar body as segmented structures respectively can realize the adjustment of the correction angles of the upper alveolar body and the lower alveolar body in different correction stages, so that it is not necessary to replace the entire new appliance main body corresponding to different correction stages.

[0064] In addition, in this embodiment, the alveolar sides 10 of the upper alveolar body and the lower alveolar body are provided with a hollow structure. The alveolar sides 10 of the upper alveolar body and the lower alveolar body are set as a hollow structure to facilitate the installation of the tooth-shaped correction component 6. Correspondingly, in one example, other parts of the upper alveolar body and the lower alveolar body may be provided with a hollow structure. Of course, in other examples, other parts of the upper alveolar body and the lower alveolar body may be provided with a solid structure. For example, the outer sides of the upper alveolar body and the lower alveolar body are solid structures to form a support for the main body of the orthodontic appliance.

[0065] The adjustment of the correction angles of the upper alveolar body and the lower alveolar body at different correction stages is achieved through the displacement angle adjustment component 2. Specifically, the displacement angle adjustment component 2 is arranged between adjacent segmented upper alveolar bodies and between adjacent segmented lower alveolar bodies (that is, the displacement angle adjustment component 2 is arranged between adjacent sub-upper alveolar bodies 11, and the displacement angle adjustment component 2 is arranged between adjacent sub-lower alveolar bodies 12). By adjusting the relative displacement angles of the segmented upper alveolar body and the lower alveolar body with the displacement angle adjustment component 2 (that is, adjusting the sub-upper alveolar body 11 with the displacement angle adjustment component 2, and adjusting the sub-lower alveolar body 12 with the displacement angle adjustment component 2), the required correction positions of the upper alveolar body or the lower alveolar body at each correction stage can be adjusted.

[0066] Furthermore, in this embodiment, the displacement angle adjustment component 2 includes: a connection positioning groove, a double-joint steering bearing 21, a connection support rod 22, and a displacement angle adjustment gear. Among them, the connection positioning groove is arranged between adjacent segmented upper alveolar bodies or lower alveolar bodies and is arranged oppositely along the longitudinal direction. Specifically, taking the upper alveolar body of the segmented structure as an example, the upper alveolar body includes a plurality of sub-upper alveolar bodies 11, and the connection positioning groove is arranged between adjacent sub-upper alveolar bodies 11. And in one example, the connection positioning groove includes a first connection positioning groove and a second connection positioning groove. Two adjacent sub-upper alveolar bodies 11 are called the first sub-upper alveolar body 11 and the second sub-upper alveolar body 11. The first connection positioning groove is arranged at opposite ends of the first sub-upper alveolar body 11 in the longitudinal direction, the second connection positioning groove is arranged at opposite ends of the second sub-upper alveolar body 11 in the longitudinal direction, and the first connection positioning groove and the second connection positioning groove are arranged in a staggered manner. In one example, the groove shapes of the first connection positioning groove and the second connection positioning groove are adapted to the circumferential end faces of the double-joint steering bearing 21.

[0067] The double-joint steering bearing 21 is clamped in the connection positioning groove. Among them, the double-joint steering bearing 21 includes a first-section steering bearing 211 and a second-section steering bearing 212. The first-section steering bearing 211 and the second-section steering bearing 212 are coaxially misaligned and can rotate independently relative to each other coaxially. The first-section steering bearing 211 is connected to the connection positioning groove (i.e., the first connection positioning groove) provided on the first side of the upper alveolar body or the lower alveolar body, so that the first sub-upper alveolar body 11 can rotate by being connected to the first-section steering bearing 211 through the first connection positioning groove. The second-section steering bearing 212 is connected to the connection positioning groove (i.e., the second connection positioning groove) provided on the second side of the upper alveolar body or the lower alveolar body, so that the second sub-upper alveolar body 11 can rotate by being connected to the second-section steering bearing 212 through the second connection positioning groove. In an example, the first side of the first sub-upper alveolar body 11 and the second side of the second sub-upper alveolar body 11 can form a corresponding orthodontic angle after rotation. Based on the coaxial misalignment of the first-section steering bearing 211 and the second-section steering bearing 212, the first connection positioning groove and the second connection positioning groove are misaligned and connected in the vertical direction on the circumferential end face of the double-joint steering bearing 21. The advantage of the misaligned connection is that it does not affect the circumferential rotation of the first sub-upper alveolar body 11 and the second sub-upper alveolar body 11 themselves, nor does it affect the circumferential rotation of the first sub-lower alveolar body 12 and the second sub-lower alveolar body 12 themselves.

[0068] The connection support rod 22 is connected between the relatively arranged double-joint steering bearings 21 to support the double-joint steering bearings 21. The displacement angle adjustment gear is provided on the double-joint steering bearing 21, and the double-joint steering bearing 21 is driven to rotate by adjusting the tooth pitch of the displacement angle adjustment gear. Correspondingly, the displacement angle adjustment gears are respectively provided on the first-section steering bearing 211 and the second-section steering bearing 212. The first-section steering bearing 211 is driven to rotate a first rotation angle correspondingly by adjusting the tooth pitch of the displacement angle adjustment gear, and the second-section steering bearing 212 is driven to rotate a second rotation angle correspondingly by adjusting the tooth pitch of the displacement angle adjustment gear. Among them, the first rotation angle and the second rotation angle are set according to the tooth correction angle required by the patient.

[0069] In an example, the displacement angle adjustment assembly 2 further includes: a positioning groove and a positioning protrusion, where the positioning groove is provided between adjacent segmented upper alveolar bodies or lower alveolar bodies. Specifically, the segmented structure corresponding to the upper alveolar body or the lower alveolar body includes the sub-upper alveolar body 11 or the sub-lower alveolar body 12, then the positioning groove is provided between adjacent sub-upper alveolar bodies 11 or sub-lower alveolar bodies 12. The positioning protrusion is provided on the displacement angle adjustment gear and can be clamped in the positioning groove. By providing the positioning groove and the positioning protrusion, the double-joint steering bearing 21 can be positioned after the double-joint steering bearing 21 rotates a corresponding angle, so that the sub-upper alveolar body 11 or the sub-lower alveolar body 12 driven to rotate can be fixed at the corresponding orthodontic angle.

[0070] In one example, the displacement angle adjustment assembly 2 further includes an adjustable connecting shaft (not shown), and the adjustable connecting shaft is arranged on two opposite sides of the upper alveolar body or the lower alveolar body. By adjusting the distance between the two opposite sides of the adjustable connecting shaft relative to the upper alveolar body or the lower alveolar body, the distance between the two opposite sides of the upper alveolar body or the lower alveolar body is adjusted. In this embodiment, corresponding to the structure of the upper alveolar body or the lower alveolar body, the upper alveolar body or the lower alveolar body respectively includes a sub-upper alveolar body 11 or a sub-lower alveolar body 12. Then, the adjustable connecting shaft is arranged on two opposite sides of the sub-upper alveolar body 11 or the sub-lower alveolar body 12. By adjusting the distance between the two opposite sides of the adjustable connecting shaft relative to the sub-upper alveolar body 11 or the sub-lower alveolar body 12, the distance between the two opposite sides of the sub-upper alveolar body 11 or the sub-lower alveolar body 12 is adjusted.

[0071] After determining and fixing the correction angle of the sub-upper alveolar body 11 or the sub-lower alveolar body 12, an adjusted orthodontic appliance main structure can be formed. Then, the correction positions of the alveolar sides 10 of the upper alveolar body and the lower alveolar body in the corresponding correction stage are adjusted through the positioning assembly 3 and the tooth-shaped correction component 6.

[0072] Specifically, the positioning assembly 3 is respectively arranged at the bottom of the groove or inside the groove body of the upper alveolar body and the lower alveolar body. The tooth-shaped correction component 6 is connected to the positioning assembly 3 to achieve positioning under the action of the positioning assembly 3. The tooth-shaped correction component 6 is provided with tooth-shaped correction morphologies corresponding to each correction stage, and the tooth-shaped correction component 6 is formed by filling a plastic airbag with a silica gel colloid. When correcting the teeth in the current stage, the tooth-shaped correction component 6 in the current stage is positioned at the correction position of the alveolar sides 10 of the upper alveolar body and the lower alveolar body through the positioning assembly 3, so as to cover the groove body at the correction position through the tooth-shaped correction component 6 in the current stage to correct the teeth in the current stage. When correcting the teeth in the next stage, the tooth-shaped correction component 6 in the current stage is removed, and the tooth-shaped correction component 6 in the next stage is continuously positioned at the correction position through the positioning assembly 3, so as to cover the groove body at the correction position through the tooth-shaped correction component 6 in the next stage to correct the teeth in the next stage.

[0073] Further, in one example, the positioning assembly 3 includes: a support bracket, a drive positioning assembly 32, a load-bearing flexible belt 4, and a plurality of first Velcro strips 51. The support brackets are respectively arranged on the inner side of each of the upper alveolar body and the lower alveolar body in a U-shaped structure, and are arranged at intervals in the extension direction of the upper alveolar body and the lower alveolar body. In one example, the interval distance between two adjacent support brackets can be close to the length distance of two adjacent sub-upper alveolar bodies 11 or sub-lower alveolar bodies 12. In one example, the support brackets are arranged on the inner side of the ends of the upper alveolar body and the lower alveolar body in a U-shaped structure and the inner side between the inner side of the ends of the upper alveolar body and the lower alveolar body and the inner side of the top end. The drive positioning assembly 32 is correspondingly arranged on the adjacent support brackets, and can be rotated and positioned relative to the support brackets.

Among them, the first end surface and the second end surface of the bearing flexible belt 4 refer to two end surfaces in the longitudinal direction, and the first end surface of the bearing flexible belt 4 is on the same side as the alveolar side 10, and the second end surface of the bearing flexible belt 4 is away from the alveolar side 10. For example, if there are three supporting flexible belts 4, then there are correspondingly three groups of first shaping airbags 61 and three groups of second shaping airbags 62, and one group of first shaping airbags 61 is arranged on the first end surface of one supporting flexible belt 4, and one group of second shaping airbags 62 is arranged on the second end surface of the supporting flexible belt 4.

Among them, the correction form includes a correction form for a part of the alveolar side 10 of the upper alveolar body and the lower alveolar body, and the correction form is a form that is embedded with the teeth and is arranged on the side facing the teeth. The installation form is a form installed with the alveolar body of the orthodontic device, and is arranged on the side away from the teeth. The shaping airbag can be embedded in the respective alveolar bodies of the upper alveolar body and the lower alveolar body through the installation form.

[0075] In the top-down direction, the first Velcro 51 is arranged between adjacent shaping airbags, and the shaping airbags abutting against the supporting flexible belt 4 are connected through the first Velcro 51. The first Velcro 51 is used to position the shaping airbags and to remove the shaping airbags at the current stage. When correcting the teeth at the current stage, the shaping airbags at the current stage located on the first end surface of the supporting flexible belt 4 are driven by the positioning assembly 32 to the correction position of the partial alveolar side 10 of the upper alveolar body and the lower alveolar body according to a predetermined distance, so that the shaping airbags at the current stage cover the partial alveolar side 10 of the correction position, so as to correct the teeth at the current stage. When correcting the teeth of the next stage, the shaping airbag of the current stage is removed, and the shaping airbag of the next stage located on the second end face of the bearing flexible belt 4 is continued to be driven by the driving and positioning component 32 to the correction position of the partial alveolar side 10 according to a predetermined distance, so that the shaping airbag of the next stage covers the partial alveolar side 10 of the correction position, so as to correct the teeth of the next stage. By analogy, when it is necessary to adjust the teeth of the corresponding stage, the shaping airbag of the corresponding stage located on the corresponding end face of the bearing flexible belt 4 can be driven by the driving and positioning component 32 to the correction position of the partial alveolar side 10 of the upper alveolar body and the lower alveolar body according to a predetermined distance, so that the shaping airbag of the corresponding stage covers the partial alveolar side 10 of the correction position, so as to correct the teeth of the corresponding stage, thereby eliminating the need to replace the entire appliance body.

In one example, the connecting shaft 323 is rotated by manual toggle. Or, in one example, the connecting shaft 323 is driven by a small stepping drive motor. When the small stepping drive motor drives the connecting shaft 323 to rotate, it can synchronously drive the supporting flexible belt 4 to rotate, thereby driving the tooth correction component 6 on the supporting flexible belt 4 to rotate synchronously. When it rotates to the position of the clamping knife 324, the first Velcro 51 can be separated by the clamping knife 324, and then the tooth correction component 6 of the previous stage can be automatically removed. The positioning structure 33 is arranged on the driving positioning wheel 321 and the wall of the upper alveolar body and the lower alveolar body, and is used to position the driving positioning wheel 321 after rotation. Further, in this embodiment, the positioning structure 33 includes: a limit groove 331, a spring 332, a groove pin 333 and a receiving groove 334.
