Description

Technical Field

[0001] The present invention relates to the field of dental orthodontics, and in particular to aesthetic fixed orthodontic appliances and combined orthodontic systems. Background Art

[0002] Metal and ceramic fixed appliances are commonly used in clinical orthodontic practice. These appliances utilize stainless steel archwires placed within the archwire slots of brackets to control tooth movement. However, these appliances have issues such as lack of aesthetic appeal, difficulty cleaning, and the tendency to accumulate tartar.

[0003] In addition to metal and ceramic brackets, fixed orthodontic appliances also include invisible removable appliances made of transparent polymer materials. These appliances were originally invented and manufactured by Align Technology in the United States. The greatest advantages of this type of appliance are ease of wear, ready access, minimal foreign body sensation, and a discreet, aesthetically pleasing appearance.

[0004] The inventors discovered that invisible braces and related technologies have difficulty controlling roots during clinical treatment, making them unsuitable for extractions and difficult cases, which often account for over 60% of orthodontic clinical tooth extractions. For common cases, invisible braces and related technologies require various accessories to move and control teeth during the correction process. Because invisible braces provide weak correction force and often fail during treatment, requiring reset, this not only prolongs the treatment cycle but also hinders the treatment process.

[0090] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0091] Reference Attachment Figure 1 To the attached Figure 28 As shown, the present application discloses an aesthetic fixed orthodontic appliance, comprising a body 100 and an archwire slot 200 passing through the body 100;

[0092] The main body 100 is an integral structure, and one side of the main body is a bonding surface 110 for connecting to the tooth surface, and the other side is an arcuate mating surface 120 for clamping other components; the arcuate mating surface 120 has relative mandibular side edges 121, gingival side edges 122, distal side edges 123 and mesial side edges 124, wherein the mandibular side edges 121 and the gingival side edges 122 are arranged opposite to each other and close to the bonding surface 110, and the middle part of the mandibular side edges 121 and the gingival side edges 122 is away from the bonding surface 110 to form a thickened portion 130, and the archwire slot 200 is arranged in the thickened portion 130 and passes through the distal side edges 123 and the mesial side edges 124.

[0093] The technical solution disclosed in this application realizes the multi-scenario application of dental arch wires and invisible braces through the optimized setting of aesthetic fixed orthodontic appliances, thereby taking into account the usage requirements in different treatment processes, improving the treatment process while enhancing the patient experience and the usage experience of medical staff.

[0094] For specific settings, refer to the attached Figure 1 To the attached Figure 4 In the embodiment shown, the thickness of the mandibular lateral edge 121 is less than or close to the thickness of the gingival lateral edge 122. The thickness is specifically expressed as the height formed relative to the bonding surface 110. The advantage of the above arrangement is that it can ensure that the transparent invisible braces can be easily removed. The mandibular lateral edge 121, the gingival lateral edge 122, the distal lateral edge 123 and the mesial lateral edge 124 are all matched with the bonding surface 110 through at least one stop plane 140. The maximum distance H1 between the arc-shaped matching surface 120 and the bonding surface 110 is located at the thickening portion 130, and the value range of H1 is 0.8 to 1.4 mm. The inner diameter D1 of the narrowest part of the archwire slot 200 is in the range of 0.4 to 0.6 mm. In a special embodiment, the ratio between D1 and H1 is in the range of 0.3 to 0.6. In the attached Figure 2In the embodiment, the archwire slot 200 has a circular cross-section, and therefore D1 is the diameter of the circle or its equivalent. In other embodiments, such as those with a square cross-section, D1 is the diameter of the inscribed circle of the square. The maximum distance H1 between the arcuate mating surface 120 and the bonding surface 110 is located at the thickened portion 130. In one particular embodiment, the ratio of the diameter D2 of the circumscribed circle of the bonding surface 110 to H1 ranges from 0.1 to 0.5. D2 herein refers to the diameter of the circumscribed circle of the bottom surface of the body 100 on the plane or curved surface where the bonding surface 110 is located.

[0095] In detail, the archwire slot 200 extends uniformly in its extension direction. Alternatively, as shown in the accompanying drawings, trumpet-shaped archwire introduction ports are provided at both ends of the archwire slot 200, near the distal side edge 123 and the mesial side edge 124. The cross-section of the archwire slot 200 is circular or rectangular.

[0096] As can be seen from the accompanying drawings, a central axis groove 150 is provided between the jaw side edge 121 and the gingival side edge 122, which is recessed or protruding compared to the arc-shaped mating surface 120. The extension direction of the central axis groove 150 intersects with the extension direction of the archwire slot 200. The central axis groove 200 is used to achieve positioning. In terms of the setting details of the central axis groove 150, the central axis groove 150 passes above the archwire slot 200. The central axis groove 150 is independent of the archwire slot 200 or is connected to the archwire slot 200. In terms of the specific size range, the opening width W1 of the central axis groove 150 ranges from 0.1 to 0.3 mm. The opening depth D3 of the central axis groove 150 ranges from 0.1 to 0.2 mm. In a particular embodiment, the ratio of the opening width W1 of the central axis slot 150 to the inner diameter D1 of the archwire slot 200 at its narrowest point is in a range of 0.1 to 1; and the ratio of the opening depth D3 of the central axis slot 150 to the inner diameter D1 of the archwire slot 200 at its narrowest point is in a range of 0.1 to 0.5.

[0097] Referring to the drawings, it can be seen that a marker 151 for identifying direction is provided at the jaw end or the gingival end of the central axis groove 150. In the drawings, the marker 151 is an arrow, and is recessed in the arc-shaped mating surface 120 and communicates with the central axis groove 150.

[0098] In combination with the above, it can be seen that the present application also discloses a combined orthodontic system, including multiple aesthetic fixed appliances in the above-mentioned technical solutions, dental arch wires inserted between each aesthetic fixed appliance, and a transparent invisible braces 300 for keeping the dental arch wires bound to or covering each aesthetic fixed appliance.

[0099] In the early stage of correction, the dental arch wire can be conveniently inserted through the archwire slot 200 to achieve rapid correction. In the later stage of correction, the suitable transparent invisible braces 300 can be adapted through the stop plane 140 or the overall shape of the main body 100, thereby improving the patient's treatment experience while taking into account the treatment effect.

[0100] Reference Attachment Figure 5 To the attached Figure 20 , the present application also discloses a variety of aesthetic fixed orthodontic appliances, including a body 100 and an archwire slot 200 passing through the body 100;

[0101] The body 100 is a one-piece structure, with one side being a bonding surface 110 for connecting to a tooth surface and the other side being a curved mating surface 120 for engaging other components. At least a portion of the archwire slot 200 is exposed on the curved mating surface 120. This means that the present application also discloses an open aesthetic fixed braces that can be used in conjunction with clear invisible braces.

[0102] From a structural perspective, the main body 100 has an arcuate mating surface 120 with relative mandibular lateral edges 121, gingival lateral edges 122, distal lateral edges 123, and mesial lateral edges 124. The mandibular lateral edges 121 and the gingival lateral edges 122 are arranged relative to each other and close to the bonding surface 110. The middle portion of the mandibular lateral edges 121 and the gingival lateral edges 122 is away from the bonding surface 110 to form a thickened portion 130. The archwire slot 200 is arranged in the thickened portion 130 and passes through the distal lateral edges 123 and the mesial lateral edges 124. In terms of the dimensional relationship between the side edges, the thickness of the mandibular lateral edge 121 is less than or close to the thickness of the gingival lateral edge 122. The thickness is specifically expressed as the height formed relative to the bonding surface 110. The advantage of the above arrangement is that it can ensure that the transparent invisible braces can be easily removed.

[0103] Reference Attachment Figure 1 , attached Figure 3 , attached Figure 12 , attached Figure 14 , attached Figure 19 And attached Figure 21In the embodiment shown, a cleaning groove 201 is provided in the middle position between the distal side edge 123 and the mesial side edge 124, and the cleaning groove 201 is connected to the archwire slot 200 from the arc-shaped mating surface 120. The cleaning groove 201 can facilitate the cleaning of the patient's oral hygiene during treatment in clinical practice, especially the cleaning inside the archwire slot 200; the setting of being connected to the archwire slot 200 allows the cleaning groove 201 to provide a certain operating space when threading the archwire. In the direction approaching the bonding surface 110, the size of the cleaning groove 201 gradually decreases and the inner surface transitions smoothly. In a particular embodiment, the ratio between the maximum cross-sectional area S1 of the cleaning groove 201 and the surface area S2 of the arc-shaped mating surface 120 ranges from 0.1 to 0.5. The opening of the archwire slot 200 is located on the arc-shaped mating surface 120. Furthermore, the opening of the archwire slot 200 is located at the thickened portion 130. Refer to the attached Figure 6 As shown, the archwire slot 200 has a trumpet-shaped archwire introduction opening. In a particular embodiment, the narrowest portion of the archwire slot 200 has an opening width W2. The distance L1 extending between the jaw-facing edge 121 and the gingival-facing edge 122 on the arcuate mating surface 120 is defined by the ratio of W2 to L1, and the ratio ranges from 0.1 to 0.5.

[0104] The present application also discloses a combined orthodontic system, comprising a plurality of aesthetic fixed appliances in the above technical solutions, dental arch wires passed between the aesthetic fixed appliances, and a transparent invisible orthodontic appliance 300 for binding or covering the dental arch wires on the aesthetic fixed appliances.

[0105] It's easy to understand that when the archwire slot 200 is open, components or structures are needed to maintain the force exerted on the archwire. At least a portion of the clear invisible aligner 300 extends into the archwire slot 200. In the accompanying drawings, the clear invisible aligner 300 forms a protrusion 301 through its own shape, thereby enhancing the effect on the archwire.

[0106] Reference Attachment Figure 9 To the attached Figure 20 , the present application also discloses an aesthetic fixed orthodontic appliance, comprising a body 100 and an archwire slot 200 passing through the body 100;

[0107] The body 100 is a one-piece structure, with one side being a bonding surface 110 for connecting to a tooth surface and the other side being a curved mating surface 120 for engaging a transparent invisible aligner 300. A restraining structure is provided on the curved mating surface 120, which is either protruding or recessed relative to the body 100 and includes at least two intersecting positioning planes. This means that this application also discloses a single-piece, aesthetic fixed aligner.

[0108] By using the constraint structure and the positioning plane, the positioning effect of the aesthetic fixed appliance on the attachment can be better achieved. In terms of specific implementation, the constraint structure can have various forms.

[0109] Reference Attachment Figure 9 To the attached Figure 11 In the embodiment shown, the constraint structure includes a plurality of positioning posts 401 disposed on the arc-shaped mating surface 120, and the positioning posts 401 are raised compared to the arc-shaped mating surface 120. Figure 11 In the figure, the end of the positioning post 401 away from the arcuate mating surface 120 radially expands to form an enlarged portion 402. In terms of overall layout, the positioning posts 401 are arranged in pairs, with at least two groups of positioning posts 401 located on either side of the archwire slot 200. Accordingly, when the transparent invisible aligner 300 or a transparent invisible aligner is mated with multiple positioning posts 401, a connected constrained space 403 can be formed, as shown in the accompanying drawings, to improve the mating effect while reducing the difficulty of assembly.

[0110] Attachment Figure 12 and attached Figure 13 In the embodiment shown in FIG, it can be understood that a plurality of positioning posts 401 are connected to each other to form a positioning bar 410 and extend away from each other.

[0111] Reference Attachment Figure 17 To the attached Figure 20 In the illustrated embodiment, the constraint structure includes a plurality of constraint holes 404 formed on the body 100, wherein the opening direction of the constraint holes 404 is parallel to the extension direction of the archwire slot 200.

The cross-sectional shape of the constraint holes 404 is non-circular. Accordingly, in the process of cooperating with the plurality of constraint holes 404, the transparent invisible aligner 300 can form a plurality of claws 405 as shown in the accompanying drawings, which are wrapped around both sides of the body 100 while cooperating with the constraint holes 404 to improve the positioning effect.

[0112] Reference Attachment Figure 14 To the attached Figure 16In the illustrated embodiment, the constraint structure includes a plurality of constraint grooves 406 provided on the main body 100, and the opening direction of the constraint grooves 406 intersects with the extension direction of the archwire slot 200.

Each constraint groove 406 includes two auxiliary grooves 407 aligned with each other in the extension direction, and a stopper 408 is provided between the two auxiliary grooves 407. The stopper 408 can further improve the constraint capacity in multiple dimensions. Accordingly, in the process of cooperating with the plurality of constraint grooves 406, the transparent invisible braces 300 can form a plurality of adaptive bends 409 as shown in the accompanying drawings to achieve a connection effect with the main body 100.

[0113] The present application also discloses a combined orthodontic system, comprising a plurality of aesthetic fixed appliances in the above-mentioned technical solutions, dental arch wires passed between the aesthetic fixed appliances, and a transparent invisible appliance 300 for retaining the dental arch wire in the archwire slot 200, wherein the transparent invisible appliance 300 is covered on each aesthetic fixed appliance.

[0114] In one embodiment, at least a portion of the transparent invisible aligner 300 cooperates with the constraint structure. The specific cooperation method can be found above and will not be described in detail here.

[0115] Reference Attachment Figure 21 To the attached Figure 24 , the present application also discloses an aesthetic fixed orthodontic appliance, comprising a body 100 and an archwire slot 200 passing through the body 100;

[0116] The main body 100 is a one-piece structure, with one side being a bonding surface 110 for connecting to the tooth surface and the other side being a curved mating surface 120 for engaging other components. The curved mating surface 120 has a jaw-facing edge 121 and a gingival edge 122, with the jaw-facing edge 121 being adjacent to the bonding surface 110. The archwire slot 200 is disposed between the gingival edge 122 and the bonding surface, with its opening aligned with the bonding surface 110. This means that the present application also discloses a laterally slotted aesthetic fixed appliance.

[0117] In the specific configuration, the jaw side edge 121 first extends away from the archwire slot 200 to form a first positioning edge 1211 and then extends toward the archwire slot 200 to cooperate with the bonding surface 110. The gingival side edge 122 protrudes from the side edge of the bonding surface 110 to form a second positioning edge 1221. Figure 22 The archwire slot 200 has an opening depth D4 of greater than or equal to 0.7 mm, and an opening width W4 of the archwire slot 200 of greater than or equal to 0.5 mm. In a particular embodiment, the ratio of the opening depth D4 of the archwire slot 200 to the width W3 of the bonding surface 110 in the direction of the opening of the archwire slot 200 is 0.3 to 0.8.

[0118] The present application also discloses a combined orthodontic system, comprising a plurality of aesthetic fixed appliances in the above-mentioned technical solutions, dental arch wires passed between the aesthetic fixed appliances, and a transparent invisible appliance 300 for retaining the dental arch wire in the archwire slot 200, wherein the transparent invisible appliance 300 is covered on each aesthetic fixed appliance.

[0119] In terms of the specific mating relationship, the transparent invisible braces 300 wraps around the curved mating surface 120 from the jaw-facing side edge 121 and then closes the archwire slot 200 via the gingival side edge 122. The jaw-facing side edge 121 first extends away from the archwire slot 200 to form a first positioning edge 1211, and then extends toward the archwire slot 200 to mate with the bonding surface 110. The transparent invisible braces 300 is provided with a first edging 302 that mates with the first positioning edge 1211. The gingival side edge 122 protrudes from the side edge of the bonding surface 110 to form a second positioning edge 1221. The transparent invisible braces 300 is provided with a second edging 303 that mates with the second positioning edge 1221. The side of the transparent invisible braces 300 away from the first edging 302 is also provided with a guide bevel 304. The guide bevel 304 is used to drive the deformation of the transparent invisible braces 300 to achieve its own wrapping of the aesthetic fixed braces. The transparent invisible braces 300 is provided with an array of reinforcing ribs 305 on the part that closes the archwire slot 200. The provision of the reinforcing ribs 305 can avoid the problem of reduced archwire restraint due to lateral opening.

[0120] Reference Attachment Figure 25 To the attached Figure 28 As shown, the present application also discloses an aesthetic fixed appliance. Compared with other embodiments, the characteristic of this embodiment is that the body 100 of the aesthetic fixed appliance adopts a double-layer structure, wherein the volume of the lower part used to form the bonding surface is larger than the volume of the upper part used to form the arc-shaped matching surface, and both the upper and lower parts can be provided with a stop plane 140 for achieving position limiting. In the technical solution shown in the accompanying drawings, the archwire slot 200 is located in the upper part, and at least a part of the archwire 500 passes through the upper part of the lower part after passing through the archwire slot 200; the transparent invisible appliance 300 covers the upper part and a part of it covers the upper surface of the lower part. The specific setting of the upper part can be referred to the attached Figure 5 To the attached Figure 8b Description of aesthetic fixed appliances.
