Figure 3 is a schematic structural diagram of the displacement angle adjustment component provided by the embodiments of the present application.

[0047] As Figures 1 to 3As shown in the figure, an embodiment of the present application provides an adjustable oral appliance, including: an upper alveolar body 1, a lower alveolar body 2 and an intermediate connecting body 3 that constitute the main body of the appliance. Among them, the root side of the upper alveolar body 1 has a first connecting structure 4, and the root side of the lower alveolar body 2 has a second connecting structure 5. The intermediate connecting body 3 has a shape that is at least adapted to the upper alveolar body 1 or the lower alveolar body 2. The intermediate connecting body 3 includes docking structures 6 provided on the upper end surface and the lower end surface of the intermediate connecting body 3. The first connecting structure 4 and the second connecting structure 5 are respectively detachably connected to the docking structure 6, so that the upper alveolar body 1 and the lower alveolar body 2 are respectively detachably connected to the intermediate connecting body 3.

[0048] In this embodiment, the intermediate connecting body 3 is arranged as a first U-shaped structure, and the first U-shaped structure is adapted to the U-shaped structure of the upper alveolar body 1 or the lower alveolar body 2.

[0049] Specifically, in this embodiment, the first connecting structure 4 includes a first positioning rivet groove, and the second connecting structure 5 includes a second positioning rivet groove. Correspondingly, the docking structure 6 includes rivets, and the rivets can be respectively riveted in the first positioning rivet groove and the second positioning rivet groove. In one example, the first positioning rivet grooves can be distributed at multiple positions on the root side of the upper alveolar body 1, and are preferably arranged at the front part and the two rear end parts of the upper alveolar body 1 to improve the connection stability during connection. Correspondingly, the second positioning rivet grooves can be distributed at multiple positions on the root side of the lower alveolar body 2, and are preferably arranged at the front part and the two rear end parts of the lower alveolar body 2 to improve the connection stability during connection.

[0050] In one example, multiple first positioning rivet grooves or second positioning rivet grooves can be provided at the same part, that is, the first positioning rivet grooves located at the same part form a first positioning rivet groove group, and the second positioning rivet grooves located at the same part form a second positioning rivet groove group. The cross-sections of the first positioning rivet groove group and the second positioning rivet groove group can be arranged in various shapes. Correspondingly, multiple rivets corresponding to the first positioning rivet groove group or the second positioning rivet groove group located at the same part are provided, and each rivet can be riveted in each first positioning rivet groove.

[0051] The first connecting structure 4 and the second connecting structure 5 are respectively detachably connected to the docking structure 6, so that the upper alveolar body 1 and the lower alveolar body 2 are respectively detachably connected to the intermediate connecting body 3. That is, when it is necessary to replace the upper alveolar body 1 or the lower alveolar body 2, the first connecting structure 4 or the second connecting structure 5 can be disassembled and separated from the docking structure 6, and the replacement of the upper alveolar body 1 or the lower alveolar body 2 can be realized. Thus, it is no longer necessary to replace the entire appliance when only one of the upper alveolar body 1 or the lower alveolar body 2 needs to be replaced, thereby reducing the cost of using the appliance.

[0052] Furthermore, in order to meet the orthodontic forms corresponding to the upper alveolar body 1 or the lower alveolar body 2 at different time periods, in addition to timely replacing the upper alveolar body 1 or the lower alveolar body 2, the displacement angle of the upper alveolar body 1 or the lower alveolar body 2 relative to the middle connecting body 3 can also be adjusted to adjust the displacement angle of the upper alveolar body 1 relative to the upper teeth and the displacement angle of the lower alveolar body 2 relative to the lower teeth.

[0053] Specifically, in this embodiment, it further includes a displacement angle adjustment component 7. For correspondingly installing the displacement angle adjustment component 7, the middle connecting body 3 includes an upper connecting body 31 and a lower connecting body 32, and the upper connecting body 31 and the lower connecting body 32 respectively have a first U-shaped structure. The docking structure 6 is arranged on the upper end surface of the upper connecting body 31 and the lower end surface of the lower connecting body 32, so that the upper connecting body 31 can be detachably connected to the upper alveolar body 1, and the lower connecting body 32 can be detachably connected to the lower alveolar body 2. Among them, the displacement angle adjustment component 7 is arranged between the upper connecting body 31 and the lower connecting body 32, and is used to adjust the relative displacement angle between the upper connecting body 31 and the lower connecting body 32 through the displacement angle adjustment component 7, so as to adjust the displacement angle of the upper alveolar body 1 or the lower alveolar body 2 relative to the middle connecting body 3, thereby adjusting the displacement angle of the upper alveolar body 1 relative to the upper teeth and the displacement angle of the lower alveolar body 2 relative to the lower teeth.

[0054] Specifically, the displacement angle adjustment component 7 includes a positioning support plate 71, a set of positioning slots 72, a steering bearing 73, a first connecting rotating rod 74, and a second connecting rotating rod 75. Among them, the positioning support plate 71 is arranged horizontally between the upper connecting body 31 and the lower connecting body 32. In an example, the positioning support plate 71 is arranged in a flat plate shape and has a second U-shaped structure, which is adapted to the U-shaped structure of the upper alveolar body 1 or the lower alveolar body 2; alternatively, the second U-shaped structure can correspond to a part of the first U-shaped structure, that is, the second U-shaped structure can correspond to the middle part of the first U-shaped structure. The set of positioning slots 72 are respectively arranged on the upper end surface and the lower end surface of the positioning support plate 71, and each set of positioning slots 72 includes a plurality of positioning slots 72. The plurality of positioning slots 72 on each end surface are arranged side by side along the width direction of the positioning support plate 71. The upper end surface of the positioning support plate 71 faces the upper connecting body 31, and the width direction of the positioning support plate 71 is the width direction between the retaining plates of the upper alveolar body 1 or the lower alveolar body 2. The steering bearing 73 can be clamped in any one of the positioning slots 72. The first end of the first connecting rotating rod 74 is rotatably connected to the steering bearing 73 located on the upper end surface of the positioning support plate 71, so that the first connecting rotating rod 74 can adjust its position in the width direction; the second end of the first connecting rotating rod 74 is fixedly connected to the upper connecting body 31, and then drives the upper connecting body 31 to adjust its position in the width direction. By rotating the first connecting rotating rod 74 relative to the steering bearing 73 on the upper end surface of the positioning support plate 71, the relative rotation of the upper connecting body 31 driving the upper alveolar body 1 is adjusted. The first end of the second connecting rotating rod 75 is rotatably connected to the steering bearing 73 located on the lower end surface of the positioning support plate 71, so that the second connecting rotating rod 75 can adjust its position in the width direction; the second end of the second connecting rotating rod 75 is fixedly connected to the lower connecting body 32, and then drives the lower connecting body 32 to adjust its position in the width direction. By rotating the second connecting rotating rod 75 relative to the steering bearing 73 on the lower end surface of the positioning support plate 71, the relative rotation of the lower connecting body 32 driving the lower alveolar body 2 is adjusted.

[0055] Further, in order to improve the rotation accuracy of the first connecting rotating rod 74 and the second connecting rotating rod 75, the displacement angle adjustment component 7 further includes a first displacement angle adjustment gear 76 and a second displacement angle adjustment gear 77. Among them, the first displacement angle adjustment gear 76 is arranged on the first connecting rotating rod 74, and the rotation of the first connecting rotating rod 74 is driven by adjusting the tooth degree of the first displacement angle adjustment gear 76. Among them, each adjacent two adjustment teeth in the first displacement angle adjustment gear 76 are provided with corresponding angles. The second displacement angle adjustment gear 77 is arranged on the second connecting rotating rod 75, and the rotation of the second connecting rotating rod 75 is driven by adjusting the tooth degree of the second displacement angle adjustment gear 77. Among them, each adjacent two adjustment teeth in the second displacement angle adjustment gear 77 are provided with corresponding angles.

[0056] In this embodiment, the displacement angle adjustment assembly 7 can be arranged at a plurality of relative positions between the upper connecting body 31 and the lower connecting body 32. In this embodiment, it is preferably arranged between the middle positions of the upper connecting body 31 and the lower connecting body 32 respectively.

[0057] In this embodiment, in order to improve the connection stability between the upper connecting body 31 and the lower connecting body 32, a plurality of connectable connection support structures 8 are provided between the lower end surface of the upper connecting body 31 and the upper end surface of the lower connecting body 32, and the connection between the upper connecting body 31 and the lower connecting body 32 is realized through the plurality of connection support structures 8. Among them, in one example, the connection support structure 8 at least includes one of the following structures: a card slot and a convex structure, a stud and a threaded groove structure, or a rivet and a rivet groove structure.

[0058] In this embodiment, in order to improve the applicability and aesthetics of the upper alveolar body 1, the lower alveolar body 2 and the intermediate connecting body 3 that constitute the orthodontic appliance main body, and to prevent substances in the oral cavity from entering between the upper alveolar body 1, the lower alveolar body 2 and the intermediate connecting body 3, a first accommodating structure (not shown) and a second accommodating structure (not shown) are further included. Among them, the first accommodating structure is arranged at the root-side edge of the upper alveolar body 1, and the second accommodating structure is arranged at the root-side edge of the lower alveolar body 2. The first connecting structure 4 is arranged in the first accommodating structure, and the second connecting structure 5 is arranged in the second accommodating structure. When the first connecting structure 4 and the second connecting structure 5 are respectively connected to the docking structure 6, the first accommodating structure and the second accommodating structure are buckled, so that the upper alveolar body 1 and the lower alveolar body 2 are spliced, and the intermediate connecting body 3 is encapsulated in the accommodating space formed by the buckling of the first accommodating structure and the second accommodating structure. The arrangement of the first accommodating structure and the second accommodating structure not only realizes the splicing of the upper alveolar body 1 and the lower alveolar body 2, so that the external contour of the formed orthodontic appliance main body forms a complete structure. It can also provide an accommodating space for the intermediate connecting body 3. In addition, through the first accommodating structure and the second accommodating structure, the upper alveolar body 1 and the lower alveolar body 2 are spliced and buckled, and the first connecting structure 4 and the second connecting structure 5 are respectively connected to the docking structure 6 of the intermediate connecting body 3, so that the acting forces between the upper alveolar body 1, the lower alveolar body 2 and the intermediate connecting body 3 act on each other, thereby enhancing the connection strength of the orthodontic appliance main body formed by the upper alveolar body 1, the lower alveolar body 2 and the intermediate connecting body 3.

[0059] Further, in one example, the first accommodation structure includes a first accommodation groove, a first engageable groove, and a first engaging protrusion. The first accommodation groove is provided on the root side of the upper alveolar body 1. The first engageable groove is provided on the first edge of the first accommodation groove. The first engaging protrusion is provided on the second edge of the first accommodation groove. The first edge and the second edge are opposite to each other. The second accommodation structure includes a second accommodation groove, a second engageable groove, and a second engaging protrusion. The second accommodation groove is provided on the root side of the lower alveolar body 2. The second engageable groove is provided on the first edge of the second accommodation groove. The second engaging protrusion is provided on the second edge of the second accommodation groove. The first edge and the second edge are opposite to each other. When the first connection structure 4 and the second connection structure 5 are respectively connected to the docking structure 6, the first engageable groove and the second engaging protrusion are engaged, and the first engaging protrusion and the second engageable groove are engaged. The first accommodation groove and the second accommodation groove form an accommodation space.

[0060] An embodiment of the present application provides an adjustable oral appliance, including: an upper alveolar body 1, a lower alveolar body 2, and an intermediate connecting body 3 that constitute the main body of the appliance. Among them, the root side of the upper alveolar body 1 has a first connection structure 4, and the root side of the lower alveolar body 2 has a second connection structure 5. The intermediate connecting body 3 has at least a shape adapted to the upper alveolar body 1 or the lower alveolar body 2. The intermediate connecting body 3 includes a docking structure 6 provided on the upper end face and the lower end face of the intermediate connecting body 3. The first connection structure 4 and the second connection structure 5 are respectively detachably connected to the docking structure 6, so that the upper alveolar body 1 and the lower alveolar body 2 are respectively detachably connected to the intermediate connecting body 3.

[0061] In this embodiment, the first connection structure 4 and the second connection structure 5 are respectively detachably connected to the docking structure 6, so that the upper alveolar body 1 and the lower alveolar body 2 are respectively detachably connected to the intermediate connecting body 3. That is, when it is necessary to replace the upper alveolar body 1 or the lower alveolar body 2, the first connection structure 4 or the second connection structure 5 can be detached from the docking structure 6, and the replacement of the upper alveolar body 1 or the lower alveolar body 2 can be realized. Thus, it is no longer necessary to replace the entire appliance when only one groove of the upper alveolar body 1 or the lower alveolar body 2 needs to be replaced, thereby reducing the cost of using the appliance. Based on the relatively low cost of the appliance components, the corresponding components can be replaced in a timely manner, and then the orthodontic requirements can be met and the orthodontic effect can be improved.

[0062] In addition, the relative displacement angle between the upper connecting body 31 and the lower connecting body 32 is adjusted by the displacement angle adjustment assembly 7 to adjust the displacement angle of the upper alveolar body 1 or the lower alveolar body 2 relative to the intermediate connecting body 3, so as to adjust the displacement angle of the upper alveolar body 1 relative to the upper teeth and the displacement angle of the lower alveolar body 2 relative to the lower teeth, thereby meeting the orthodontic requirements and improving the orthodontic effect.

Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present application, and all such changes and modifications are within the scope of protection of the present application.
