[0043] In the related art, during the orthodontic treatment process, as time goes by, the dental deformity is gradually corrected, and some parts of the original orthodontic appliance cannot provide the corresponding orthodontic force. Moreover, the existing orthodontic appliances need to attach to the teeth through complex mechanical structures to rapidly expand the dental arch, so the orthodontic effect is limited to a certain extent, resulting in poor orthodontic effect on the oral cavity.

[0044] Therefore, the present application provides an adjustable dental arch expanding orthodontic appliance, including: an upper dental alveolar body, a lower dental alveolar body, and adjusting components respectively arranged on the upper dental alveolar body and the lower dental alveolar body; the adjusting components include an adjusting part, a plurality of positioning parts, and a connecting part. Among them, the positioning part is arranged at a first designated position of the upper dental alveolar body or the lower dental alveolar body, the adjusting part is arranged at a second designated position of the upper dental alveolar body or the lower dental alveolar body, the adjusting part has a preset adjusting angle relative to each positioning part, and the connecting part connects the adjusting part and each positioning part, and drives the connecting part to pull the positioning part according to the preset adjusting angle by rotating the adjusting part to adjust the dental arch expanding angle of the upper dental alveolar body and the lower dental alveolar body.

[0046] Next, the adjustable dental arch expanding orthodontic appliance provided by the present application, hereinafter simply referred to as the orthodontic appliance, will be described in conjunction with the drawings.

[0047] Figure 1 It is a schematic structural diagram of an adjustable arch-expanding oral appliance provided by an embodiment of the present application. Figure 2 is Figure 1 A schematic structural diagram of an adjustable arch-expanding oral appliance presented by the horizontal cross-section of Figure 3 is Figure 1 Another schematic structural diagram of an adjustable arch-expanding oral appliance presented by the horizontal cross-section of Figure 4 is Figure 1 Still another schematic structural diagram of an adjustable arch-expanding oral appliance presented by the horizontal cross-section of Figure 5 It is a schematic structural diagram of the connection between a shaft rod and an adjusting rotating shaft provided by an embodiment of the present application.

[0048] In this embodiment, the adjustable arch-expanding oral appliance includes: an upper alveolar body 10, a lower alveolar body 20, and an adjusting assembly 1 respectively arranged on the upper alveolar body 10 and the lower alveolar body 20. Among them, the adjusting assembly 1 includes an adjusting part 2, a plurality of positioning parts 3, and a connecting part 4. The positioning part 3 is arranged at a first designated position of the upper alveolar body 10 or the lower alveolar body 20. The first designated position of the upper alveolar body 10 or the lower alveolar body 20 refers to any position of the groove bodies on both sides of the upper alveolar body 10 or the lower alveolar body 20. The adjusting part 2 is arranged at a second designated position of the upper alveolar body 10 or the lower alveolar body 20. The second designated position of the upper alveolar body 10 or the lower alveolar body 20 refers to the front position of the upper alveolar body 10 or the lower alveolar body 20 respectively. The adjusting part 2 has a preset adjusting angle relative to each positioning part 3. The connecting part 4 connects the adjusting part 2 and each positioning part 3, and drives the connecting part 4 to pull the positioning part 3 according to the preset adjusting angle by rotating the adjusting part 2 so as to adjust the arch-expanding angle of the upper alveolar body 10 and the lower alveolar body 20.

[0049] Further, in this embodiment, the upper alveolar body 10 includes a lower joint portion, which is an end face portion of the end away from the groove body of the upper alveolar body 10. The lower alveolar body 20 includes an upper joint portion, which is an end face portion of the end away from the groove body of the lower alveolar body 20. The lower joint portion and the upper joint portion face each other, and the connection of the lower joint portion and the upper joint portion can form an adjustment space. Among them, in one example, the upper alveolar body 10 and the lower alveolar body 20 are connected by a connection component (not shown). The connection component includes a hinge structure and a magnetic attraction component. The hinge structure is arranged at the front position of the upper alveolar body 10 and the lower alveolar body 20 to connect the upper alveolar body 10 and the lower alveolar body 20. The upper alveolar body 10 and the lower alveolar body 20 can be relatively expanded through the hinge structure. Specifically, the hinge structure is arranged at the front position of the lower joint portion of the upper alveolar body 10 and the front position of the upper joint portion of the lower alveolar body 20. The magnetic attraction component is arranged between the upper alveolar body 10 and the lower alveolar body 20 to attract the upper alveolar body 10 and the lower alveolar body 20 through magnetic attraction. Specifically, the magnetic attraction component includes an N-pole member and an S-pole member. Among them, the N-pole member is arranged on the end face of the lower joint portion of the upper alveolar body 10 away from the groove body, and the S-pole member is arranged on the end face of the upper joint portion of the lower alveolar body 20 away from the groove body. The N-pole member and the S-pole member face each other and attract each other to attract the upper alveolar body 10 and the lower alveolar body 20. It should be noted that the magnetic attraction component is set as a detachable structure, that is, when it is necessary to adjust the expansion angle of the upper alveolar body 10 and the lower alveolar body 20, the magnetic attraction component can be disassembled. Or, the adjustment force of the adjustment component 1 is much greater than the magnetic attraction force of the magnetic attraction component, and then the expansion angle of the upper alveolar body 10 and the lower alveolar body 20 can be adjusted without disassembling the magnetic attraction component.

[0050] In another example, the lower joint portion includes a first accommodation groove and a first snap-in groove arranged on the edge of the first accommodation groove. The upper joint portion includes a second accommodation groove and a second snap-in groove arranged on the edge of the second accommodation groove. The first snap-in groove and the second snap-in groove are snap-fitted, and the first accommodation groove and the second accommodation groove form an adjustment space. That is to say, the upper alveolar body 10 and the lower alveolar body 20 in this embodiment can be independent and are not integrally formed structures. The upper alveolar body 10 and the lower alveolar body 20 can be connected through the lower joint portion and the upper joint portion to form the main body of the orthodontic appliance. It should be noted that the snap-fitting of the first snap-in groove and the second snap-in groove does not limit the freedom degree of the upper alveolar body 10 and the lower alveolar body 20 in the horizontal direction, and thus does not affect the adjustment component 1 to adjust the expansion angle of the upper alveolar body 10 and the lower alveolar body 20.

[0051] The positioning parts 3 are respectively arranged at the first designated positions of the lower joint part and the upper joint part. Among them, in combination with the specific structure of the lower joint part and the upper joint part, the first designated position of the lower joint part refers to any position on the groove surfaces on both sides of the first accommodating groove, and the first designated position of the upper joint part refers to any position on the groove surfaces on both sides of the second accommodating groove. The adjusting parts 2 are respectively arranged at the second designated positions of the lower joint part and the upper joint part. Among them, in combination with the specific structure of the lower joint part and the upper joint part, the second designated position of the lower joint part refers to the front position of the first accommodating groove, and the second designated position of the upper joint part refers to the front position of the second accommodating groove. The connecting part 4 is placed in the adjusting space and connects the adjusting part 2 and each positioning part 3. The connecting part 4 can swing in the adjusting space according to a preset adjusting angle.

[0052] In this embodiment, preferably, there is one adjusting part 2. Among them, the adjusting part 2 includes a fixing groove 21, a shaft rod 22, an adjusting rotating shaft 23 and a positioning assembly 25. Specifically, the fixing grooves 21 are respectively arranged at the front positions of the upper joint part and the lower joint part, and the notch direction of the fixing groove 21 is arranged in the vertical direction. The shape of the fixing groove 21 can be set according to requirements. The fixing groove 21 can be recessed in the horizontal end surfaces of the fronts of the upper joint part and the lower joint part respectively. The shaft rod 22 is connected in the fixing groove 21 along the vertical direction. In one example, the shaft rod 22 can be fixedly arranged in the fixing groove 21. In another example, the shaft rod 22 can be detachably connected to the fixing groove 21 through a connecting structure. Among them, the connecting structure includes a spline and a spline groove. The spline groove is arranged in the fixing groove 21, and the spline is arranged at one end of the shaft rod 22. The spline and the spline groove are inserted to detachably connect the shaft rod 22 to the fixing groove 21. The adjusting rotating shaft 23 is sleeved on the shaft rod 22 and can rotate around the shaft rod 22. Specifically, in one example, a bearing 26 is arranged between the adjusting rotating shaft 23 and the shaft rod 22, and the adjusting rotating shaft 23 rotates relative to the shaft rod 22 through the bearing 26. A connecting ring groove is arranged on the adjusting rotating shaft 23.

[0053] The positioning component 25 is disposed between the adjusting rotating shaft 23 and the upper and lower joint parts, and is used to position the adjusting rotating shaft 23 after the adjusting rotating shaft 23 rotates for adjustment. Specifically, in one example, the positioning component 25 includes a positioning protrusion, a spring, and a plurality of positioning and limiting grooves. Among them, the plurality of positioning and limiting grooves are respectively arranged in an annular shape on the end faces of the upper and lower joint parts relative to the adjusting rotating shaft 23. One end of the spring is fixed in the accommodating groove on the radial edge of the adjusting rotating shaft 23, and the other end of the spring is connected to the positioning protrusion. The positioning protrusion has a morphological structure adapted to the positioning and limiting groove. The positioning protrusion is inserted into the corresponding positioning and limiting groove by the elastic force of the spring. In one example, the positioning component 25 further includes a handle and an opening groove. The opening groove is arranged on the groove wall of the accommodating groove. The handle is connected to the positioning protrusion and can be slidably connected in the opening groove and protrudes out of the notch of the opening groove. During operation, when the adjusting rotating shaft 23 needs to rotate, the handle is toggled to drive the positioning protrusion to disengage from the positioning and limiting groove. The adjusting rotating shaft 23 rotates to drive the positioning protrusion to rotate synchronously. After the adjusting rotating shaft 23 rotates a specified angle, the handle is released so that the positioning protrusion can be inserted into the current positioning and limiting groove, thereby realizing the fixation of the adjusting rotating shaft 23.

[0054] In another example, the adjusting part 2 includes a fixing groove 21, a positioning bearing 27, an adjusting rotating shaft 23, and a positioning component ( Figure 4 not shown), wherein the fixing grooves 21 are respectively arranged at the front positions of the upper and lower joint parts, and the notch direction of the fixing groove 21 is set along the horizontal direction. The shape of the fixing groove 21 can be set according to requirements. The fixing groove 21 can be recessed in the vertical end faces of the fronts of the upper and lower joint parts respectively. The positioning bearing 27 is installed in the fixing groove 21, and the axial direction of the positioning bearing 27 is distributed along the horizontal direction. The adjusting rotating shaft 23 is sleeved and connected to the positioning bearing 27 and rotates synchronously with the positioning bearing 27. A connecting ring groove is provided on the adjusting rotating shaft 23.

[0055] The positioning component is disposed between the adjusting rotating shaft 23 and the upper and lower joint parts, and is used to position the adjusting rotating shaft 23 after the adjusting rotating shaft 23 rotates for adjustment. Specifically, in one example, the positioning component includes a receiving groove, a positioning protrusion, a spring, and a plurality of positioning and limiting grooves, wherein the plurality of positioning and limiting grooves are arranged in a ring along the circumferential end surface of the adjusting rotating shaft 23. The receiving groove is recessed relative to the positioning and limiting grooves on the horizontal end surfaces of the front parts of the upper and lower joint parts respectively. One end of the spring is fixed in the receiving groove, and the other end of the spring is connected to the positioning protrusion. The positioning protrusion has a morphological structure adapted to the positioning and limiting groove. The positioning protrusion is inserted into the corresponding positioning and limiting groove by the elastic force of the spring. In one example, the positioning component 25 further includes a handle, and the handle is connected to the positioning protrusion. During operation, when the adjusting rotating shaft 23 needs to rotate, the handle is toggled to drive the positioning protrusion to disengage from the positioning and limiting groove. After the adjusting rotating shaft 23 rotates and reaches a specified angle, the handle is released so that the positioning protrusion can be inserted into the current positioning and limiting groove, thereby realizing the fixation of the adjusting rotating shaft 23.

[0056] Furthermore, in one example, the shaft rod 22 includes multiple sub-shaft rods 22 of segments, and correspondingly, the adjusting rotating shaft 23 includes multiple sub-adjusting rotating shafts 24 of segments. Each sub-adjusting rotating shaft 24 is correspondingly sleeved on each sub-shaft rod 22 to rotate on each sub-shaft rod 22. Specifically, the sub-adjusting rotating shafts 24 are distributed in the vertical direction, and a bearing 26 is provided between each sub-shaft rod 22 and each sub-adjusting rotating shaft 24. The sub-adjusting rotating shaft 24 rotates on the sub-shaft rod 22 through the bearing 26. A connecting ring groove is provided on the sub-adjusting rotating shaft 24. In another example, multiple sub-adjusting rotating shafts 24 are distributed in the vertical direction on one shaft rod 22. By setting multiple sub-adjusting rotating shafts 24, different rotation angles can be increased, and the connection quantity of the connecting part 4 can be increased, so that there are more adjustment methods for the connecting part 4 to pull the positioning part 3 according to a preset adjustment angle to adjust the expansion angles of the upper alveolar body 10 and the lower alveolar body 20.

[0057] In addition, when the adjusting rotating shaft 23 includes multiple sub-adjusting rotating shafts 24 of segments, the positioning component 25 is disposed between the sub-adjusting rotating shaft 24 close to the upper and lower joint parts and the upper and lower joint parts.

[0058] In this embodiment, the positioning part 3 includes a positioning groove and a positioning member, wherein the positioning groove is respectively arranged at the first designated position of the lower joint part and the first designated position of the upper joint part, and the first designated position is multiple. The positioning member is fixed in the positioning groove, and a connecting hole is arranged on the positioning member. The connecting part 4 includes a connecting rope. The first end of the connecting rope is wound around the connecting ring groove of the adjusting rotating shaft 23, and the second end of the connecting rope is connected to the connecting hole. The number of connecting ropes includes at least one. In one example, the positioning part 3 is set as a slidable positioning part 3, that is, the positioning part 3 is arranged at the first designated position of the lower joint part and the first designated position of the upper joint part through a sliding positioning assembly. Among them, the sliding positioning assembly includes a slide rail and a positioning connection assembly, wherein the positioning connection assembly includes a card slot and a card body, the card slot is arranged along both sides of the slide rail, and the card body is arranged on the positioning part 3. The positioning part 3 is slidably connected to the slide rail, and when sliding to the designated first designated position, the card body is connected to the card slot through the card body to realize the positioning of the positioning part 3.

[0059] In this embodiment, when it is necessary to adjust the expansion angle of the upper alveolar body 10 and the lower alveolar body 20, the adjustment rotating shaft 23 is rotated so that the adjustment rotating shaft 23 drives the first end of the connecting rope to be wound, and then the connecting rope is directly pulled, and the positioning part 3 is pulled according to the preset adjustment angle to adjust the expansion angle of the upper alveolar body 10 and the lower alveolar body 20.

[0060] In this embodiment, in order to increase and change the direction of the adjustment force (pulling force) of the connecting portion 4, an adjustment force adjusting member 5 is further provided, and the adjustment force adjusting member 5 is arranged between the adjusting portion 2 and the positioning portion 3, and abuts against the connecting portion 4 to adjust the direction of the adjustment force of the connecting portion 4. Specifically, in one example, the adjustment force adjusting member 5 includes a steering shaft or a roller, and taking the steering shaft as an example, the steering shaft can rotate on the end faces of the upper joint portion and the lower joint portion, and the connecting rope is supported and wound around the circumferential end face of the steering shaft to change the direction of the adjustment force (pulling force) when the connecting rope is directly connected to the adjusting portion 2 and the positioning portion 3.

[0061] In one example, the regulating force adjusting member 5 is configured as a movable positioning structure. In one example, a connecting hole may be provided in the middle of the regulating force adjusting member 5, and the connecting rope may pass through the connecting hole. The setting of the connecting hole may improve the stability of the connection between the connecting rope and the regulating force adjusting member 5.
