Description

Technical Field

[0001] The utility model relates to the technical field of traction caps for orthodontic appliances, in particular to a traction cap for an invisible orthodontic appliance without brackets. Background Art

[0002] At present, in order to treat high-angle facial developmental abnormalities, reduce the mandibular angle, and control vertical development, an extraoral bow is usually used to perform high-position traction on the maxilla, so that the maxilla moves upward and grows, thereby achieving the purpose of controlling vertical development; or correction is performed through invisible braces to flatten the mandibular curve, reduce the steepness of the mandibular curve, rotate the mandible counterclockwise, and control vertical development.

[0003] For example, the patent with announcement number CN212415943U discloses a vertically controlled double-ply appliance. Although this vertically controlled double-ply appliance utilizes a head cap to vertically pull the anterior teeth area and to intrude and control the vertical growth of the anterior teeth, for patients with vertically growing mandibular retrusion, it is a better choice to establish occlusion by guiding the mandible forward while controlling the vertical growth of the maxillary anterior teeth; however, when this vertically controlled double-ply appliance is actually used, the positions of the left J hook and the right J hook on the head cap cannot be adjusted. When the patient wears the head cap on his head, the left J hook and the right J hook respectively hook the corresponding pull ring to pull the maxillary anterior teeth, and the positions of the left J hook and the right J hook may be located at the ears, resulting in the left J hook and the right J hook causing strangulation to the ears when pulling the maxillary anterior teeth for a long time, so it needs to be improved.

[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0029] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0030] like Figure 1As shown, a traction cap for a bracketless invisible brace appliance in this embodiment includes a traction cap body 100 and an appliance body 110, and arch wires 120 arranged on both sides of the appliance body 110. A mounting ring 130 is provided on the lower side surface of the traction cap body 100, and a relative mounting frame 140 is provided on the side wall of the mounting ring 130 along the circumference of the mounting ring 130. The mounting frame 140 is provided with a traction mechanism for driving the arch wire 120 to pull the appliance body 110; the traction mechanism includes a sliding plate 150 which is slidable and is provided on the mounting frame 140, and a positioning component for positioning the sliding of the sliding plate 150 is provided on the sliding plate 150, and a horizontal plate 500 is provided on the lower end surface of the sliding plate 150, and a connecting component for connecting the arch wire 120 is provided on the horizontal plate 500.

[0031] In this embodiment, the traction cap body 100 is worn on the patient's head, the appliance body 110 is occlusally sleeved on the patient's teeth, and the arch wires 120 on both sides of the appliance body 110 are extended out of the patient's oral cavity. At this time, by connecting the arch wire 120 to the traction mechanism, the traction cap body 100 can pull the arch wire 120 through the traction mechanism, and the appliance body 110 is pulled by the arch wire 120, thereby achieving the traction and correction of the teeth by the appliance body 110;

[0032] When the patient wears the traction cap body 100 on the head and the sliding plate 150 is located above the patient's ear, the arch wire 120 is connected to the cross plate 500 through the connecting assembly. At this time, when the arch wire 120 pulls the orthodontic appliance body 110, the arch wire 120 and the traction mechanism are likely to cause strangulation to the patient's ear. The sliding plate 150 drives the cross plate 500 to slide on the mounting frame 140 for position adjustment. Then, when the sliding plate 150 and the cross plate 500 are slid to a suitable position by the positioning assembly, the traction mechanism is positioned on the mounting frame 140 so that it can be staggered with the patient's ear. Compared with the existing ones, this kind of bracketless invisible braces traction cap can avoid the traction mechanism being located at the patient's ear during actual use, causing the patient's ear to be strangled by it, and the effect is better when used, making the bracketless invisible braces traction cap more applicable.

[0033] The mounting ring 130 is fixedly mounted on the traction cap body 100, and support blocks 141 are fixedly mounted at both ends of the mounting frame 140. One end of the support block 141 is fixedly mounted on the side wall of the mounting frame 140 to achieve the installation of the mounting frame 140 on the mounting ring 130.

[0034] In actual use, the appliance body 110 adopts a bracketless invisible appliance (which is the existing technology), and two arch wires 120 are arranged on the outside thereof.

[0035] like Figure 1-5 As shown, in this embodiment, one end of the arch wire 120 is bent to form a bent portion 200;

[0036] The connecting assembly includes a connecting plate 160 provided on the transverse plate 500 . The connecting plate 160 is provided with a plurality of connecting holes 161 along its height direction. The bending portion 200 is inserted into the connecting holes 161 to achieve the connection of the arch wire 120 on the connecting plate 160 .

[0037] In this embodiment, the bending portion 200, the connecting plate 160, and the connecting hole 161 are arranged so that the connecting plate 160 is fixedly mounted on the horizontal plate 500. When the bending portion 200 at one end of the arch wire 120 is engaged with the corresponding connecting hole 161, the arch wire 120 is connected to the connecting plate 160.

[0038] The bending portion 200 is inserted into the connecting hole 161 at different positions, so that the torque of the arch wire 120 pulling the appliance body 110 can be adjusted, thereby improving the use effect;

[0039] In actual use, a threaded protrusion 511 is fixedly installed on the horizontal plate 500, and the threaded protrusion 511 is threadedly connected to the lower end surface of the sliding plate 150, so as to realize the installation of the horizontal plate 500 on the sliding plate 150, that is, the installation of the connecting plate 160 on the sliding plate 150. When the sliding plate 150 slides, the connecting plate 160 can be driven to slide by the horizontal plate 500, thereby preventing the bending portion 200 from being stuck in the connecting hole 161 and the arch wire 120 from being located at the patient's ear, causing the patient's ear to be strangled by the arch wire 120.

[0040] like Figure 1-4 As shown, in this embodiment, a plurality of positioning holes 302 are provided on the side wall of the mounting ring 130 along its circumference, a cavity 301 is provided on the side wall of the sliding plate 150, and an intercepting ring 310 is provided at the opening of the cavity 301;

[0041] The positioning assembly includes a fixed plate 311 arranged in the cavity 301, and a fixed block 312 with one end passing through the sliding plate 150 is provided on one end face of the fixed plate 311. A spring 320 is provided in the cavity 301, and the spring 320 is used to push the fixed plate 311, and insert one end of the fixed block 312 into the positioning hole 302 to realize the sliding positioning of the sliding plate 150. The fixed plate 311 is also provided with a release member for releasing the positioning of the sliding plate 150.

[0042] In this embodiment, by setting the positioning hole 302, cavity 301, intercepting ring 310, fixing plate 311, fixing block 312, spring 320 and releasing member, the fixing block 312 is fixedly installed on the fixing plate 311, the intercepting ring 310 is fixedly installed at the opening of the cavity 301, and the fixing plate 311 and the spring 320 in the cavity 301 are intercepted, so that the fixing plate 311 and the spring 320 are installed in the cavity 301. When the spring 320 pushes the fixing plate 311 to move toward the bottom wall of the cavity 301, the fixing block 312 on the fixing plate 311 is inserted into the corresponding positioning hole 302, thereby realizing the sliding positioning of the sliding plate 150.

[0043] When the positioning of the sliding plate 150 needs to be released, the fixing plate 311 is driven to move by the releasing member so that the fixing block 312 on the fixing plate 311 slides out of the positioning hole 302, thereby releasing the positioning of the sliding plate 150 and allowing the sliding plate 150 to continue to slide on the mounting frame 140.

[0044] In actual use, the side walls of the sliding plate 150 are fixedly installed with limit blocks 340 for limiting the sliding of the sliding plate 150. The side walls of the limit blocks 340 slide and fit with the side walls of the mounting ring 130, making the sliding plate 150 more stable when sliding. At the same time, the limit blocks 340 can limit the rotation of the sliding plate 150, thereby preventing the sliding plate 150 from rotating, causing the fixed block 312 to be unable to be inserted into the positioning hole 302, affecting actual use.

[0045] like Figure 1-3 As shown, in this embodiment, the releasing member includes a fixing rod 330 provided on the other end face of the fixing plate 311, one end of the fixing rod 330 extends through the intercepting ring 310, and the fixing rod 330 is used to drive the fixing block 312 to slide out of the positioning hole 302, thereby releasing the positioning of the sliding plate 150.

[0046] In this embodiment, the fixing rod 330 is provided so that the other end of the fixing rod 330 is fixedly mounted on the fixing plate 311. When the fixing rod 330 is pulled outward, the fixing rod 330 can drive the fixing plate 311 to move, thereby sliding the fixing block 312 on the fixing plate 311 out of the positioning hole 302, thereby releasing the positioning of the sliding plate 150.

[0047] When it is actually used, a handle 331 for pulling the fixing rod 330 is fixedly installed on the protruding end of the fixing rod 330. The fixing rod 330 is moved by pulling the handle 331, which is convenient to use.

[0048] Working principle: First, wear the traction cap body 100 on the patient's head, and then occlude the braces body 110 on the patient's teeth. Then, pull the fixing rod 330 through the handle 331 to make the fixing block 312 on the fixing plate 311 slide out of the positioning hole 302. At this time, slide the sliding plate 150 to the appropriate position, release the handle 331, and insert the fixing block 312 on the fixing plate 311 into the corresponding positioning hole 302 to position the sliding plate 150. Finally, insert the bending part 200 on the arch wire 120 into the connecting hole 161 to realize the traction of the traction cap body 100 on the braces body 110 through the arch wire 120.

[0049] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
