Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, specifically a sliding straight wire buccal tube. Background Technology

[0002] In orthodontics, clear aligner technology is currently popular. One of the challenges of clear aligner technology is controlling the "axis" of the teeth to prevent tilting, especially in cases involving tooth extraction. In clinical practice, for cases with crowded teeth or requiring improvement in overbite, after extracting one or more teeth (usually premolars), the adjacent teeth have considerable room for movement. The treatment plan needs to close the gaps by gradually moving the teeth. However, during the process of moving teeth while wearing polymer plastic braces, because the plastic braces only exert force on the crowns, individual teeth may tilt or fall, significantly negatively impacting the treatment and preventing the desired results. A search revealed an adjustable type I buccal tube disclosed in Chinese patent CN220938192U, including an adhesive plate and an actuating part. An archwire block is mounted on one side of the adhesive plate, and a reinforcing plate is mounted on one side of the archwire block. The outer wall of the reinforcing plate has tubular components. The actuating part is slidably connected inside the pipe fitting. The outer wall of the pipe fitting has a hole, and a fastening screw is threaded inside the hole. An anti-detachment mechanism is provided inside the hole. The anti-detachment mechanism includes a pressure plate, a clamping plate, a spring, and a washer. The pressure plate has sliding holes on both sides. The clamping plate is slidably connected inside the two sliding holes. The inner walls of the holes have grooves that engage with the clamping plates on both sides. A spring is connected to one side of the inner wall of each of the two sliding holes. One end of the spring is connected to one side of the clamping plate.

[0003] Currently, existing buccal tubes require positional adjustments based on the distribution of the upper and lower teeth during use. Once the position changes, the active part of the buccal tube also shifts. If the active part faces the inside of the mouth, subsequent operations will be more inconvenient. Utility Model Content

[0004] To address the problem that the working part of existing buccal tubes is not easy to adjust, this invention provides a sliding straight wire buccal tube.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A sliding straight wire bow cheek tube includes an adhesive part and a fixing part on the top surface for clamping the bowwire. An outer cylinder is connected to one side of the fixing part. An active part is inserted inside the outer cylinder. The outer wall of the active part is provided with triangularly distributed insertion holes. An elastic pad is provided inside the insertion holes. A through hole is provided on one side of the outer wall of the outer cylinder. A pin assembly for squeezing the elastic pad is provided inside the through hole.

[0006] Furthermore, the elastic pad includes a block and a return spring, the block is slidably connected inside the socket, the return spring is connected to one side of the block, and one end of the return spring is connected to the inside side of the socket.

[0007] The beneficial effect of adopting the above-mentioned further solution is that, through the elastic action of the return spring on the block, the top of the block can be kept flush with the top surface of the insertion hole, thereby keeping the outside of the working part flat.

[0008] Furthermore, the pin assembly includes a pin block and a compression spring, with the pin block slidably connected inside the through hole, and a compression spring for pressing down is sleeved on the outer wall of the pin block.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the elastic action of the compression spring on the pin block, the pin block 701 can maintain its orientation toward the insertion hole, so that once the insertion hole and the through hole are aligned and connected, the pin block will extend into the interior of the insertion hole, thereby fixing the working part.

[0010] Furthermore, the adhesive portion includes a reinforcing plate and an adhesive pad, and the top block of the adhesive pad has a hole for placing the reinforcing plate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the reinforcing plate is embedded in the hole of the adhesive pad, which can enhance the overall structural strength of the bonding part, avoid the deformation or breakage of the adhesive pad caused by long-term stress on the buccal tube, ensure the bonding stability between the buccal tube and the teeth, and prevent the buccal tube from falling off during the orthodontic process.

[0012] Furthermore, the fixing part includes a housing, the bottom surface of which is connected to the top surface of the reinforcing plate, and an insert block is slidably connected inside the housing. The insert block has a through hole inside that matches the bowwire.

[0013] The advantage of adopting the above-mentioned further solution is that the sliding connection between the outer shell and the insert makes the two form a detachable structure, which facilitates the disassembly and assembly of the bowwire.

[0014] Furthermore, the bowwire includes a wire body, one end of which extends through to the outside of the outer shell and is fitted with a limiting ring.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by using the limiting ring, one end of the wire can be fixed, preventing it from detaching from the fixing part.

[0016] Furthermore, a pin is inserted into one side of the outer wall of the limiting ring, and a through hole matching the pin is opened on one side of the wire.

[0017] The advantage of adopting the above-mentioned further solution is that the pin inserted through the through hole makes it easy to fix the limiting ring to one end of the wire body.

[0018] Furthermore, one side of the outer wall of the insert is fixedly connected to one end of the outer cylinder.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the overall structure of the cheek tube remains stable through the cooperation of the insert and the outer cylinder.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This sliding straight wire buccal tube, through the coordinated use of an outer cylinder, an actuating part, an elastic pad, and a pin assembly, allows the buccal tube to adjust the orientation of the actuating part as needed. The bonding part stably fixes the buccal tube to the buccal surface of the teeth, providing basic support for subsequent orthodontic operations. The fixing part on the top surface is used to hold the archwire, transmitting orthodontic force through the archwire to achieve tooth position adjustment. The outer cylinder on one side of the fixing part provides installation and sliding space for the actuating part, which can move axially along the outer cylinder to adapt to the archwire position requirements at different stages of orthodontic treatment. The triangularly distributed insertion holes on the outer wall of the actuating part facilitate the fixing of the pin assembly at different rotation angles, thus allowing the actuating part to face different directions. Due to subsequent operations, and the elastic action of the return spring on the block, the top of the block can remain flush with the top surface of the insertion hole. The pin assembly inside the through-hole in the outer wall of the outer cylinder can compress the elastic pad. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] As an embodiment of this utility model, the elastic pad 6 further includes a block 601 and a return spring 602. The block 601 is slidably connected inside the socket, and the return spring 602 is connected to one side of the block 601. One end of the return spring 602 is connected to the inside side of the socket. Through the elastic action of the return spring 602 on the block 601, the top of the block 601 can be kept flush with the top surface of the socket, thereby keeping the exterior of the working part 5 flat. The pin assembly 7 includes a pin 701 and a compression spring 702. The pin 701 is slidably connected inside the through hole, and the outer wall of the pin 701 is fitted with a compression spring 702 for pressing down. Through the elastic action of the compression spring 702 on the pin 701, the pin 701 can maintain a tendency to face the socket. Once the socket and the through hole are aligned and connected, the pin 701 will extend into the interior of the socket, thereby fixing the working part 5.

[0027] As an embodiment of this utility model, the bonding part 1 further includes a reinforcing plate 101 and an adhesive pad 102. The top block of the adhesive pad 102 has a hole for placing the reinforcing plate 101.

[0028] As an embodiment of this utility model, the fixing part 2 further includes a housing 201, the bottom surface of which is connected to the top surface of the reinforcing plate 101. An insert block 202 is slidably connected inside the housing 201. The insert block 202 has a through hole 203 that matches the bowwire 3. The sliding connection between the housing 201 and the insert block 202 allows for a detachable structure, facilitating the disassembly and assembly of the bowwire 3. The bowwire 3 includes a wire body 301. One end of the wire 301 extends through the outside of the outer shell 201 and is fitted with a limiting ring 302. The limiting ring 302 can fix one end of the wire 301 and prevent it from falling off the fixing part 2. A pin 303 is inserted through one side of the outer wall of the limiting ring 302. A through hole 304 that matches the pin 303 is opened on one side of the wire 301. By inserting the pin 303 through the through hole 304, it is easy to fix the limiting ring 302 to one end of the wire 301.

[0029] As an embodiment of this utility model, one side of the outer wall of the insert 202 is fixedly connected to one end of the outer cylinder 4. Through the cooperation of the insert 202 and the outer cylinder 4, the overall structure of the cheek tube remains stable.

[0030] Specifically, the working principle of this sliding straight wire buccal tube is as follows: First, it is fixed to the teeth via the adhesive part 1. A reinforcing plate 101 is embedded into the hole of the adhesive pad 102. The adhesive pad's adhesion secures the buccal tube to the buccal surface of the teeth. The reinforcing plate strengthens the adhesive part structure, preventing deformation and detachment of the adhesive pad due to long-term stress, thus providing a stable foundation for subsequent orthodontic treatment. When installing the archwire 3, the insert 202 inside the sliding fixing part 2 housing 201 is slid to expose the perforation 203 inside the insert. The archwire 301 is inserted into the perforation, and the insert is reset. Then, a limiting ring 302 is fitted onto the end of the archwire that penetrates the housing. A pin 303 is inserted, passing through the limiting ring and the through hole 304 of the archwire, fixing the position of the limiting ring and preventing the archwire 3 from coming out of the perforation, ensuring stable clamping of the archwire 3. When adjusting according to orthodontic needs, the outer cylinder 4 and the action part 5 work together to achieve multi-dimensional adjustment: when it is necessary to adjust the extension length or flip direction of the action part, press the pin block 701 of the pin assembly 7, the compression spring 702 is compressed and the pin block 701 is withdrawn from the insertion hole of the action part 5, releasing the fixation of the action part; move or flip the action part to the target position, when another set of triangularly distributed insertion holes on the outer wall of the action part 5 are aligned with the through hole of the outer cylinder, the compression spring 702 resets and pushes the pin block 701 to insert into the new insertion hole, re-fixing the action part, at the same time the reset spring 602 in the insertion hole of the action part 5 pushes the block 601 to keep it flush with the top surface of the insertion hole, ensuring that the outside of the action part is flat.
