Description

Technical Field

[0001] This invention relates to the field of oral healthcare, and more specifically, to a silicone lingual clasp for orthodontic treatment. Background Technology

[0002] Orthodontics is the process of correcting teeth and correcting malocclusion. Orthodontics primarily studies the etiology and mechanisms of malocclusion, its diagnosis, analysis, prevention, and treatment, aiming to achieve aesthetically pleasing teeth. In orthodontic treatment, lingual clips act as hooks. To correct or prevent tooth rotation or tilting, lingual clips are often attached to the lingual side of canines, premolars, or rotated incisors. Sometimes, to facilitate intermaxillary traction with elastic bands, lingual clips are spot-welded to the lingual side of molar bands or directly bonded to the lingual surface of the teeth.

[0003] Chinese patent application publication number CN109758241B discloses a silicone sleeve for invisible lingual clasps in orthodontics. This silicone sleeve utilizes an open cavity formed between a baffle and a bracket, with the cavity aligned with an overflow hole on the side wall of the cylindrical part, to facilitate the collection of overflowing resin for reuse. At the same time, when fixing multiple lingual clasps, the elastic band can be inserted into the round hole on the partition formed between two arc-shaped grooves, resulting in strong stability.

[0004] However, when shaping the guide hole, a rod is usually inserted inside the silicone sleeve so that when the light-cured resin is molded, the rod is wrapped inside it. After the light-cured resin is molded on the tongue side, the rod is pulled out to shape the guide hole.

[0005] However, since the guide hole is formed by the insert rod, there is almost no gap between the formed guide hole and the insert rod, making it difficult to pull out the insert rod. In addition, the light-cured resin tends to stick to the insert rod under the action of adhesion during the molding process, and the sticking force can easily affect the removal of the insert rod, further increasing the difficulty of removing the insert rod. Summary of the Invention

[0006] 1. Technical problems to be solved

[0007] To address the problems existing in the prior art, the purpose of this invention is to provide an invisible lingual silicone sleeve for orthodontic use. This sleeve can create a gap between the guide hole and the shaping rod of the light-cured resin lingual sleeve after molding, thereby reducing the difficulty of removing the shaping rod.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A type of invisible lingual silicone sleeve for orthodontic use includes a silicone sleeve body, wherein the silicone sleeve body is a hollow structure with an opening on one side, and the silicone sleeve body is provided with:

[0011] A hole-forming rod is inserted into the inside of the silicone sleeve body to form a guide hole inside the light-cured resin, and the diameter of the hole-forming rod is reduced by melting inside the oral cavity;

[0012] Positioning components, installed on the silicone sleeve body, are used to position the hole-shaped rod;

[0013] A material injection unit, mounted on the silicone sleeve body, is used to inject light-curing resin into the interior of the silicone sleeve body.

[0014] Furthermore, the perforated shaping rod includes a fusible ring made of a fusible solid material, which is inserted into the interior of the silicone sleeve body via a positioning element. The fusible solid material is rock candy.

[0015] Furthermore, the interior of the fusible coil is provided with multiple layers of wire coils arranged sequentially from the inside to the outside. Each wire coil includes multiple equally spaced loop connectors, which are connected by multiple strip connecting lines arranged in a ring array.

[0016] Furthermore, the fusible ring is a ring-shaped structure with a central shaft inserted inside.

[0017] Furthermore, the positioning component includes a positioning head and an injection tube fixedly connected to the silicone sleeve body, and a fixing magnet is fixedly connected inside the positioning head.

[0018] Furthermore, the material injection component includes an injection tube fixed to the silicone sleeve body, the injection tube having an internally fitted movable bracket adapted to the shaft, and a sealing plug fitted on the injection tube.

[0019] Furthermore, the spindle includes a reinforcing rod, and a deformation extrusion part is provided on the outer side of the reinforcing rod. An adjustment unit adapted to the deformation extrusion part is also provided on the reinforcing rod.

[0020] Furthermore, the deformation extrusion part includes an expansion airbag assembled on the outside of the reinforcing rod, and an air cavity with one end open is opened inside the reinforcing rod. The adjustment unit includes a push plate slidably connected inside the reinforcing rod. The push plate is fixedly connected to and fixed with movable magnets that magnetically attract each other. A ventilation slot is opened on the side wall of the reinforcing rod at a position away from the air cavity opening.

[0021] Furthermore, a pull-out support rod extending to the outside of the reinforcing rod is fixedly connected to the thrust plate, and a pressing plate 16 is fixedly connected to one end of the pull-out support rod extending to the outside of the reinforcing rod.

[0022] Furthermore, the movable support includes an inner ring component, the inner diameter of which is clearance-fitted with the outer diameter of the reinforcing rod, and an outer support ring fixedly connected to the outer side of the inner ring component via a connecting rod, the outer diameter of which is clearance-fitted with the inner diameter of the injection pipe, and multiple material passages are formed between the outer support ring and the inner ring component.

[0023] 3. Beneficial Effects

[0024] Compared with the prior art, the advantages of this invention are:

[0025] This solution utilizes the temperature of the user's oral cavity to melt the hole-shaped rod, creating a gap between the guide hole and the hole-shaped rod on the tongue side of the molded UV-cured resin. This reduces the difficulty of removing the hole-shaped rod due to the small gap between the guide hole and the hole-shaped rod, and also reduces the impact of the UV-cured resin viscosity on the hole-shaped rod. Therefore, it effectively reduces the difficulty of removing the hole-shaped rod and makes it easier for the user to operate. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] Please see Figure 1-7 A type of invisible lingual silicone sleeve for orthodontic use includes a silicone sleeve body 1, which is a hollow structure with an opening on one side. The internal cavity is the shape of the lingual sleeve. By placing and filling light-cured resin into the silicone sleeve body 1, the light-cured resin can be shaped by the shape of the internal cavity of the silicone sleeve body 1. An opening is provided on one side of the silicone sleeve body 1, and the light-cured resin comes into contact with the user's teeth through the opening of the silicone sleeve body 1.

[0038] Furthermore, in order to facilitate the positioning of the rubber band by the light-cured resin tongue buckle after molding, the silicone sleeve body 1 is provided with a positioning component, a hole shaping rod and a material injection component.

[0039] Specifically, the hole-shaped rod is inserted into the inside of the silicone sleeve body 1 to form a guide hole inside the light-cured resin for the rubber band to pass through.

[0040] Furthermore, in order to facilitate the removal of the shaped rod from the guide hole after molding, the diameter of the shaped rod is reduced by melting inside the cavity, thereby melting the contact part between the shaped rod and the guide hole and creating a gap between the shaped rod and the guide hole, so that the shaped rod can be pulled out from the guide hole more easily.

[0041] The positioning component is installed on the silicone sleeve body 1 and is used to position the hole shaping rod;

[0042] The material injection component is also provided on the silicone sleeve body 1, and is used to inject light-curing resin into the interior of the silicone sleeve body 1.

[0043] In summary, this technical solution utilizes the temperature of the user's oral cavity to melt the hole-shaped rod, creating a certain gap between the guide hole and the hole-shaped rod on the tongue side of the molded light-cured resin. This reduces the difficulty caused by the small gap between the guide hole and the hole-shaped rod when pulling out the hole-shaped rod, and also reduces the influence of the viscosity of the light-cured resin on the hole-shaped rod. Therefore, it effectively reduces the difficulty of pulling out the hole-shaped rod and makes it easier for the user to operate.

[0044] Example 2:

[0045] Please see Figure 2-3 and Figure 6 As shown, this embodiment discloses the specific structure of the positioning component, the hole shaping rod and the material injection component based on embodiment 1. Specifically, the hole shaping rod includes a fusible ring 2 made of fusible solid material, and the fusible ring 2 is inserted into the inside of the silicone sleeve body 1 through the positioning component.

[0046] Furthermore, the fusible solid material is a material that can be melted at a temperature of 30℃~40℃. It melts automatically inside the oral cavity, causing the fusible solid material that is bonded to the inner wall of the guide hole to melt into a liquid. A gap is created between the remaining fusible solid material and the inner wall of the guide hole, making it relatively easy to remove the positioning rod from inside the guide hole.

[0047] Specifically, the preferred soluble solid material is rock sugar, which has the characteristic of melting inside the mouth and is non-toxic. The sugar water formed after melting can be consumed directly without adverse effects on the user's health.

[0048] To reduce the occurrence of fracture in the fusible ring 2, this technical solution employs two methods to strengthen the fusible ring 2.

[0049] Please see Figure 2-3 As shown, the first scheme is that the fusible ring 2 is a ring-shaped structure with a central shaft inserted inside. The central shaft can effectively support the fusible ring 2 and prevent it from breaking under stress.

[0050] Please see Figure 3 and Figure 6 As shown, another solution is to have multiple layers of wire coils 5 arranged sequentially from the inside to the outside inside the fusible coil 2. The wire coils 5 can act as reinforcing ribs to strengthen the fusible coil 2.

[0051] Specifically, the coil 5 includes multiple equally spaced loop connectors 52, which are connected by multiple strip connectors 51 arranged in a ring array.

[0052] Please refer to Figure 2-3 and Figure 7 As shown, the positioning component includes a positioning head 3 and an injection tube 4 fixedly connected to the silicone sleeve body 1. The silicone sleeve body 1, the positioning head 3, and the injection tube 4 are preferably integrally injection molded. A fixing magnet 11 is fixedly connected inside the positioning head 3. When installing the shaft rod, the shaft rod is inserted into the silicone sleeve body 1 through the injection tube 4, and one end of the shaft rod is inserted into the positioning head 3. The fixing magnet 11 can then attract and position the shaft rod, reducing the phenomenon of the shaft rod falling out of the silicone sleeve body 1.

[0053] Please refer to the following again. Figure 2-3As shown, the material injection component is also an injection tube 4 fixed on the silicone sleeve body 1. The light-curing resin can be injected into the silicone sleeve body 1 through the opening of the injection tube 4. In order to create sufficient gap inside the injection tube 4 while positioning the shaft rod, the injection tube 4 is equipped with a movable bracket 15 that matches the shaft rod for positioning the shaft rod. By using the same injection tube 4 for both the material injection component and the positioning component, the opening of the silicone sleeve body 1 can be effectively reduced, and the leakage of glue can be reduced.

[0054] In order to seal the injection tube 4, a sealing plug 14 is installed on the injection tube 4, which can seal the opening of the injection tube 4.

[0055] Example 3:

[0056] Please see Figure 2-4 As shown, this embodiment further discloses the structure of the shaft rod based on embodiment 2. Specifically, the shaft rod includes a reinforcing rod 6, and a deformation extrusion part is provided on the outer side of the reinforcing rod 6. During installation and disassembly, the shape of the deformation extrusion part can be changed to create a gap between the reinforcing rod 6 and the fusible ring 2, which facilitates the installation of the reinforcing rod 6 and the deformation of the extrusion part. The reinforcing rod 6 is also provided with an adjustment unit adapted to the deformation extrusion part, and the shape of the deformation extrusion part can be adjusted by adjusting the adjustment unit.

[0057] Please see Figure 3-4 As shown, the deformation extrusion section includes an expansion airbag 7 mounted on the outside of the reinforcing rod 6. Inflating the expansion airbag 7 adjusts its internal air pressure, causing the expansion airbag 7 to expand or contract. The reinforcing rod 6 has an air cavity 12 with one end open. The adjustment unit includes a push plate 9 slidably connected inside the reinforcing rod 6. A movable magnet 10 with magnetic attraction is fixedly connected to and fixed to a magnet 11. A ventilation slot 8 is provided on the side wall of the reinforcing rod 6 away from the opening of the air cavity 12. When the reinforcing rod 6 is inserted into the positioning head 3, under the magnetic force of the fixed magnet 11, the movable magnet 10 will drive the push plate 9 to slide towards the ventilation slot 8, pushing the gas inside the air cavity 12 into the expansion airbag 7, causing the expansion airbag 7 to expand and eliminating the gap between the reinforcing rod 6 and the fusible ring 2.

[0058] Meanwhile, in order to allow the inflatable airbag 7 to expand and position the fusible ring 2 when the reinforcing rod 6 is not inserted into the silicone sleeve body 1, a pull-out support rod 13 extending to the outside of the reinforcing rod 6 is also fixedly connected to the push plate 9. The position of the push plate 9 can be adjusted by pressing the pull-out support rod 13. In order to reduce the pain of pressing the pull-out support rod 13, a pressing plate 16 is fixedly connected to one end of the pull-out support rod 13 extending to the outside of the reinforcing rod 6.

[0059] Please see Figure 2-3and Figure 5 As shown, the specific structure of the movable support 15 is described in detail here. The movable support 15 includes an inner ring 151. The inner diameter of the inner ring 151 and the outer diameter of the reinforcing rod 6 are in clearance fit. The outer side of the inner ring 151 is fixedly connected to an outer support ring 152 by a connecting rod 153. The outer diameter of the outer support ring 152 and the inner diameter of the injection tube 4 are in clearance fit. At this time, multiple material passages 154 are formed between the outer support ring 152 and the inner ring 151. After the reinforcing rod 6 is inserted into the silicone sleeve body 1, the wire coil 5 is placed into the injection tube 4. The inner ring 151 is positioned through the material passages 154. Then, the reinforcing rod 6 is inserted into the inner ring 151 to position the reinforcing rod 6. Then, the light-curing resin can be supplied through the material passages 154.

[0060] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
