Abstract
Description
Technical Field
[0001] The utility model relates to the field of arch expansion appliances, in particular to an arch expansion appliance which can promote the development of dental arches. Background Art
[0002] With the development of economy, young people nowadays, for the sake of quality of life and their own appearance, some people with serious tooth deformities or insufficient aesthetics will improve their tooth structure to make them more neat and beautiful. Maxillary arch expansion is a commonly used orthodontic correction method. It is often a necessary treatment method for patients with narrow maxillary dentition and basal bone. The orthodontic appliance used is an expander. By placing the expansion coil spring in the appropriate position, rotating the spiral hole to enlarge the expander, and transmitting the orthodontic appliance to the teeth and alveolar bone through the support to expand the width and length of the maxillary dental arch, the inclination of the teeth can be gradually reduced and the teeth can be aligned during the process of tooth development.
[0003] Current arch expansion appliances must be supplemented with medication during use to promote the development and repair of the skeleton in the maxillary dental arch. However, oral medications are absorbed through the gastrointestinal tract first, so they take effect more slowly and have limited effect in promoting dental arch development.
[0004] Therefore, in view of the fact that the existing dental arch appliance, which is used in combination with oral medication to promote development, has a slow onset of effect, a dental arch appliance can be designed that stores sustained-release drugs to promote development. During use, the drug can be absorbed through the oral mucosa close to the dental arch bones, thereby increasing the speed of drug action and promoting accelerated development of the dental arch. Utility Model Content
[0005] In order to overcome the problem of slow effect of the existing dental arch appliance, oral medications are used to promote developmental treatment.
[0006] The technical solution of the utility model is: an arch expansion appliance capable of promoting dental arch development, comprising an appliance body, an arch expansion spiral column, a medicine bag cavity, a grid plate, a PVC mirror layer, and a rubber sleeve; the appliance body is a T-shaped structure and is provided with adjustable and retractable arch expansion spiral columns on three sides, a medicine bag cavity for storing slow-release development-promoting drugs is provided on the other side of the appliance body, a flip-movable grid plate is installed at the opening of the medicine bag cavity, PVC mirror layers are provided on the upper and lower surfaces of the appliance body, and a rubber sleeve that elastically deforms with the telescopic movement of the arch expansion spiral column is fixedly connected to the arch expansion spiral column.
[0007] Preferably, a drug capsule cavity for storing development-promoting drugs is provided on the original arch expansion appliance. Through the grid plate, saliva contacts the drug to promote drug dissolution. The dissolved drug is slowly absorbed by the oral mucosa and directly acts on the nearby dental arch bones. Compared with traditional oral gastrointestinal absorption, it can promote periodontal bone development faster. When inspecting the dental arch, the PVC mirror layer reflects the oral environment and expands the inspection area. The rubber sleeve wraps the arch expansion spiral column to prevent food residues from contacting the external thread structure.
[0008] Preferably, the side wall of the appliance body is provided with an inlay around the expansion spiral column, one end of the rubber sleeve is molded with an inlay ring embedded and fixed in the inlay ring, and the inner wall of the other end of the rubber sleeve is provided with a connecting ring which is hot-melt fixed to the end of the expansion spiral column. The rubber sleeve has good elastic deformation ability and fits tightly to the outer wall of the expansion spiral column exposed outside the appliance body. When the expansion spiral column rotates and retracts, due to the hot-melt connection of the connecting ring and the fixing effect of the inlay ring and the inlay ring, the rubber sleeve follows the expansion spiral column to retract and retract, and always covers the outer surface of the expansion spiral column.
[0009] Preferably, the rubber sleeve is made of food-grade silicone material with a wall thickness of 1 mm. An elastic thin layer with a thickness of 0.5 mm is provided on the outer wall of the rubber sleeve close to the embedded ring. The elastic thin layer is used as an auxiliary deformation structure of the rubber sleeve. Because the material is thinner, it deforms preferentially here when subjected to force. Food-grade silicone material is also safer to use.
[0010] Preferably, the sustained-release development-promoting drug stored in the medicine capsule cavity is a vitamin and calcium mixture drug coated with a rice coating, and the inner wall of the medicine capsule cavity is provided with an anti-corrosion coating layer. The vitamin and calcium mixture drug has the effect of promoting the development of teeth and bones and accelerating the growth of bone cells. The structure coated with a rice coating is used to slowly dissolve the drug coating with the help of saliva to achieve a sustained-release effect, and the anti-corrosion coating layer prevents the inner wall of the medicine capsule cavity from being oxidized due to long-term contact with the drug.
[0011] Preferably, the PVC mirror layer is a food-grade PVC mirror panel, and the PVC mirror panel is covered with a food-grade transparent acrylic protective layer. When the doctor uses a flashlight to examine the oral dental arch and orthodontic appliance, other parts of the oral cavity can be directly observed through the mirror reflection of the PVC mirror layer, and the inspection area is wider. The transparent acrylic protective layer also plays a further protective role for the PVC mirror panel.
[0012] Preferably, the left and right side walls of the medicine bag cavity are fixedly connected with shaft heads, and the left and right ends of the grid plate are fixedly connected with shaft seats rotatably connected to the shaft heads. The grid plate is flipped around the shaft heads as the axis. After opening, the medicine can be stuffed into the medicine bag cavity.
[0013] Preferably, a No. 1 magnetic attraction piece is fixedly installed on the top wall of the medicine bag cavity, and a No. 2 magnetic attraction piece is fixedly installed on the upper end of the grille plate. Both the No. 1 magnetic attraction piece and the No. 2 magnetic attraction piece are rubber magnetic strips covered with food-grade silicone. After the grille plate is flipped over to close the medicine bag cavity, the No. 1 magnetic attraction piece and the No. 2 magnetic attraction piece are adsorbed together to prevent the grille plate from flipping open and the medicine from falling out. The food-grade silicone protects the rubber magnetic strips and prevents oral damage.
[0014] Beneficial effects of the utility model:
[0015] 1. By setting a drug capsule cavity for storing development-promoting drugs on the original arch expansion appliance, drugs can be regularly added during the correction process, dissolved by saliva and absorbed by the oral mucosa, which can promote periodontal bone development faster than traditional oral gastrointestinal absorption;
[0016] 2. The PVC mirror layer on the appliance body can be used to reflect other parts of the oral cavity when inspecting the dental arch, with the help of lighting tools such as flashlights, which helps doctors expand their observation area.
[0017] 3. Use the rubber sleeve to isolate the surface of the expansion spiral column to prevent food residues from sticking to the external thread of the expansion spiral column and becoming difficult to clean during the wearing of the braces. BRIEF DESCRIPTION OF THE DRAWINGS

The rubber sleeve 6 has good elastic deformation ability and fits tightly with the outer wall of the expansion spiral column 2 exposed outside the appliance body 1. When the expansion spiral column 2 rotates and retracts, due to the hot-melt connection of the connecting ring 9 and the fixing effect of the inlay ring 8 and the inlay 7, the rubber sleeve 6 follows the expansion spiral column 2 to retract and change, and always covers the outer surface of the expansion spiral column 2. The rubber sleeve 6 is made of food-grade silicone material, and the wall thickness of the rubber sleeve 6 is 1 mm. A thin elastic layer 10 with a thickness of 0.5 mm is provided on the side of the outer wall of the rubber sleeve 6 close to the inlay ring 8. The thin elastic layer 10 is used as an auxiliary deformation structure of the rubber sleeve 6. Because the material is thinner, it is deformed here first when subjected to force, and the food-grade silicone material is safer to use.
[0026] See also Figure 2 and 4In this embodiment, the sustained-release development-promoting drug stored in the drug capsule cavity 3 is a vitamin and calcium mixed drug coated with a rice coating. The inner wall of the drug capsule cavity 3 is provided with an anti-corrosion coating layer. The vitamin and calcium mixed drug has the effect of promoting the development of teeth and bones and accelerating the growth of bone cells. The structure coated with rice coating is used to slowly dissolve the drug coating with the help of saliva to achieve a sustained-release effect. The anti-corrosion coating layer prevents the inner wall of the drug capsule cavity 3 from being in long-term contact with the drug and oxidation. The PVC mirror layer 5 is a food-grade PVC mirror panel, and the PVC mirror panel is covered with a food-grade transparent acrylic protective layer. When the doctor uses a flashlight to inspect the oral dental arch and the orthodontic appliance, the other parts of the oral cavity can be directly observed through the mirror reflection of the PVC mirror layer 5, and the inspection area is wider.

The grid plate 4 is flipped with the shaft head 11 as the axis. After opening, the medicine can be stuffed into the medicine bag cavity 3. A No. 1 magnetic suction piece 13 is fixedly installed on the top wall of the medicine bag cavity 3, and a No. 2 magnetic suction piece 14 is fixedly installed on the upper end of the grid plate 4. The No. 1 magnetic suction piece 13 and the No. 2 magnetic suction piece 14 are both rubber magnetic strips covered with food-grade silicone. After the grid plate 4 is flipped over to close the medicine bag cavity 3, the No. 1 magnetic suction piece 13 and the No. 2 magnetic suction piece 14 are adsorbed together to prevent the grid plate 4 from flipping open and the medicine from falling out. The food-grade silicone protects the rubber magnetic strips and prevents oral damage.
[0027] During operation, after the appliance body 1 is installed in the maxillary part of the oral cavity, the expansion spiral column 2 is adjusted and retracted according to the size of the oral structure of the user, and the expansion spiral column 2 is controlled to fully abut against the dental arch bone. As the expansion spiral column 2 is retracted and adjusted, the rubber sleeve 6 is deformed synchronously and always covers the outer surface of the expansion spiral column 2.
[0028] In daily use, the user opens the mouth, moves the grid plate 4 with the hand, and turns it over with the shaft head 11 as the axis to open the medicine capsule cavity 3, and then puts the vitamin and calcium mixed medicine covered with rice coating into the medicine capsule cavity 3, and then turns the grid plate 4 over to close the medicine capsule cavity 3, and the grid plate 4 and the medicine capsule cavity 3 are locked by adsorbing the first magnetic suction piece 13 and the second magnetic suction piece 14 together;
[0029] As the drug is dissolved by saliva, it is released outward through the grid plate 4, absorbed by the oral mucosa and gums, and directly acts on the dental arch bones to promote development.
