Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral medical device technology, specifically to a device for removing enamel from adjacent surfaces of invisible orthodontic aligners. Background Technology
[0002] In the process of invisible orthodontic treatment, interproximal enamel reduction is a routine method to create space between teeth and relieve crowding. Interproximal enamel reduction, also known as "tooth reduction," refers to the use of appropriate instruments to remove a certain amount of enamel from the interproximal surfaces of two adjacent teeth to reduce the mesiodistal width of the teeth, providing some space for crowded teeth and reducing the possibility of tooth extraction. It is often used in mild to moderate cases of dental crowding.
[0003] Currently, the common practice is to mount a diamond abrasive strip onto a saw frame to create an interproximal enamel removal instrument. During use, the operator holds both ends of the saw frame and moves it back and forth, using the diamond abrasive strip to remove a certain amount of enamel from the interproximal surfaces of the teeth. This process requires precise control of the amount removed to avoid excessive damage to the teeth. However, the inventors of this application have found through clinical use that the process of removing enamel from the interproximal surfaces of teeth using diamond abrasive strips is currently primarily performed inside the oral cavity. Due to the relatively small space inside the mouth, the back-and-forth movement with both hands is inconvenient and laborious. Utility Model Content
[0004] The existing procedure of removing enamel from the proximal surfaces of teeth using diamond strips mounted on a saw frame is currently performed primarily inside the oral cavity. Due to the limited space inside the oral cavity, the manual back-and-forth movement of the hands is inconvenient and laborious. This invention provides an invisible enamel removal device for proximal surfaces of teeth.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A device for removing enamel from adjacent surfaces of invisible orthodontic aligners includes a housing with an internal cavity. The cavity contains a power supply, a cylinder controller, and a telescopic cylinder. The power supply is connected to the cylinder controller to provide power. A power button is located on the surface of the housing. The output of the cylinder controller is electrically connected to the telescopic cylinder. The piston rod of the telescopic cylinder is connected to a drive shaft extending out of the cavity. An arc-shaped frame is connected to the outer end of the drive shaft. A diamond strip is fixedly connected between the two ends of the arc-shaped frame. A water channel is located inside the crossbeam of the arc-shaped frame. A water inlet is located at the top of the crossbeam, communicating with the water channel. A water inlet connector is fixedly connected to the water inlet. Several water outlets communicating with the water channel are located at the bottom of the crossbeam, with atomizing nozzles fixedly connected to each outlet.
[0007] Compared with existing technologies, the invisible orthodontic enamel removal device provided by this utility model connects the arched frame with the diamond strip to the piston rod of the telescopic cylinder located in the housing cavity via a drive shaft. Therefore, when using this device, the user first holds the housing by hand, then presses the power button. The cylinder controller is then connected to the power supply. Under the control of the cylinder controller, the piston rod of the telescopic cylinder drives the diamond strip on the arched frame to reciprocate, removing a certain amount of enamel from the proximal surfaces of the teeth. Since it is not necessary to manually hold both ends of the arched frame to move it back and forth in the mouth, only the user needs to hold the housing outside the mouth to operate it, making it very convenient and easy to use. Simultaneously, by setting a water inlet connector at the top of the beam and an atomizing nozzle at the bottom of the beam, when using this device, by connecting an external water inlet pipe to the water inlet connector, the external water passes through the atomizing nozzle to form a water mist that promptly removes the enamel produced by the diamond strip during enamel removal, preventing enamel from adhering to the diamond strip and affecting the quantitative gap of the grinding of adjacent teeth.
[0008] Furthermore, the shell is a rod-shaped shell.
[0009] Furthermore, mounting seats are fixedly connected to both ends of the bow-shaped frame, and the outer end of the drive shaft is connected to either of the mounting seats at both ends of the bow-shaped frame. The mounting seats are provided with mounting grooves, and the two ends of the diamond strip are respectively locked in the two mounting grooves. The mounting seats are provided with fixing screws that abut against the diamond strip.
[0010] Furthermore, the diamond strip has multiple through holes. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] Please refer to Figure 1 As shown, this utility model provides an enamel removal device for adjacent surfaces of invisible orthodontic treatment, including a housing 1. The housing 1 has an internal storage cavity containing a power supply 2, a cylinder controller 3, and a telescopic cylinder 4. The power supply 2 and the cylinder controller 3 are connected by wires to provide power. The power supply 2 can be implemented using an existing lithium battery. The cylinder controller 3 can be implemented using an existing PLC controller or a TPC8-8TD type controller. A power button 5 is provided on the surface of the housing 1 to control the power supply. The output terminal of the cylinder controller 3 is connected to the telescopic cylinder... The cylinder 4 is electrically connected. The piston rod end of the telescopic cylinder 4 is connected to a drive shaft 6 that extends out of the storage cavity. The outer end of the drive shaft 6 is connected to an arc-shaped frame 7. A diamond strip 8 is fixedly connected between the two ends of the arc-shaped frame 7. A water channel is provided inside the crossbeam 71 of the arc-shaped frame 7. A water inlet interface communicating with the water channel is provided at the top of the crossbeam 71. A water inlet connector 72 is fixedly connected to the water inlet interface. The water inlet connector 72 is suitable for connecting to an external water inlet pipe. Several water outlet interfaces communicating with the water channel are provided at the bottom of the crossbeam 71. An atomizing nozzle 73 is fixedly connected to the water outlet interface.
[0017] Compared with existing technologies, the invisible orthodontic enamel removal device provided by this utility model connects the arched frame with the diamond strip to the piston rod of the telescopic cylinder located in the housing cavity via a drive shaft. Therefore, when using this device, the user first holds the housing by hand, then presses the power button. The cylinder controller is then connected to the power supply. Under the control of the cylinder controller, the piston rod of the telescopic cylinder drives the diamond strip on the arched frame to reciprocate, removing a certain amount of enamel from the proximal surfaces of the teeth. Since it is not necessary to manually hold both ends of the arched frame to move it back and forth in the mouth, only the user needs to hold the housing outside the mouth to operate it, making it very convenient and easy to use. Simultaneously, by setting a water inlet connector at the top of the beam and an atomizing nozzle at the bottom of the beam, when using this device, by connecting an external water inlet pipe to the water inlet connector, the external water passes through the atomizing nozzle to form a water mist that promptly removes the enamel produced by the diamond strip during enamel removal, preventing enamel from adhering to the diamond strip and affecting the quantitative gap of the grinding of adjacent teeth.
[0018] As a specific embodiment, the housing 1 is a rod-shaped housing, which makes it very convenient for manual operation by holding the rod-shaped housing by hand.
[0019] For a specific embodiment, please refer to Figure 1 As shown, mounting seats 74 are fixedly connected to both ends of the bow-shaped frame 7. The outer end of the drive shaft 6 is connected to either mounting seat 74 at either end of the bow-shaped frame 7. Mounting slots are provided on the mounting seats 74. The two ends of the diamond strip 8 are respectively locked in the two mounting slots. Fixing screws 9 that abut against the diamond strip 8 are provided on the mounting seats 74. This can effectively prevent the diamond strip 8 from loosening when it moves back and forth in the oral cavity, and effectively improve the quality of interproximal enamel abrasion.
[0020] For a specific embodiment, please refer to Figure 1 As shown, the diamond strip 8 has multiple through holes 81 with small diameters. When the diamond strip 8 moves back and forth in the oral cavity to remove enamel, the removed enamel can fill the multiple through holes 81. The water mist formed by the atomizing nozzle 73 removes the enamel in the through holes 81 in time, thereby quickly removing the enamel dust generated during enamel removal and ensuring a quantitative gap for the removal of adjacent tooth surfaces.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
