Abstract
Description
Technical Field
[0001] The utility model relates to the field of orthodontics, in particular to an orthodontic micro-implant anchorage implantation positioning device. Background Technique
[0002] At present, micro-implant anchorage has become an important tool in the orthodontic process. The key to its function lies in the stability of the micro-implant anchorage. At present, the factors causing the instability of the micro-implant anchorage are mainly divided into the following two types. One is the inflammation around the micro-implant; the other is the poor implantation position and too close contact with the tooth root. The current mainstream orthodontic micro-implant anchorage-assisted implantation positioning device is a 3D-printed micro-implant guide plate. By integrating the CBCT jaw data and the micro-implant data obtained by MICROCT scanning of the three-dimensional dental arch model, a personalized implantation guide plate is manufactured by 3D printing. This device can determine the implantation site and implantation direction of the micro-implant at the same time, making the implanted implant consistent with the design scheme, improving the implantation accuracy, and ensuring the safety during the implantation process to the greatest extent. However, its design and manufacturing methods are relatively complex, the cost is relatively high, the manufacturing cycle is relatively long, and the clinical versatility is poor. Therefore, it is not widely used in clinical applications.
[0003] Therefore, it is necessary to provide a new orthodontic micro-implant anchorage implantation positioning device to solve the above technical problems. Content of the Utility Model

[0017] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0018] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.
[0019] Please refer to Figures 1 to 3 , an orthodontic micro-implant anchorage implantation positioning device provided by an embodiment of the present utility model, the orthodontic micro-implant anchorage implantation positioning device includes: a cross bar 1; a horizontal component is slidably fitted on the top of the cross bar 1, and the horizontal component can move on the cross bar 1; wherein, two groups of horizontal components are provided, and a vertical component is slidably fitted between the two groups of horizontal components, and the vertical component can move along the horizontal component; a fixing component is slidably fitted on one side of the cross bar 1, and the cross bar 1 can be fixed to a tooth through the fixing component.
[0020] It should be noted that: the cross bar 1 is a support carrier of the entire device, and the fixing component is provided to ensure that the device will not shift or loosen during the implantation process, providing a reliable fixing foundation. The horizontal component and the vertical component can be adjusted horizontally and vertically upward, facilitating the positioning operation. The horizontal component, the vertical component and the fixing component are all made of silicone or other soft plastics, having good elastic deformation performance and rigidity to maintain the physical shape of the device.
[0021] In an embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the horizontal component includes a slide rail 2 slidably connected to the top of the cross bar 1. A slider 21 is connected to the bottom of the slide rail 2. A slide groove 22 for the slider 21 to slide is provided on the top of the cross bar 1. A scale line 23 is engraved on the front surface of the slide rail 2.
[0022] It should be noted that: the horizontal component includes the slide rail 2, the slider 21 and the slide groove 22. The top of the cross bar 1 is connected to the slide rail 2, and the bottom of the slide rail 2 is connected to the slider 21. At the same time, a slide groove 22 for the slider 21 to slide is provided on the top of the cross bar 1. A scale line 23 is also engraved on the front surface of the slide rail 2 for more precise adjustment and positioning. The mutual cooperation of these components forms a movable structure, which can facilitate the movement and adjustment according to the tooth crown. The existence of the slide groove 22 makes the movement of the slider 21 more stable and not easily deviate from the predetermined position.
[0023] In an embodiment of the present utility model, please refer to Figure 1 and Figure 2, the vertical component includes a sliding piece 3. Lifting blocks 31 are connected to both sides of the sliding piece 3. Lifting grooves 32 for the lifting blocks 31 to slide are formed on the relatively close sides of the two slide rails 2. Locking grooves 33 are formed on the front surfaces of the two slide rails 2. Fixing bolts for locking the movement of the lifting blocks 31 are arranged on the front surfaces of the two slide rails 2. A positioning ball hole 34 is formed through the sliding piece 3.
[0024] It should be noted that: through the combined use of components such as the sliding piece 3, the lifting blocks 31, and the locking grooves 33, a highly flexible adaptation to the shape of the dental crown is achieved. The design of the lifting blocks 31 enables the sliding piece 3 to make slight adjustments in the vertical direction, which is crucial for adapting to the heights of different dental crowns. The existence of the lifting grooves 32 ensures the smooth movement of the lifting blocks 31 on the slide rails 2, while the locking grooves 33 and the fixing bolts can ensure that the lifting blocks 31 remain fixed after reaching the ideal position, avoiding unnecessary movement. In addition, the positioning ball hole 34 is provided for placing the positioning ball.
[0025] In an embodiment of the present invention, please refer to Figure 1 and Figure 3 , the fixing component includes two bending plates 4. The two bending plates 4 are both located on one side of the cross bar 1 and are slidably connected to the cross bar 1. Grooves are formed on one side of the tops of the two bending plates 4. Fixing plates 41 are slidably connected in the grooves. Spring grooves are formed on the two fixing plates 41. A plurality of springs 42 are installed in the two spring grooves. The two ends of the springs 42 are respectively abutted against the inner side walls of the bending plates 4 and the fixing plates 41. Bending portions are provided on the sides of the two fixing plates 41 away from the bending plates 4.
[0026] It should be noted that: the fixing component includes two bending plates 4. Sliding grooves are formed on the sides of the two bending plates close to the cross bar. Sliding blocks are slidably connected in the sliding grooves. One end of the sliding block penetrates through the sliding groove and is rotatably connected with a damping bearing. A key is rotatably connected to one side of the damping bearing. A key groove for the key to slide is formed on the cross bar 1. The bending plates 4 can move and adjust along the key groove, and can be adjusted up and down through the cooperation of the sliding blocks and the sliding grooves. Moreover, the bending plates 4 can also rotate through the connected damping bearings, and the damping bearings can limit the bending plates 4 by using their own characteristics. The design of the grooves of the bending plates 4 and the spring grooves of the fixing plates 41 enables adjustability, while the internal springs 42 provide a certain elastic force. The two ends of the springs 42 are respectively abutted against the inner side walls of the bending plates 4 and the fixing plates 41. This connection method can not only ensure that the fixing plates 41 can stretch and contract along the grooves, but also enable the fixing plates 41 to be fixed to the teeth through the bending portions after stretching.
[0027] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here too much.
[0028] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
