Description

Technical Field

[0001] This utility model relates to the field of implant locators, and more specifically, to a dental implant locator based on 3D printing. Background Technology

[0002] Dental implant locators are key auxiliary tools in dental implant surgery. They are customized based on data such as the patient's oral CT scan and mainly consist of a positioning frame and a guide channel. During surgery, the locator is precisely fixed in the patient's mouth, and its guide channel indicates the precise position, angle, and depth for implant placement, just like installing a "navigation system" for the implant. With its help, doctors can improve surgical precision, reduce surgical trauma, shorten surgical time, reduce surgical risks, and increase the success rate of dental implants, thus ensuring that patients achieve more ideal implant restoration results.

[0003] In existing technologies, to ensure the compatibility of the locator with the oral cavity, 3D high-precision scanning combined with 3D printing is usually used to ensure a high degree of fit. After the locator is manufactured, it needs to be installed on the bracket to facilitate operation and installation steps. However, in existing technologies, the locator is usually fixed with bolts, and both the upper and lower locators need to be fixed, which is inefficient and has certain shortcomings. In view of this, we propose a dental implant locator based on 3D printing. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the current method of fixing the positioner usually relies on bolts, which requires fixing both the upper and lower positioners, resulting in low fixing efficiency.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a 3D-printed dental implant locator, comprising an implant locator body and a support frame. The implant locator body has a slot on its surface near the support frame. Both the support frame and the implant locator body have two slots. A central shaft is positioned between the two support frames, and both support frames are rotatably fitted onto the outer surface of the central shaft. A insertion post is fixedly connected to the surface of the support frame near the implant locator body. Reception grooves are formed on both the upper and lower surfaces of the insertion post. A rotating plate is rotatably connected inside the reception groove. A torsion spring is fixedly connected between the end of the rotating plate and the inner wall of the reception groove. A movement groove is formed inside the support frame. Sliding grooves are formed inside the insertion post and on the inner wall of the movement groove. The two sliding grooves are interconnected, and an unlocking component is provided inside each sliding groove.

[0006] As a preferred technical solution of this application, the unlocking component includes a mounting ring, which is fixedly connected to the inner wall of the sliding groove, and a displacement rod is slidably sleeved on the inner wall of the mounting ring.

[0007] As a preferred technical solution of this application, the storage groove of the displacement rod is connected to the interior of the sliding groove, and a first cable is fixedly connected to the adjacent side surface of the two rotating plates, and the end of the first cable is fixedly connected to the displacement rod.

[0008] As a preferred technical solution of this application, a displacement disk is fixedly connected to the end of the displacement rod, and a first spring is fixedly connected between the displacement disk and the mounting ring.

[0009] As a preferred technical solution of this application, a second cable is fixedly connected between the displacement disk and the motion groove, the lower side of the motion groove extends out of the lower surface of the bracket, and a U-shaped plate is slidably sleeved on the outer surface of the bracket.

[0010] As a preferred technical solution of this application, a push rod is fixedly connected to the lower surface of the U-shaped plate, and the lower end of the push rod slides through the interior of the motion groove.

[0011] As a preferred technical solution of this application, a second spring is fixedly connected between the lower surface of the U-shaped plate and the upper surface of the bracket, and a threaded post is fitted inside the central shaft.

[0012] As a preferred technical solution of this application, the upper end of the threaded column extends out of the upper end of the central shaft, and a pressure ring is sleeved on the outer surface of the threaded column, with the lower surface of the pressure ring contacting the upper surface of the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. It makes the installation and removal of the dental implant locator body more convenient, reduces the number of operation steps in the installation and removal process, and thus enables the quick replacement of different dental implant locator bodies;

[0016] 2. When the two supports unfold and drive the implant locator body to unfold for operation, the central axis can be pinched and the threaded column rotated. The vertical movement of the threaded column during rotation will drive the pressure ring to squeeze the supports, thereby locking the supports and preventing them from rotating freely and obstructing the operation.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A 3D-printed dental implant locator includes an implant locator body 1 and a bracket 2. The implant locator body 1 has a slot 3 on its surface near the bracket 2. Both the bracket 2 and the implant locator body 1 have two brackets, and a central shaft 4 is positioned between the two brackets 2. Both brackets 2 are rotatably fitted onto the outer surface of the central shaft 4. A insertion post 5 is fixedly connected to the surface of the bracket 2 near the implant locator body 1. The upper and lower surfaces of the insertion post 5 have storage grooves 7. A rotating plate 6 is rotatably connected inside the storage groove 7. A torsion spring is fixedly connected between the end of the rotating plate 6 and the inner wall of the storage groove 7. A movement groove 8 is formed inside the bracket 2. A sliding groove 9 is formed inside the insertion post 5 and on the inner wall of the movement groove 8. The two sliding grooves 9 are interconnected. An unlocking component is provided inside the sliding groove 9, which facilitates the installation and removal of the implant locator body 1, reduces the number of steps during installation and removal, and enables quick replacement of different implant locator bodies 1.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the unlocking component includes a mounting ring 10, which is fixedly connected to the inner wall of the sliding groove 9. A displacement rod 11 is slidably sleeved on the inner wall of the mounting ring 10. The storage groove 7 of the displacement rod 11 communicates with the interior of the sliding groove 9. A first cable 12 is fixedly connected to one of the adjacent surfaces of the two rotating plates 6. The end of the first cable 12 is fixedly connected to the displacement rod 11. A displacement disk 13 is fixedly connected to the end of the displacement rod 11. A first spring 14 is fixedly connected between the displacement disk 13 and the mounting ring 10. A second cable 15 is fixedly connected between the displacement disk 13 and the moving groove 8. The lower side of the moving groove 8 extends out of the lower surface of the bracket 2. A U-shaped plate 16 is slidably sleeved on the outer surface of the bracket 2. The lower surface of the horizontal plate of the U-shaped plate 16... A push rod 17 is fixedly connected, and the lower end of the push rod 17 slides through the interior of the movement groove 8. A second spring 19 is fixedly connected between the lower surface of the U-shaped plate 16 and the upper surface of the bracket 2. A threaded post 20 is threaded inside the central shaft 4, and the upper end of the threaded post 20 extends out of the upper end of the central shaft 4. A pressure ring 18 is fitted on the outer surface of the threaded post 20, and the lower surface of the pressure ring 18 contacts the upper surface of the bracket 2. When the two brackets 2 are unfolded and the implant locator body 1 is unfolded for operation, the central shaft 4 can be pinched and the threaded post 20 can be rotated. The vertical movement of the threaded post 20 during rotation will cause the pressure ring 18 to squeeze the bracket 2, thereby locking the bracket 2 and preventing it from rotating freely and hindering the operation.

[0030] The inside of the insertion slot needs to have protrusions or folds to facilitate the locking of the rotating plate.

[0031] The usage process of the 3D-printed dental implant locator provided by this utility model is as follows:

[0032] When fixing the implant locator body 1 and the bracket 2, simply align the slot 3 on the implant locator body 1 with the insertion post 5 and push it in. As the insertion post 5 enters the slot 3, it presses against the rotating plate 6, causing it to be pushed into the receiving groove 7. When the implant locator body 1 is disengaged from the insertion post 5, the rotating plate 6 unfolds under the action of the torsion spring, preventing the insertion post 5 from disengaging, thus completing the fixation. To unlock, simply press the U-shaped plate 16. The U-shaped plate 16 moves downwards under force. This movement of the U-shaped plate 16 drives the push rod 17 and compresses the second spring 19. After the push rod 17 moves, it contacts the second cable 15 and... The push rod 17 forces the second cable 15 to deform, which in turn pulls the displacement rod 11 to move. When the displacement rod 11 moves, it stretches the first spring 14 with the help of the displacement plate 13. At the same time, after the displacement rod 11 moves, the second cable 15 pulls the rotating plate 6 back into the storage slot 7 to complete the unlocking. When the hand is released, the first spring 14 and the second spring 19 complete the reset. At the same time, when the two brackets 2 are unfolded and the implant locator body 1 is unfolded for operation, the central shaft 4 can be pinched and the threaded column 20 can be rotated. The vertical movement of the threaded column 20 when it rotates will drive the pressure ring 18 to squeeze the bracket 2, thereby locking the bracket 2 and preventing it from rotating freely and obstructing the operation.
