Description

Technical Field

[0001] This utility model relates to the field of planting restoration technology, specifically to a planting bridge installation structure with anti-loosening features. Background Technology

[0002] Implant restoration is an advanced method of tooth restoration that involves implanting artificial implants into the site of missing teeth to restore their function and appearance. This technique not only improves patients' chewing function but also enhances facial aesthetics and boosts self-confidence.

[0003] In implant restoration technology, the implant bridge is a key structure connecting the implant to the superstructure, firmly fixing the prosthesis in the oral cavity, preventing loosening or dislodgement during chewing or speaking, and restoring normal occlusal function. The overall structure of the bridge evenly distributes chewing force across multiple implants, reducing the load on any single implant. Existing technology (Chinese patent application CN202120407557.2, filed on 2021-02-24) presents a digitally mountable implant bridge. During use, it includes the bridge body, prosthetic gingiva, porcelain crown, and implant. The prosthetic gingiva is positioned on the outside of the bridge body. The bridge body has multiple evenly distributed fixing holes along its length, with anti-rotation holes connected above these fixing holes. The anti-rotation holes have openings at their tops, and connecting screws are installed within the fixing holes. These connecting screws pass through the bridge body, effectively preventing relative displacement between the implant and the bridge body. The threaded engagement between the reinforcing rod and the mating hole further enhances the stability of the installation, thus standardizing the connection between the bridge body and the human oral cavity.

[0004] Although existing technologies can improve the stability of the installation, during use, the continuous vibration and alternating load generated by chewing in the mouth can counteract the bolt preload, causing micro-slippage of the threaded pair, eventually loosening, and affecting the stability of the implant bridge. Utility Model Content

[0005] The purpose of this invention is to provide an implant bridge installation structure with anti-loosening features, in order to solve the problem mentioned in the background art that the continuous vibration and alternating load generated during oral chewing can offset the bolt preload, leading to loosening of the threads and affecting the stability of the implant bridge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an implant bridge installation structure with anti-loosening features, comprising an implant bridge body, a denture being provided at the top of the implant bridge body, an implant assembly being provided at the bottom of the implant bridge body, and an installation component being provided on the inner wall of the implant bridge body.

Both the first external thread block and the first internal thread groove are provided with double threads, with the thread in the upper half being a fine thread and the thread in the lower half being a coarse thread.

[0010] Furthermore, a first magnetic block is fixedly connected to the top surface of the implant body, and a second magnetic block is fixedly connected to the bottom surface of the implant bridge body, and both the first magnetic block and the second magnetic block are circular in shape.

[0011] Furthermore, the installation assembly includes a fixing screw that is threaded to the inner wall of the implant body, and the outer wall of the fixing screw is provided with a second external thread block, and the size and structure of the second external thread block are consistent with those of the first internal thread groove.

[0012] Furthermore, multiple implant components and installation components are provided, and they are symmetrically distributed about the central axis of the implantation bridge body.

[0013] Furthermore, the anti-loosening component includes a locking block located on the top of the mounting component. The locking block is equipped with a spring made of nickel-titanium alloy. The top of the locking block is equipped with a cover screw. The outer wall of the cover screw is equipped with a third external thread block. The top surface of the planting bridge body is provided with a second internal thread groove whose internal dimensions and structure are consistent with the external dimensions and structure of the third external thread block.

[0014] Furthermore, the top surface of the fixing screw is provided with an inner hexagonal groove, and the bottom of the locking block is provided with an insert block whose external size structure is consistent with the internal size structure of the inner hexagonal groove.
