Description

Technical Field

[0001] This utility model relates to the field of dental implantation, specifically to a multifunctional transfer rod for dental implantation. This transfer rod achieves the core functions of precise transfer of the implant abutment position and intraoral scanning positioning, while also having a function of protecting the bone integration period. Background Technology

[0002] In dental implant restoration, it is crucial to accurately transfer the three-dimensional position information of the intraoral implant abutment to a model or digital system. This is usually achieved through a transfer rod, but the traditional dental implant procedure has the following drawbacks:

[0003] Traditional dental implant procedures involve numerous components, requiring the preparation and management of healing caps, transfer caps, scanning rods, and other parts. When impressions are needed for prosthesis fabrication or intraoral scanning, the healing cap must be removed before installing a dedicated transfer cap or scanning rod. This multi-step process increases patient discomfort, chairside time, and the risk of cross-infection. Furthermore, repeated disassembly and reassembly can introduce errors. Traditional healing caps, with their simple structure relying primarily on a single screw for retention, may loosen or fall off under chewing forces, affecting osseointegration stability and easily accumulating food debris and fostering bacterial growth. Therefore, a multifunctional transfer rod for dental implants is proposed. Utility Model Content

[0004] The purpose of this invention is to address the problems in the current traditional implant restoration process, such as numerous components, cumbersome operation steps (requiring disassembly and replacement), directional requirements for the installation of transfer / scanning components, insufficient stability of healing caps, and susceptibility to bacterial growth. This invention provides a multifunctional transfer rod for dental implants to solve the problems mentioned in the background section.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The present invention is as follows: a multifunctional transfer rod for dental implants, comprising a rod base, the bottom of which has an installation groove for mounting on an implant abutment. The lower part of the installation groove is cylindrical, and the upper part is frustoconical. An installation bolt is fixedly connected inside the installation groove and is fixedly connected to the frustoconical bottom of the installation groove. The inner surface of the installation groove fits against the top of the implant abutment. The interior of the installation groove has a smooth surface. An operating nut is fixedly connected to the top of the rod base, and the top of the operating nut has a standard interface hole.

[0007] As a preferred technical solution of this utility model, the material of the rod base is medical-grade titanium alloy.

[0008] As a preferred technical solution of this utility model, the operating nut is made of wear-resistant resin.

[0009] As a preferred technical solution of this utility model, the rod base is heat-fused to the operating nut.

[0010] As a preferred technical solution of this utility model, the surface of the rod base is provided with an antibacterial coating, and the antibacterial coating contains active factors.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. With the set rod base and standard interface hole, the rod base can be installed and fixed to the implant base once. It does not need to be disassembled during the entire implantation and repair cycle (including the bone integration period and the impression / scanning stage). The matching impression rod or scanning rod assembly can be directly connected through the interface to accurately complete the implant position transfer or intraoral scanning positioning. This completely avoids the cumbersome steps of disassembling the healing cap and installing the transfer cap / scanning rod in the traditional process, and significantly reduces the time spent in the clinic, patient discomfort, operation error and infection risk.

[0013] 2. With the installation slot and installation bolts, the smooth frustum + cylinder composite structure inside the installation slot makes it easy to install without the need for specific circumferential angle alignment. Simply put the rod base into the top of the planting base and tighten the installation bolts to complete the firm fixation. The operation is extremely quick and easy, effectively resisting the rotation or displacement caused by chewing force and avoiding the accumulation of food residue and the growth of bacteria.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0021] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] 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.

[0023] 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.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this embodiment proposes a multifunctional transfer rod for dental implants, including a rod base 1. The bottom of the rod base 1 has an installation groove 2 for mounting on an implant abutment. The lower part of the installation groove 2 is cylindrical, and the upper part is frustum-shaped. The composite structure of the frustum and cylinder eliminates the need for specific circumferential angle alignment during installation. The frustum-shaped design guides the rod base 1 to quickly fit onto the top of the implant abutment, and the fitted inner surface helps to disperse stress. An installation bolt 3 is fixedly connected inside the installation groove 2, and the installation bolt 3 is fixedly connected to the frustum-shaped bottom of the installation groove 2. The inner surface of the installation groove 2 fits against the top of the implant abutment. The interior of the installation groove 2 has a smooth surface. An operating nut 4 is fixedly connected to the top of the rod base 1 for easy clamping operation. The top of the operating nut 4 has a standard interface hole 5, which is designed with standard size and structure for direct connection when the transfer rod is fixed to the implant abutment. In use, the mounting slot 2 of the rod base 1 is directly inserted into the top of the planting platform. Then, the mounting bolt 3 is tightened by tightening the operating nut 4 with a tool to secure it. During the mold removal stage, the fixing screw of the matching mold removal transfer rod is screwed into the standard interface hole 5. During the intraoral scanning stage, the positioning structure of the matching scanning rod is inserted into or engaged with the standard interface hole 5. With this design, when it is necessary to transfer the position or scan, there is no need to touch or disassemble the transfer rod. The operation can be completed by directly connecting the corresponding components inside the mouth, which simplifies the process to the greatest extent and ensures accuracy.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the base 1 of the rod is made of medical-grade titanium alloy. In use, medical-grade titanium alloy provides excellent biocompatibility, corrosion resistance, and mechanical strength.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the operating nut 4 is made of wear-resistant resin. In use, the wear-resistant resin is lightweight and has a smooth surface, meeting the requirements of the oral cavity environment.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the rod base 1 and the operating nut 4 are heat-fused together. In use, the heat-fused connection ensures the connection strength and sealing between the rod base 1 and the operating nut 4.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the surface of the rod base 1 is provided with an antibacterial coating, which contains active factors. During use, the active factors in the antibacterial coating are continuously released to inhibit bacterial growth and reduce the risk of peri-implantitis.

[0029] Specifically, when using the multifunctional transfer rod intended for dental implants: After the implant surgery, the mounting slot 2 of the rod base 1 is directly inserted into the top of the implant abutment, and the mounting bolts 3 are tightened to secure it. The transfer rod covers the abutment, providing protection and maintaining stability (e.g., Figure 1 and Figure 5 As shown), the transfer rod remains in the mouth during the bone integration period, and its antibacterial coating continues to work, protecting the abutment area (such as...). Figure 5 As shown), when osseointegration is complete and a prosthesis needs to be fabricated, there is no need to disassemble the transfer rod. Simply screw the retention screw of the matching impression rod into the standard interface hole 5, and directly transfer the impression inside the mouth. During intraoral scanning, connect the positioning component of the matching scanning rod to the standard interface hole 5, and directly perform optical scanning inside the mouth (e.g., Figure 1 As shown in the image, after the final restoration is fabricated, this multi-functional transfer bar needs to be removed before it is inserted, and the final restorative abutment and crown can be replaced.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
