Bone support type upper jaw rear long implant implantation guide seat based on three-dimensional printing technology

Abstract

The invention relates to the technical field of medical instruments, in particular to a bone support type upper jaw rear long implant implantation guide seat based on a three-dimensional printing technology. The guide seat comprises an upper jaw bone in-place fixing plate which is fixedly attached to the upper jaw bone, an implantation guide ring part which is arranged to be of a round sleeve structure, is coaxial with an implantation drill needle, is located below the upper jaw bone and directly faces the implantation position of the upper jaw bone, a guide piece which is coaxially and detachably inserted into the implantation guide ring part and is provided with a positioning hole which is through in the axial direction, allows the implantation drill needle to penetrate through and is matched with the penetrating implantation drill needle, and a pair of connecting rods which are integrally connected with the upper jaw bone in-place fixing plate and the implantation guide ring part, wherein the upper jaw bone in-place fixing plate, the implantation guide ring part, the guide piece and the pair of connecting rods are integrally formed. By adopting the scheme, the implantation operation can be simpler, more accurate and quicker.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone-supported maxillary posterior long implant planting guide seat. Background technique [0002] Dental implants have gradually become an important means of restoring missing teeth. With the development of dental implant technology, many patients who could not receive dental implant due to insufficient alveolar bone volume can also receive dental implant, and achieved good restoration results. Conventional dental implants in the maxillary molar area require implants with a length of at least 6-12 mm, and the process of implantation and hole preparation should avoid penetrating the maxillary sinus floor (to avoid the risk of maxillary sinus infection and implant failure). Disuse resorption and gasification of the maxillary sinus floor decrease, and the remaining alveolar bone in the maxillary molar area after tooth loss often presents a significant shortage, making it...

AI Technical Summary

Problems solved by technology

We believe that this solution has the following problems: 1. Other incisions are required for the placement of surgical navigation and registration brackets, resulting in secondary damage; 2. Loose navigation and positioning brackets lead to errors between the design position and the actual position; 3. The overall time of navigation surgery is long, resulting in Postoperative swelling, infection, and increased intraoperative bleeding

[0005] There are also a few scholars and patents who have reported the technology of using digital design and planting guide to guide the planting operation. However, due to the limitations of design and material of the guide plate, this kind of technology is only suitable for conventional planting operations. For zygomatic implantation, the previous guide plate had defects such as insufficient strength, excessive thickness, difficulty in ensuring accurate positioning and depth control, which led to poor accuracy of implant guidance, and could not be truly applied in clinical practice.
