Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a dental drill guide for oral implantation. Background Art

[0002] Dental implants are a method of restoring missing teeth that uses a lower structure implanted in bone tissue as a basis to support and retain the upper dental restoration. It uses artificial materials to make implants, which are surgically implanted into the tissue and obtain firm retention support from the bone tissue. The upper dental restoration is connected and supported by special devices and methods. Dental implants can achieve a restorative effect that is very similar to the function, structure, and aesthetic effect of natural teeth. They have become the preferred restoration method for more and more patients with missing teeth. A dental drill is generally used in the process of dental restoration implants. In the process of using a dental drill to implant teeth, a dental drill guide is required to guide the drill bit. However, due to the different sizes of missing teeth in different patients or in different edentulous areas of the same patient, the use of a guide with the same inner diameter specification will make the final implant position cannot be guaranteed to be completely consistent with the original design. In the existing patent application with application number CN202222240648.9, a dental drill guide for dental implants is proposed. Although the dental drill guide can be replaced according to needs, when replacing the dental drill guide, it is necessary to first remove the threaded sleeve from the first threaded rod, and then take the first threaded rod out from the first threaded hole and the second threaded hole. Only then can the dental drill guide be released. When installing the dental drill guide, the above steps need to be repeated, which makes the replacement steps of the dental drill guide more cumbersome and troublesome, and ultimately reduces the efficiency of replacing the dental drill guide. Therefore, it needs to be improved. Utility Model Content
