Description

Planting three-edged drill convenient to change drill bit

Technical Field

The utility model relates to the technical field of dentistry, in particular to a planting triangular drill convenient for replacing a drill bit.

Background

The dental implant is to implant an implant into the upper and lower jawbones of a tooth-missing part of a human body by means of a surgical operation, and install a device for repairing a dental prosthesis at the upper part of the implant after healing of an operation wound, and generally comprises a bone level implant and a soft tissue level implant. In the operation of implanting implant in the oral cavity of a patient, an implant guide plate corresponding to the teeth in the oral cavity of the patient needs to be manufactured before operation, and a doctor can be helped to determine the implantation position of implant nails in the operation through the implant guide plate.

When the implant is implanted, holes are needed to be taken by means of different types of drills. Drilling is a key step in the denture implantation process, and key tools used by each large implantation system are a positioning drill, a reamer and a forming drill. In the existing dental implant technology, the drill bits of different types are usually required to be replaced to perform hole taking treatment, but the drill bits in life are often of an integrated structure, and the drill bits do not have a good replacement effect, and the drill bits are required to be replaced after being disassembled during use.
