Implant removal tool and removal method

Abstract

The invention provides an implant removal tool, which is used for removing an implant or a bolt in the implant. The implant removal tool comprises a positioning protective jacket and a central bolt sheathed in the positioning protective jacket, wherein the central bolt can be replaced with a twist drill or a reverse screw tap. In addition, the invention further provides an implant failure resolution method, which comprises the following steps: disinfection, positioning, drilling, tapping, taking out the bolt, fixing and taking out the implant. According to the implant removal tool and the implant removal method, the implant is conveniently and rapidly taken out, the pain and loss of patients can be maximally reduced, the losses of manpower, material resources, financial resources and time can be avoided, the doctor-patient disputes can be decreased, and the dental implant technology is also favorably developed.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to an implant extraction tool and extraction method. Background technique [0002] In the prior art, there are roughly three methods for taking out failed implants: 1. Use a ring-shaped bone drill with a diameter larger than the implant to directly cut off the bone tissue around the implant and take it out. The disadvantage is that the trauma is relatively large and the bone tissue is damaged The damage range is large and irreversible; 2. Use a twist drill to guide the hole and then take it out with a reverse tap. Due to the random and irregular cross-section of the fractured implant, the positioning is lacking in accuracy, and if the osseointegration force is large, Insufficient anti-rotation force of the reverse tap. 3. Use a wrench that matches the anti-rotation hexagonal, octagonal or plum blossom groove inside the implant to take it out. The disadvantage is that it is difficult ...
