Problems solved by technology

[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

Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] refer to figure 1 , the present invention provides an implant removal tool for taking out an implant 1, comprising a positioning protection sleeve 2 and a central bolt 4, the lower end of the positioning protection sleeve 2 is provided with a stepped hole capable of being inserted into the upper end surface of the implant 1 and The positioning boss 2a for positioning is provided with a central hole 2b with a large upper end and a smaller lower end on the upper surface of the positioning protective cover 2. The central hole 2b penetrates the positioning boss 2a downward, and the central bolt 4 is set in the center. In the hole 2b, and in the central hole 2b, a positioning step 2c for axial positioning of the central bolt is provided, and the positioning step is an inclined plane;

[0032] The two ends of the above-mentioned central bolt 4 all ex...

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 ...
