Abstract

The invention discloses a failed implant taking-out device, belongs to the technical field of dental implantation, aims to provide the failed implant taking-out device, and solves the problems that anexisting tool is low in broken implant taking-out efficiency and causes large wounds. The failed implant taking-out device comprises a first reverse screw tap, a second reverse screw tap, a third reverse screw tap and a torque wrench, wherein a first tap body part is arranged at the end of the first reverse screw tap, reverse teeth are arranged on the first tap body part, a second tap body part is arranged at the end of the second reverse screw tap, and reverse teeth are arranged on the second tap body part; and a third tap body part is arranged at the end of the third reverse screw tap, reverse teeth are arranged on the third tap body part, the taper of the second tap body part is larger than that of the third tap body part, and the taper of the second tap body part is smaller than thatof the first tap body part. The invention is suitable for the failed implant taking-out device.

Description

technical field [0001] The invention belongs to the technical field of dental implants, and in particular relates to a device for taking out failed implants. Background technique [0002] In the prior art, when the implant fails or is damaged, the method of taking out the failed implant is usually to use a circular bone extraction 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 , a large range of damage to bone tissue, and irreversible damage. [0003] It can be seen that the efficiency of taking out the fractured implant with existing tools is very low, and at the same time, it causes a lot of trauma to the patient. Therefore, it is of great significance to develop an implant extraction tool that is easy to operate and can avoid patient discomfort. Contents of the invention [0004] The object of the present invention is to provide a device for t...
