Easily-removing implant device and screwing-out tool thereof

Abstract

The invention discloses an easily-removing implant device and a screwing-out tool thereof. The easily-removing implant device comprises an implant, a base station and a central bolt; the easily-removing implant device is characterized in that the implant comprises a gum-penetrating neck part and a head part, wherein a thread is formed on the outer surface of the head part, at least two spiral self-tapping grooves are also formed in the outer surface of the head part, a connecting hole coaxial with the implant is formed in the implant, the connecting hole comprises a tapered hole, an anti-rotation hole, an implant taking-out section and a blind threaded hole, which are sequentially connected coaxially, the base station comprises a dental crown connecting section and an implant connecting section, the implant connecting section comprises a conical table and an anti-rotation column, a stepped hole matched with the central bolt is formed in the base station, and the central bolt penetrates through the stepped hole to be connected with the blind threaded hole, so that the base station and the implant are fixed integrally. According to the easily-removing implant device, the implant taking-out section with a reverse thread is additionally arranged in the implant, the problem that a part of the implant, which is remained in dentale due to fracture of the implant, is difficult to take out is solved, and the easily-removing implant device has the advantages of simple structure, strong practicability, and the like.

Description

technical field

[0001] The invention relates to the field of oral medical instruments, in particular to an implant device which is easy to take out and a screw-out tool thereof. Background technique

[0002] With the continuous development of oral implant technology, the technology of "artificial dental implant" has gradually matured and stabilized. Artificial dental implants are to first place a highly biocompatible titanium artificial tooth root into the alveolar for fixation and suture, and after a few months, after the artificial tooth root is firmly connected to the bone in the alveolar, the follow-up denture installation is carried out. Since the artificial tooth root is directly connected to the bone, it can provide better supporting force. Popular for chewing harder foods.

[0003] Generally speaking, implants are divided into embedded implants and non-embedded implants. The disadvantage of implantable implants is that it is necessary to wait for the implant to be...
