Description
Technical Field
The invention relates to an auxiliary tool for separating an abutment from a dental implant.
Background
The abutment separator is a device used for replacing the abutment during installation and debugging after the survival of the implant implantation and taking out the abutment when the abutment is loosened and does not need to be replaced when the abutment is repaired after the repair of the dental crown. As the abutment and the implant are matched by the Morse taper, once the abutment and the implant are matched, the implant and the abutment are difficult to separate.
At present, no instrument for separating the base station of which the implant is scientific, reasonable, simple and convenient and has no damage exists in the market, the base station on the implant is separated by adopting a hammer lateral knocking mode, but the mode has the following three fatal defects:
1. because the base station is matched with the implant, the mode that the hammer laterally strikes the base station can transfer the striking force to the implant, and the osseointegration of the implant is easy to damage;
2. the separation of the base stations cannot be ensured 100% by the way of laterally knocking the hammer;
3. the hammer is laterally knocked, so that loosening or breaking damage to the base station and the implant is easily caused, the base station is replaced or cannot be repaired, re-implantation is needed, and great trauma and pain are brought to a patient.
