Abstract: A new dental implant with allows for repair of an existing root form implant after a traumatic event, which reduces or eliminates the need for further surgery. The implant uses an abutment which comprises a threaded spindle having an integrated taper, a plurality of segments around the axis of the spindle and a tapered nut threaded on the distal end of the spindle.

Abstract: A dental implant system is described which includes a root form for attaching to a patient's jaw bone and an abutment. The root form has a cavity. Furthermore, the abutment has an attachment portion, an insertion portion and an aperture. The insertion portion may be receivable within the cavity and form a taper lock therein. Finally, the aperture may pass through the abutment from the attachment portion to the insertion portion. In a preferred embodiment, the aperture is configured to receive a predetermined amount of hydraulic pressure to eject the abutment from the cavity, whereby the predetermined amount of hydraulic pressure overcomes the taper lock between the insertion portion of the abutment and the cavity.
