ABSTRACT:
A biofunctional dental implant wherein a crown portion is connected to a root portion without the use of the conventional short screws, or the like. A flexible abutment projects upwardly from the root portion, and the crown portion is positioned in surrounding engagement with the flexible abutment. A threaded abutment post is advanced through the flexible abutment and into receipt by the root portion. The advancement of the abutment post through the flexible abutment generates an outward pushing force for causing a plurality of flexible splines of the abutment to bend outwardly and into engagement with an elastomeric cap of the crown portion for holding the crown portion atop the root portion. In one preferred embodiment, a replacement crown portion is detachably connected to an existing root portion by way of a removable abutment screw so as to enable a broken or worn crown portion to be removed and replaced without the need for a new surgery.
