The screw that secures an abutment onto a dental implant.
Biofunctional dental implant
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.

An implant comprising two internal anti-rotational features. One anti-rotational feature is adapted to engage a driving tool, while the other anti-rotational feature is adapted to engage an abutment. An implant abutment system is provided with an angled abutment adapted to mate with one of the anti-rotational features. A second, straight abutment is adapted to engage with the other anti-rotational feature. An abutment is provided with resilient fingers to interface with the implant and provide tactile and audible feedback indicating when the abutment is properly seated. An abutment screw extends through the abutment and engages the implant bore distal of the stem of the abutment. The abutment screw limits axial movement of the abutment relative to the implant. A driving tool comprising one of at least retention structure and visual alignment indicia is provided to facilitate screwing the implant into a patient's bone.
