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.
