Dental implant system

Abstract

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.

1 . A dental implant, comprising:
 a proximal end adapted to abut an abutment;   an interior bore extending distally form the proximal end;   a first anti-rotation cavity in the interior bore and comprising a first minor diameter; and   a second anti-rotation cavity in the interior bore and comprising a second minor diameter no greater than the first minor diameter.

         51 . A dental method, comprising:
 applying torque to a first internal anti-rotation feature of an implant to insert the implant deeper into the bone; and   subsequent to applying the torque to the first internal anti-rotation feature, engaging an abutment with a second internal anti-rotation feature of the implant.

         67 . An implant system, comprising:
 an implant comprising a first anti-rotational feature and a second anti-rotational feature,   a mount adapted to couple to the first anti-rotational feature to transfer torque to the implant to install the implant in a patient; and   an abutment adapted to couple to the second anti-rotational feature.
