Abstract
A dental implant includes a generally cylindrical body, an interior bore, and a non-rotational feature. The generally cylindrical body has a main-central axis and is formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa. The generally cylindrical body has a proximal portion and an opposing distal portion for anchoring the dental implant in bone of a patient. The interior bore is formed in the generally cylindrical body and has (i) a bore-central axis and (ii) a threaded portion for receiving a screw that is configured to removable hold an abutment in engagement with the dental implant. The non-rotational feature is configured to engage the abutment in a non-rotational fashion.

1-94. (canceled)
A dental implant, comprising:
- a main body having a main-central axis, the main body having generally cylindrical upper portion and a tapered lower portion that leads to a small-diameter distal tip, the main body being formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa, the main body having a threaded surface extending from the generally cylindrical upper portion to the smaller-diameter distal tip for anchoring the dental implant in bone of a patient;
- an interior bore formed in the generally cylindrical upper portion and having (i) a bore-central axis and (ii) an interior threaded portion for receiving a screw configured to removable hold an abutment in engagement with the dental implant;
- and
- a non-rotational feature configured to engage the abutment in a non-rotational fashion.
A dental implant, comprising:
- a main body having a main-central axis, the main body having generally cylindrical upper portion and a tapered lower portion that leads to a small-diameter distal tip, the main body being formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa, the generally cylindrical upper portion has a first threaded portion and the tapered lower portion has a second threaded portion that blends into the first portion, the first and second threaded portions for anchoring the dental implant in bone of a patient, the second threaded portion having a peak-to-trough thread depth that is greater than a peak-to-trough thread depth of the first threaded portion;
- an interior bore formed in the generally cylindrical upper portion and having (i) a bore-central axis and (ii) an interior threaded portion for receiving a screw configured to removable hold an abutment in engagement with the dental implant;
- and
- a non-rotational feature configured to engage the abutment in a non-rotational fashion, the non-rotational feature being a socket formed in the interior bore.
