Patent ID: 8668495

Claim:
A dental abutment configured for connection to a dental implant, comprising: a body having a base region, a coronal region, and a transgingival region disposed between the base and coronal regions, the body defining a longitudinal axis, the coronal and transgingival regions including a ceramic exterior surface; the base region including an anti-rotational feature such that, when engaged with the dental implant, an anti-rotational connection exists, wherein an external surface of the base region defines a notch having an annular shelf extending radially outwardly from the base region, an annular rim extending upwardly from the annular shelf, and an annular base wall extending radially outwardly from an upper end of the annular rim opposite the annular shelf; a central bore extending from a coronal end of the body to an apical end of the body; a screw seat positioned in the central bore between the coronal end and the apical end, and configured to engage a surface of a fastening screw, wherein the screw seat includes an inner diameter less than a diameter of the central bore at a location coronal to the screw seat; and a metal contact portion connected to the notch of the base region and configured to engage the dental implant, the metal contact portion having an annular shape and including a conical outer contact surface, disposed at an oblique angle with respect to the longitudinal axis, to match an angle of a chamfer of the dental implant.
