Patent number: 8668495Abstract: A ceramic and metallic dental abutment for use with a dental implant is disclosed. The abutment can generally include a body having a base region, a coronal region, and a transgingival region disposed between the base and coronal regions. The body regions can define a longitudinal axis. The base region can include an anti-rotational feature such that, when engaged with the dental implant, an anti-rotational connection exists. The coronal and transgingival regions can include a ceramic exterior surface. The abutment can further include a metal contact portion having an annular shape and positioned to engage the dental implant. The metal contact portion can include 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.Type: GrantFiled: March 26, 2013Date of Patent: March 11, 2014Assignee: Zimmer, Inc.Inventors: Ramiro Sanchez, Christopher M Gervais, Jeffrey Bassett
