Patent number: 9220581Abstract: A dental implant device has an implant portion for being placed in a bore in bone. The implant portion has a coronal end portion and a porous metal portion. A metal coupling has a coronal end configured for connection to a denture support piece. The coupling also has an apical end integrally formed with the coronal end and engaging the porous metal portion. In one form, the coupling is attached to the porous metal portion in a threaded connection so that the coupling is removable from the porous portion without significantly damaging the porous metal portion sufficiently to re-engage another metal coupling.Type: GrantFiled: March 6, 2014Date of Patent: December 29, 2015Assignee: Zimmer Dental, Inc.Inventors: Michael Scott Collins, Jeffrey Bassett, Christopher M Gervais

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

Patent number: 8439680Abstract: A ceramic/metallic dental abutment for use with an implant, the abutment generally including a ceramic body portion having a base region, a transgingival region, and a supragingival region. The base region includes an anti-rotational implant interface, such as an external polygonal fitting, for engaging a cooperating internal polygonal fitting of an implant to prevent relative rotation between the abutment and the implant. The ceramic abutment body portion additionally includes a metal implant contact portion for contacting the implant and providing a load-bearing, metal-on-metal interface between the abutment and the implant.Type: GrantFiled: March 21, 2012Date of Patent: May 14, 2013Assignee: Zimmer Dental, Inc.Inventors: Ramiro Sanchez, Christopher M. Gervais, Jeffrey A. Bassett

Patent number: 8430668Abstract: Disclosed within is a dental restorative system including a dental fixture component having a longitudinal axis, a body portion, and an emergence profile portion adjacent to the body portion. The dental fixture component also has a tapered coronal portion adjacent to the emergence profile portion, with the tapered coronal portion having one end adjacent to the emergence profile portion and a terminal end with a non-frustoconical surface and a non-circular cross section. The emergence profile portion may include one or more concave surfaces. The dental fixture component may further include an interproximally sloping margin shoulder. Certain embodiments of the dental fixture component include threaded body portions. Alternative embodiments of the dental fixture component are also disclosed.Type: GrantFiled: April 27, 2006Date of Patent: April 30, 2013Assignee: Zimmer Dental, Inc.Inventors: Jeffrey A.

Publication number: 20090065376Abstract: A medical implant package including a vial and a cap connected by a hinge. The vial includes a cavity for housing at least a portion of a dental implant. To access the implant, the cap is rotated about the hinge from a closed position to an open position. The cap defines a second cavity, separate from the vial cavity, sized to contain a healing screw. In one embodiment, the cap includes two portions connected by a living hinge which define the second cavity. The two cap portions, when moved relative to each other via the living hinge, permit access to the healing screw. In an alternative embodiment, the cap includes two retention members sized and configured to grip the healing screw. To remove the healing screw from the cap, the two retention members are displaced apart from each other by engaging them with a wedge extending from the vial.Type: ApplicationFiled: November 17, 2008Publication date: March 12, 2009Inventors: Ryan M.
