Abstract: 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.

Abstract: 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.

Abstract: A dental implant can comprise a shaft defining a longitudinal axis and having an apical end, a coronal end, and an exterior surface. A portion of the exterior surface can include a porous material. The dental implant can comprise at least one thread, including a non-porous material, having an interior surface and a bone-engaging surface. The interior surface can engage and wind around the exterior surface of the shaft and the bone-engaging surface can extend outwardly from the exterior surface of the shaft. The shaft can include one or more channels configured to communicate a flowable material, stored within the shaft, to the exterior surface. Each channel can include an opening at the exterior surface to release the flowable material. At least one channel can extend between a cavity of the shaft and the exterior surface and can optionally be angled toward the apical end.

Abstract: A patient-specific porous metal prosthesis and a method for manufacturing the same are provided. The orthopaedic prosthesis may be metallic to provide adequate strength and stability. Also, the orthopaedic prosthesis may be porous to promote bone ingrowth.

Abstract: A patient-specific bone implant has a porous body with a core material covered with tantalum. It is made with unique outer dimensions selected to match a specific patient.

Abstract: 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.

Abstract: An expendable bone implant has a first member with a coronal end portion configured for supporting a prosthesis. A second member is at least partially porous, engages the first member, and is configured to expand outwardly upon a longitudinal force being applied to at least one of the first and second members. This anchors the implant in bone before mastication forces are applied to the implant.

Abstract: Dental implants made at least in part of a highly porous biomaterial such as porous tantalum for enhancing the osseointegration of the dental implant into surrounding bone. For example, there is provided a dental implant which includes a core formed of with a head portion having an abutment interface and a stem portion extending from the head portion. A porous tantalum sleeve is disposed about the stem portion and occupies a substantial portion of the implant/bone interface of the implant. After implantation of the implant, bone tissue may osseointegrate into the porous tantalum sleeve to anchor the implant in position within the surrounding bone. Other embodiments of implants are provided, each implant including at least a portion thereof formed of porous tantalum for improved osseointegration.

Abstract: Disclosed within is a dental restorative system including an impression coping with a body portion having a first end, a second end, and an internal chamber having non-frustoconical side walls. The body portion also has a facial aspect and a lingual aspect and the distance between the first end and second end on the facial aspect is greater than the distance between the first end and second end on the lingual aspect. The first end of the impression coping may include an opening and an interproximal, continuous slope. Certain embodiments of the impression coping include means for engaging an abutment or implant, located on the internal chamber. Other embodiments include external flange portions for retention of the coping in impression material. Alternative embodiments of the impression coping are also disclosed.

Abstract: A bone implant surgery system is used for simulating a dental surgical procedure having a display that shows placing a simulated bone implant at a simulated implant site on a living body by using a simulated surgical tool holding the simulated bone implant. At least one hand-held haptic device is used to control the surgical tool and at least one controller is specifically configured to cause movement of the surgical tool on the display based on motions of the haptic device and to cause haptic feedback to a user holding the haptic device depending on the position of the surgical tool on the display. A user may then review and evaluate the results of the surgical simulation.
