  • Patent number: 6126445
    Abstract: Dental implant abutment systems, related devices, and implantology processes and techniques. The abutment systems include a base that is adapted to mount in nonrotating fashion on any desired dental implant, root form or blade, from any supplier, together with a fixation screw which secures the base to the implant. A core, to which an abutment is cast in customized shape and form as desired is attached to the base preferably in threaded fashion and secured with an appropriate antirotational mechanism. Alternatively, the core and abutment may be formed using CAM processes. Such abutment systems, unlike prevalent conventional systems, do not require a central access bore in the core or abutment components, and they occupy significantly less volume than conventional abutments.
