Abstract: A dental implant assembly includes an implant for osseointegration in alveolar bone, an abutment removably attached to the implant for supporting a tooth prosthesis, and a screw received through an axial bore in the abutment and engaging a threaded bore in the implant. The implant includes an annular shoulder and a plurality of splines spaced from one another to define slots therebetween and disposed circumferentially about the opening of the threaded bore. The abutment includes an annular end face in engagement with the annular shoulder of the implant. A cylindrical recess is disposed radially inwardly of the annular end face and receives the splines of the implant therewithin. The cylindrical recess communicates with the axial bore. A plurality of circumferentially spaced axially extending splines defining slots therebetween are disposed within the cylindrical recess and are interleaved with the splines of the implant.

Abstract: An endosseous dental implant system comprising an artificial root and a canted coronal section. Interposed between the artificial root and the canted coronal section is an intermediate post having a locking formation adjacent both the coronal section and the artificial root. A floating screw is captured inside the intermediate post and permits the intermediate post to be secured to the artificial root independently from the coronal section. The coronal section can be secured on the intermediate post with a free screw.

Abstract: A sterile delivery system for a dental implant comprising a vial and cap with a detachable driver. The dental implant is secured to the driver by a screw. Once the implant has been secured in the jaw of a patient, the driver is removed and the screw is replaced on the implant root portion as a healing screw. In this fashion, the total number of parts required, and the number of parts contacting the implant are reduced, thus reducing the possibility of infection and simplifying the number of components in the sterile delivery system.

Abstract: A spinal disk implant is implanted between vertebrae of the human spine following discectomy. The implant comprises a solid body having four sides and a pair of spaced-apart, opposed bases. The four sides include spaced-apart, opposed anterior and posterior faces, and a pair of spaced-apart, opposed transverse faces. Each transverse face has an anterior platform adjacent to the anterior face. The anterior platform is spaced apart from the opposed anterior platform by a maximum anterior platform spacing. A posterior ledge is oriented at an insertion angle relative to an opposed posterior ledge of the opposed transverse face. At least one of the posterior ledges has a pattern of serrations. There is a ridge on at least one of the transverse faces, positioned between the anterior platform and the posterior ledge and extending in the direction perpendicular to the bases. The top of the ridge is spaced apart from the opposed transverse face by an amount greater than the anterior platform spacing.

Abstract: A spinal disk implant comprises a solid body having four faces arranged to define a right-rectangular solid body and two faces that define the ends of the solid body. The faces that define the right-rectangular body include two opposed side faces and two opposed transverse faces. The transverse faces have a central region with three-dimensional features thereon and an anterior platform region lying along an anterior margin of the transverse faces. The faces defining the ends of the solid body include a convexly curved anterior face and a posterior face. The solid body is made of a biocompatible synthetic material. A kit that may be used by a surgeon includes an implant and an implant delivery tool dimensioned to releasably hold the implant.

Abstract: An endosseous dental implant system comprising an artificial root and a coronal portion. Interposed between the artificial root and the coronal portion is an adjustable internal jam nut for providing a selected preload when the coronal portion is mounted in the artificial root.

Abstract: An o-ring attachment system with opposed convex circumferential surfaces for removable dentures to be attached to a natural or an implanted fixed root system. The o-ring attachment system can be screwed into an implanted root using a manipulating means interposed between o-ring abutment and an attachment screw. In connection therewith, a tool is provided for implanting the o-ring attachment system, the tool having a captured toroidal spring for gripping the attachment system.
