Abstract: The present invention relates to a one-piece dental implant having a threaded shaft which is tapered on one end and has a non-circular abutment on the other end, and a ball-shaped head mounted on said non-circular abutment. The inventive dental implants are advantageous in that they are of one-piece design, and, therefore, do not have multiple parts which can loosen over time. The present invention further relates to a keeper cap for use with the inventive dental implants, which is adapted to retain either O-ring-shaped inserts or plastic inserts. The inserts can be switched easily at any time without the need to remove the keeper cap from the denture or to form a new denture around new caps. The inventive dental implant and keeper cap make up a kit along with the O-ring-shaped inserts and the plastic inserts, which kit is useful in connection with the formation of fixed or removable prostheses.

Abstract: A sinus dental implant assembly stabilizer comprising(a) an elongated implant having an internal recess at one end,(b) an insert removably fitting into said recess, and having a head projecting laterally beyond said recess,(c) a washer capable of being removably held in fixed position by said implant and insert, and(d) a nut having an opening to fit over said implant of a size and internal configuration so as to be held in position on said implant, said nut holding said nut securely when said implant is being inserted into said nut.

Abstract: A cast dental implant abutment comprising a footpiece at the bottom end of the abutment, the footpiece having screw threads on the outer circumference thereof, and a castable cuff piece on the bottom thereof attached to the footpiece, the cuff piece on the top thereof having an indentation to accept the point of a screwdriver, the cuff piece capable of being severed at the top surface thereof at an angle other than 180.degree..

Abstract: A dental prostheses and method of mounting same comprises an implant having an upper neck portion, and a ferromagnetic casted coping comprising a precious metal alloy. A barrier cement layer between the coping and the neck for connecting same and a prosthetic member. A rare earth magnet is fixedly mounted in the prosthetic member at the gum facing side thereof and is coactive with the coping for retaining the prosthetic member in place. The coping is disposed at the crestal gum tissue level at the time of implantation.
