A novel medical prosthesis locking device, particularly for dental prostheses, which are to be fixed and yet easily removable for maintenance, etc. The locking device comprises a cylinder which is adapted to be embedded in the prosthesis and a plunger which is adapted to be slidably mounted in the cylinder so that when the plunger is in one position, the prosthesis may be inserted and placed in position within the mouth; and in another position the plunger engages an orifice in an immovable fixture in the mouth, e.g., abutment teeth crowned with short bar extensions containing holes properly aligned with and receptive of the locking end of the plunger of the locking device when the prosthesis is in position.
