Title: SCREW-RETAINED ABUTMENT WITH OFF-AXIS FEATURE AND METHODS OF MAKING AND USING SAME
Abstract:
An abutment (14) is provided with a cavity (30) and a slot (28) in its sidewall (29) adapted to allow a driver (36) to access a screw (20) in the cavity (30) at an angle Θ relative to a longitudinal axis of the screw (20). The abutment (14) may include a screw seat (52) and may be connected to an implant (12) via a screw (20) in the screw seat (52). A prosthesis (16), which may include a driver access channel (18) that has a diameter less than the outer diameter of the drive portion or head (50) of the screw (20), may be placed over the abutment (14). Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.
