Method for treating a screw-cement retained prosthesis and adjustment for a screw-cement retained prosthesis

Abstract

A method for treating a screw-cement retained prosthesis and an abutment are disclosed. The method for treating the screw-cement retained prosthesis comprises the steps of implanting a fixture in an alveolar bone; engaging an abutment including a first screw hole to the fixture using a screw; providing a prosthetic appliance including a second screw hole formed correspondingly to the first screw hole; and bonding the prosthetic appliance and the abutment by interposing dental cement between the abutment and the prosthetic appliance. The present invention includes advantages of a screw retained prosthesis and a cement retained prosthesis and can solve the problems of the screw and cement retained prostheses. Furthermore, in order to easily separate and remount the bonded abutment and prosthetic appliance from the fixture, an allowance groove, which may provide an allowance space, is formed in a receiving portion.
