A method for treating a screw-cement retained prosthesis, an abutment and an implant are disclosed. The method for treating the screw-cement retained prosthesis, which relates to an internal implant, comprises the steps of providing an abutment comprising a joining projection, repositioning the joining projection to a joining groove formed in the upper portion of a fixture, engaging the abutment to the fixture by using a screw, providing a prosthetic appliance including a 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 all of the advantages of screw retained prostheses and cement retained prostheses and at the same time can solve the disadvantages thereof. Using a leading inclined surface formed in the joining projection, the abutment and prosthetic appliance are easily separated from and remounted to the fixture. |
