Method for treating a screw-cement retained prosthesis and adjustment for a screw-cement retained prosthesis
First Claim
1. A method for treating a screw-cement retained prosthesis, comprising the steps of:
- repositioning and engaging an abutment including a first screw hole to a fixture using a screw;
providing a prosthetic appliance having 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.

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.

8. A method for treating a screw-cement retained prosthesis, comprising the steps of:
-
providing an implant wherein an abutment including a first screw hole is engaged with a fixture by a screw and a prosthetic appliance is bonded to the abutment;
forming a second screw hole, which corresponds to the first screw hole, on the prosthetic appliance; and
separating the prosthetic appliance and abutment from the fixture by loosening the screw through the first and the second screw holes. - View Dependent Claims (9, 10)

11. An abutment for a screw-cement retained prosthesis, comprising:
-
a screw hole formed upward and downward through an abutment body; and
a receiving portion for receiving a joining projection formed on an upper end of a fixture;
wherein the receiving portion comprises a sticking groove stuck to an upper end of the joining projection and an allowance groove providing an allowance space, which causes the joining projection to be easily separated from and joined to the sticking groove. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
