Abstract

|
Implant prostheses were classified into screw-retained prosthesis and cement-retained prosthesis by their method of retaining, and there is screw and cement retained implant prosthesis (SCRP) which has been made reflecting the strengths of these two. The advantages of the SCRP technique are easy retrievability and passive fit of implant prostheses. However, the occlusal screw holes of implant prostheses can be thought as a disadvantage with respect to esthetics and occlusion. Inappropriately positioned implants also limited the use of the SCRP technique. The present study is reporting about the case where nine implants (US II, OSSTEM, Seoul, Korea) were placed in maxilla and eight in mandible respectively in fully edentulous patients. Then, the cement-retained prosthesis was applied for the part in which the screw hole positioned improperly, and screw-retained prosthesis for properly positioned implants so that the combined screw-cement prosthesis has been produced where the satisfying result has shown in both function and esthetics. Three-year follow-up has been done for the patient.
