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.

임플란트 보철물은 유지방법에 따라 크게 나사 유지형 보철물(screw-retained prosthesis)과 시멘트 유지형 보철물(cement-retained prosthesis)로 나눌 수 있으며, 이들 장점을 고려하여 만든 나사-시멘트 유지형 보철물(SCRP: screw and cement retained implant prosthesis)이있다. 나사-시멘트 유지형 보철물은 임플란트 지대주와 상부 보철물 사이의 시멘트 층이 보철물 제작 과정에서 발생하는 여러 오차를 보상하여 수동적 적합을 얻을 수 있으며, 임상 및 기공 과정이 간단한 장점과 더불어 임플란트 보철의 유지 관리를 위해 필수적인 탈 부착(retrievability)이 가능하다. 본 증례에서는 완전 무치악 환자를 대상으로 상, 하악에 각각 9, 8개의 임플란트(US II, OSSTEM, Seoul, Korea)를 식립하고 나사 구멍이 순측으로 향하는 부위는 시멘트 유지형, 다른 부위는 나사-시멘트 유지형태를 사용하여 복합형태의 나사-시멘트 보철물(SCP: screw-cement prosthesis)을 제작하였으며 3년 간의 정기 검사에서 기능과 심미적으로 만족할 만한 결과를 얻어 이를 보고하고자 한다.
