초록
‘Implant Supracrestal Complex (ISC)’의 개념은 임플란트 보철물의 디자인 형태가 단기 임상 결과와 임플란트 주변 경·연조직의 장기 예후에 미치는 영향을 확인하는 방법으로 도입되었다. 임플란트-지대주 디자인과 접합부(junction) 및 위치와 같은 임플란트-보철물-지대주 복합 디자인 형태는 임플란트 주변 조직의 장기적인 유지에 중요한 영향을 미칠 수 있다. 본 증례에서는 임플란트 보철물 수복 후 만성적인 연조직 염증이 발생한 환자에게 오목한 맞춤형 지대주와 출현각이 30도를 이루는 보철물을 수복하였다. 새로운 보철물은 충분한 경·연조직 공간을 확보하고 적절한 연조직 폐쇄를 이룸에 따라 합병증이 개선되고 임플란트의 장기적인 안정성을 유지하는 것을 확인하였다.
Abstract
The concept of ‘Implant Supracrestal Complex (ISC)’ was introduced as a way to determine the impact of implant prosthetic design form on both short-term clinical outcomes and the long-term prognosis of bone and soft tissues around the implant. Implant-prosthesis-abutment complex design forms, such as implant-abutment design, junction, and location, can have important implications for the stable and healthy long-term maintenance of the tissues around the implant. In this case, a customized concave abutment and a prosthesis with an emergence angle of about 30 degrees were restored to a patient suffering from chronic soft tissue inflammation and pain after restoration of an implant prosthesis. It was confirmed that the new prosthesis improved complications by allowing sufficient bone and soft tissue space, achieved appropriate soft tissue sealing, and maintained the longterm stability of the implant
