일반적으로 즉시 부하가 가능한 ISQ 값은 얼마인가? | Meredith4가 임플란트의 안정성을 평가하기 위해 개발한 공진주파수 분석법은 객관적이고 비침습적인 방법으로 인정받고 있다.9 공진주파수 분석은 임플란트의 초기고정을 공진주파수를 이용하여 측정하는 방식으로 ISQ라는 임플란트 안정성 지수로 나타내며 ISQ 값이 보통 65이상이면 즉시 부하(Immediate loading)가 가능한 것으로 보고되고 있다.29 공진주파수 값이 감소하는 경우 고정 정도의 감소와 연관이 있어 임플란트 실패의 가능성이 높다고 판단할 수 있다. | |
임플란트 안정성 중 일차안정성은 어떤 요인들에 영향을 받는가? | 임플란트 안정성은 임플란트가 주변골과 접촉됨으로써 얻을 수 있는 일차안정성과 골치유와 골형성결과에 의한 이차안정성으로 구분할 수 있는데 일차안정성은 임플란트 식립 부위의 골질과 골량, 외과적 술식, 임플란트의 길이, 직경, 형태, 식립방법, 디자인 및 표면 거칠기의 결과 등에 영향을 받는다. 4,6,7최근에는 임플란트의 안정성을 위해 임플란트 디자인과 임플란트 표면처리의 개선이 이루어져 왔으나 이러한 개선에도 불구하고, 환자에게 식립된 임플란트의 안정성을 판단하여 하중 시기를 결정하는 것은 매우 어렵다. | |
공진주파수 분석법은 평가한 정도를 어떤 값으로 나타내는가? | 그래서 공진주파수 측정은 임플란트 성공과 실패를 예측하기 위해 많이 사용되고 있다. 초기에는 RFA 값을 Hz로 표시하였으나 OsstellTM mentor로 상품화된 뒤 ISQ란 수치로 1 - 100까지 표시하게 되어 있다. 공진 주파수측정으로 임플란트 식립시 초기안정성과 치유기간 동안의 안정성을 평가할 수 있어 실패가능성이 높은 임플란트를 조기에 발견하고 임플란트 보철후의 안정성을 평가하는 것이 어느 정도 가능하게 되었다. |
