임플란트의 파절의 발생 빈도는? | 1 단일 임플란트로 지지되는 구치부 보철물은 임플란트에 큰 응력을 발생시키고 임플란트 파절 가능성을 높인다. 임플란트의 파절은 1,000개 중에서 2회의 발생 빈도로 발생하는 것으로 보고되고 있다.2 임플란트 제조회사에서는 임플란트-지대주 연결부를 다양한 설계로 생산하지만, 임플란트의 연결부와 관련된 파절 등 합병증에 대한 믿을만한 자료를 제공하지 않는 실정이다. | |
임플란트 시스템에서 임플란트의 강도와 안정성을 결정하는 요소는? | 모든 임플란트 시스템에서 임플란트-지대주 연결부의 기계 공학적 완벽성은 임플란트의 강도와 안정성을 결정하는 중요한 요소이다.4-6 임플란트 연결부의 설계는 평평한 접촉 연결부(butt joint)와 마찰 결합 연결부(friction fit joint)의 두 가지로 대별된다. | |
마찰 결합 연결부가 의미하는 것은? | 7 첫번째 유형은 외측 육각형 연결부로 평면들이 서로 피동적으로 접촉하고 임플란트와 지대주 사이에 작은 공간이 존재한다. 두번째 유형은 내측 원추형 연결부를 갖고 마찰 결합 계면을 갖고 있다. 이 두 가지 유형은 외측 연결형과 내측 연결형으로 크게 분류된다. |
