임플란트 최신 재료 - 티타늄 지르코늄 합금 Titanium Zirconium alloy

소개

주제는 티타늄 지르코늄 얼로이를 재료로한 임플란트 픽스쳐에 관한 내용입니다.
티타늄과 지르코늄은 주기율표에서 같은 족에 위치하고 있어 그 성질이 비슷한 부분이 많으며 안정적이고 균질한 알파상의 alloy를 형성합니다.
기존에 사용되던 cpTi에 비해 더 향상된 물리적 특성과 생체 적합성을 갖고 있어
좁은 치조제를 가지거나 수직적으로 임플란트 식립공간이 부족할 때에 조금더 강한 결합을 도모할 수 있습니다.

본문내용

티타늄과 지르코늄은 주기율표에서 같은 족에 위치하고 있어 그 성질이 비슷한 부분이 많으며 안정적이고 균질한 알파상의 alloy를 형성합니다.

이번 발표에서 살펴볼 제품은 스트라우만에서 2008년 개발한 록솔리드입니다.
13-17%의 지르코늄을 함유한 티타늄 과 지르코늄의 이원 합금으로, 기존에 사용되던 cpTi에 비해 더 향상된 물리적 특성과 생체 적합성을 갖고 있어
좁은 치조제를 가지거나 수직적으로 임플란트 식립공간이 부족할 때에 조금더 강한 결합을 도모하기 위해 개발된 제품입니다.
