Abstract

In conventional bar- and clip-retained overdentures, all errors during impression making and cast fabrication result in non-passive fit of bars. SFI bar is prefabricated and assembled in the patient's mouth without the use of soldering, laser welding or conventional bonding techniques, thus reducing stress transmission to, bone loss around the implants and leading to fewer errors and lower costs. A clinical case will be presented below to demonstrate the use of the SFI Bar (Stress Free on Implant Bar) to restore an severe atrophy edentulous maxilla. In this case, no lateral stress could be applied to the implants due to the telescopic design of the bar joints. However, periodic recall check is necessary and long-term clinical results are required.

전통적인 바와 클립 유지형 피개의치의 경우, 인상채득 및 기공과정에서 오차가 생길 수 있어 바가 nonpassive fit하게 제작될 수 있다. 최근에 나온 기성품 바 어태치먼트 시스템인 SFI-Bar (Stress Free on Implant Bar) system (Cendres+Metaux, Biel/Bienne, Switzerland)은 튜브바로 연결하여 조립하는 방식이므로 밀링방식이나 캐스팅방식에서 겪을 수 있는 작업상의 많은 어려움과 긴 작업 시간의 단점을 보완 할 수 있고, 임플란트 주위골에 가해지는 스트레스도 줄여줄 수 있다. 본 증례에서는 골흡수가 심한 상악 무치악 환자에게 최근에 나온 stress free implant bar인 SFI-Bar system을 사용한 피개 의치로 수복하였다. SFI Bar를 이용한 피개의치 제작시 수동적 적합을 얻을 수 있어 임플란트에 스트레스를 덜 가하는 장점을 얻을 수 있을 것으로 생각한다. 추후 정기적인 검사를 통해 장기적인 결과에 대한 평가가 필요하리라 사료된다.
