Abstract
This study was conducted to evaluate the tensile bond strength by bonding the dental bracket with Super-bond after treating the surface of dental Nickel-Chromium alloy with sandblasting, sandblasting & tin-plating, respectively, and tin-plating. 10 pieces of Nickel-Chromium alloys with brackets bonded with Super-bond without their surface treatment were sampled as a control group, 20 pieces of Nickel-Chromium alloy brackets bonded with Super-bond after treating them with sandblasting as group I, 20 pieces of Nickel-Chromium alloys tin-plated and bonded with Super-bond after sandblasting as group II, and then 20 pieces of alloys with brackets bonded with Super-bond after tin-plating as group III. The result of those examination and comparison is summarized as follows: 1. Group I showed the mean tensile bond strength of
본 연구에서는 치과용 니켈-크롬합금의 표면에 전처리없이 치과용 브라켓을 Super-bond로 접착한 대조군과 샌드블라스팅 및 tin-plating을 각각 혹은 병용으로 표면처리후 Super-bond로 접착한 실험각군의 인장접착강도, 브라켓 탈락양상 및 주사전자현미경 소견을 비교하여 임상적용 가능성을 알아보고자 하였으며 다음과 같은 결과를 얻었다. 1. 인장장접착강도는 니켈-크롬합금의 표면에 샌드블라스팅 처리후 Super-bond로 브라켓을 접착한 실험 I군이
