Abstract
결론
강도와 심미성을 겸비한 유전치부 전장관수복법을 모색할 목적으로, stainless steel과 복합
레진간의 효율적인 결합방법을 검토하였다. Stainless steel시편에 산화알루미늄분사법, 산화
알루미늄분사후 산부식법, 산화알루미늄분사후 양극산화법의 3가지 방법으로 금속표면을 처
리한 후, 금속-레진간의 접착방법으로써 Silicoater system, Superbond C ＆ B, Cesead
opaque primer를 적용하고 상부레진을 축조, 경화하였다. 3점 굽힘시험법을 이용하여 금속-
레진간의 결합강도를 측정하고, 레진-금속간의 파단면을 주사전자현미경으로 관찰하여 다음
과 같은 결과를 얻었다.
1. 금속면 처리방법중 EZ-Oxisor에 의한 양극산화처리법이, 접착방법중에는 Cesead
opaque primer를 적용한 것이 가장 높은 결합강도를 보였다.
2. Stainless steel 복합레진간의 결합력에는 금속의 표면처리방법이 접착방법보다 큰 영향
력을 보였으며, 파단면의 관찰결과, 결합력이 강한 군에서는 cohesive failure, 낮은 군들에서
는 adhesive failure가 나타났다.

For the purpose of searching for the restoration method yielding both strength and
esthetics for primary anterior teeth, various adhesion methods between stainless steel
and composite resin were evaluated. After stainless steel surface was pretreated with
alumina blasting, alumina blasting followed by acid-etching, and alumina blasting
followed by anodic oxidation respectively, silicoater system, Superbond C & B, and
Cesead opaque primer was applied as adhesive system, and Dentacolor resin was
built-up above them. Three primer was applied as adhesive system, and Dentacolor
resin was built-up above them. Three point bending test was performed under Universal
Testing Machine in order to measure the bond strengths, and bond-failed surfaces were
observed under scanning electron microscope.
The results were as follows :
1. Among three methods for pretreatment of metal surfaces, anodic oxidation group
with Ez-Oxisor revealed highest bond strengths. And Cesead opaque primer group
showed highest bond strengths among three kinds of adhesive system.
2. For bond strength, surface treatment seemed to have a greater influence than
adhesive system, and the features of cohesive failure in strongly bonded groups and
adhesive failure in loosely bonded groups were observed on bond-failed surfaces.
