차아삭제량의 증가로 임시합착은 필수적이 되었으며, 여러종류외 입시합착용 시멘트가

개발, 임상에 사용되고 있다.

본 연구는 임시합착시 사용된 임시합착용 시멘트가 영구합착시 결합력에 미치는 영향을

알아보기 위하여, 건전한 대구치 96개로 제작한 실험시편과 24개의 제3형 금합금시편을,

임시합착용 시멘트 3종과 영구합착용 시멘트 3종을 사용하여 합착한후 결합력을 비교 측

정한 결과 다음과 같은 결론을 얻었다.

1. 인산아연 시멘트에서는 Nogenol로 임시합착했던 군이 대조군보다 결합력이 다소 증

가하였고. Dycal과 Tempak에서는 대조군 보다 약간 감소되는 경향을 보였다.

2. 폴리카복실레이트시멘트에서는 대조군에서 결합력이 가장 높았고, Tempak, Nogenol,

Dycal외 순으로 결합력이 감소하는 경향을 보였다.

3. EBA 아연화 유지놀 시멘트에서는 Tempak으로 임시합착했던군이 대조군 보다 약간의

결합력 증가를 보였고, Nogenol과 Dycal에서는 약간 감소하는 경향을 보였다.

4. 영구합착용 시멘트의 결합력은 폴리카복실레이트 시멘트가 가장 높았고, 인산아연시

멘트, EBA아연화유지놀 시멘트의 순을 나타내었다.

The purpose of this experimental study is to research how temporary cementation

effects on the bond strength of permanent cementation.

For this experiment, I chose zinc phosphate, polycarboxylate and EBA ZOE cements

as permanent cements, and as temporary ones I selected Nogenol, Tempak and Dycal.

The ninetysix (96) specimens were prepared to measure the bond strength of

permanent cements after treated with temporary cements for one (1) week.

The tensile strength test was performed on an Instron Universal Test Machine with

cross head speed of 0.05cm/min. and the results were compared.

The results of this study were obtained no follows:

1. With zinc phosphate cement, there was a tendecy that the bond strength of the

group temporarily cemented with Nogenol increased, meanwhile it decreased a little

with Dycal and Tempak, more than that of the Control group.

2. With polycarboxylate cements, there was a tendency that the bond strength of

the Control group was the higher than that of experimental group and it decreased

in order of Tempak, Nogenol and Dycal.

3. With EBA ZOE cement, there was a tendency that the bond strength of the group

temporaily cemented with Tempak increased a little, meanwhile it decreased a little

with Nogenol and Dycal, more than that of the Control group.

4. In casc of permanent cements, the bond strength of polycarboxylate eements was

the highest and was followed in order of zinc phosphate cement and EBA ZOE cement.
