Abstract

Purpose: The purpose of this study was to evaluate the preload maintenance of the retaining screw when using anaerobic sealing agents in implant fixture and abutment components. Specifically, the study examines the effects of anaerobic sealing agents on different types of screws. Materials and methods: External hexagon implants made of titanium and anti-rotational abutments were used. Titanium abutment screws and ebony abutment screws from the same manufacturer were used. The experiment was divided into four groups (n = 10 in each group). In the control group, no sealing agent was used at the implant fixture and abutment screw interface. All abutment screws were tightened according to the manufacturer's recommended torque (30 N.cm). After 24 hours, the removal torque (detorque) of each screw was measured using a digital torque gauge device. The data were analyzed by two-way ANOVA test according to normality distribution satisfaction. Results: Looking at the results for each group, titanium screws and no treatment showed detorque values of 20.3 ± 1.6 N.cm. titanium screws and applied anaerobic sealing agent showed detorque values of 32.4 ± 6.7 N.cm. Ebony screws and no treatment showed detorque values of 20.2 ± 1.5 N.cm. ebony screws and applied anaerobic sealing agent showed detorque values of 30.4 ± 4.5 N.cm. Conclusion: The detorque value was higher in the case of using anaerobic sealing agents in both the titanium screw and ebony screw groups. But there was no difference between the two screws.

목적: 본 연구의 목적은 임플란트 지대주 나사에 혐기성 나사 고정제의 적용 유무와 나사 종류에 따른 풀림 토크 값의 차이를 평가하는 것이다. 재료 및 방법: 외부 육각형 임플란트 고정체를 사용하였고, 동일한 제조사의 지대주와 지대주 나사가 사용되었다. 지대주 나사는 두 종류로 티타늄 재질의 나사(티타늄 나사)와 텅스텐 카바이드 코팅된 나사(Ebony 나사)가 사용되었다. 티타늄 나사에 아무 처리하지 않은 군(TI군)과 티타늄 나사에 나사 고정제를 사용한 군(TI_AS군), Ebony 나사에 아무 처리하지 않은 군(EB군)과 Ebony 나사에 나사 고정제를 사용한 군(EB_AS군)에 대해 실험을 진행하였다. 총 4가지 군에서 각 10개씩의 임플란트 고정체-지대주 복합체가 사용되었다. 디지털 토크 측정 장비를 사용하여 풀림 토크 값을 측정한 뒤 통계 처리하여 각 군별 비교하였다. 정규성 분포를 만족하여 Two-way ANOVA test (α = .05)를 이용하여 통계 분석하였다. 결과: 각 군에 대한 결과를 살펴보면 TI 군은 20.3 ± 1.6 N.cm, TI_AS 군에서 32.4 ± 6.7 N.cm, EB 군은 20.2 ± 1.5 N.cm, EB_AS 군에서 30.4 ± 4.5 N.cm의 풀림 토크 값을 나타냈다. 결론: 혐기성 나사 고정제를 사용한 경우 티타늄 나사와 ebony 나사 모두에서 고정제를 사용하지 않은 경우 보다 풀림 토크 값이 높게 나타났다. 하지만 두 나사 군 간의 차이는 존재하지 않았다.
