Abstract

Purpose: The purpose of this in vitro study was to compare the marginal adaptation of a ceramic-pressed-to-metal restoration with traditional metal-ceramic restoration. Materials and methods: Duplicating the prepared resin tooth, 20 metal dies were fabricated. Twenty metal copings of 2 groups which were metal ceramic restoration and pressed to metal restoration were fabricated. The marginal opening of each coping was measured with Microscope (BX 60M-36E $41D^{(R)}$: Olympus, Japan). After porcelain build-up, the marginal opening of metal ceramic restoration and pressed to metal restoration ($PoM^{(R)}$: Ivoclar vivadent., Liechtenstein) were also evaluated in the same method. The measurements were analyzed using Wilcoxon Signed Ranks test and Mann-Whitney U test. Results: Within the limits of this study, the results were as follows. 1. Metal-ceramic restorations in coping state ($64.93{\pm}12.48\;{\mu}m$) in compared with Metal ceramic restorations after porcelain build-up ($63.43{\pm}12.86\;{\mu}m$) had no significant difference in marginal adaptation. 2. Pressed-metal-ceramic restorations in coping state ($50.00{\pm}12.28\;{\mu}m$) in compared with Pressed metal ceramic restorations after porcelain build-up ($56.72{\pm}13.80\;{\mu}m$) had no significant difference in marginal adaptation. 3. Metal-ceramic restorations in compared Pressed-metal-ceramic restorations had no significant difference in marginal adaptation. Conclusion: Pressed-metal-ceramic restorations have the advantage of being technically less change through using of the lost-wax technique and this allows for the convenience of a full-contour ceramic wax-up as opposed to the more technique-sensitive layering method. Pressed-metal-ceramic restorations may be considered in clinic on the basis of the result of this study and the advantage of this system.

연구 목적: 본 연구의 목적은 전통적인 금속 도재관과 열-가압을 이용한 금속-도재관의 변연 적합도를 비교하는 것이다. 연구 재료 및 방법: 상악 제1소구치 레진 치아를 교합면 2.0 mm, 협, 설면과 인접면을 1.0 mm 두께로 삭제하였으며, 변연 형태는 chamfer margin으로 그리고 축면 경사는 6도 taper로 삭제하였다. 삭제한 레진치를 복제하여 금속 다이 20개를 제작하였고, 이 금속 다이를 인상 채득하여 작업을 위한 석고 다이를 제작하였다. 금속 도재관과 $PoM^{(R)}$ 시스템 (Ivoclar vivadent., Liechtenstein)의 두 그룹으로 나누어 금속 코핑을 각각 10개씩 총 20개를 제작하였으며, 광학 현미경을 이용하여 변연 간격을 측정하였다. 도재 축성 후, 위와 동일한 방법으로 변연 간격을 측정하였다. 통계 처리는 Wilcoxon Signed Ranks test와 Mann Whitney U test를 이용하여 분석하였다. 결과: 본 연구의 결과는 다음과 같다. 1. 금속 도재관은 코핑 상태 ($64.93{\pm}12.48\;{\mu}m$)와 도재 축성 후 ($63.43{\pm}12.86\;{\mu}m$)의 변연 간격에 유의성 있는 차이를 보이지 않았다. 2. $PoM^{(R)}$ 시스템은 코핑 상태 ($50.00{\pm}12.28\;{\mu}m$)와도재축성후($56.72{\pm}13.80\;{\mu}m$)의 변연 간격에 유의성 있는 차이를 보이지 않았다. 3. 금속 도재관과 $PoM^{(R)}$ 시스템 변연 간격은 유의성 있는 차이를 보이지 않았다. 결론: $PoM^{(R)}$시스템은 왁스 소결법을 이용해 변화가 적은 기술적인 이점이 있으며, 세밀한 기술을 요구하는 축성 방법과는 대조적으로 왁스 성형으로 도재의 완전한 형태를 만들 수 있는 편리함을 제공하는 장점을 가진다. 본 연구 결과와 이런 장점을 토대로 앞으로 임상적 사용을 고려해 볼 수 있을 것으로 사료된다.
