Abstract

The aim of this study was to compare and analyze wear resistance of acrylic resin tooth in denture opposing to different types of restoration materials. Also, it aimed to compare and analyze the hardness of three various types of resin artificial teeth when using five different types of denture detergents. In this study three types of artificial teeth were used. As ordinary acrylic resin tooth $Trubyte^{(R)}Biotone^{(R)}$ (Dentsply, U.S.A.) was used, and as high hardness resin tooth Endura $Posterio^{(R)}$ (Shofu, Japan) and Physio $Duracross^{(R)}$ (Nissin, Japan) were used. To compare wear resistance, gold alloy, dental porcelain, and composite resin were used as opposing restorations. In addition, with three types of resin tooth stated above, five types of denture detergents, which are $Yuhanrox^{(R)}$ (Yuhanclorox, Korea), $Polident^{(R)}$ (Yuhan Co., Korea), $Cidex^{(R)}OPA$ (Johnson & Johnson Medical Co., Korea), $Hexamedin^{(R)}$ (Bukwang Pharm Co., Korea) and Daihan sterile $water^{(R)}$ (Daihan Pharm Co., Korea) were used to compare and analyze the effects denture detergents have on the surface hardness. The results of this study were as follow : 1. When composite resin and dental porcelain were used as the opposing restorations, $Trubyte^{(R)}$ $Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ in ascending order showed decrease of cusp height with significant difference (p<0.05). 2. When gold alloy was used as opposing restoration, there was decrease in the cusp height in order of $Trubyte^{(R)}Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ and $Trubyte^{(R)}$ $Biotone^{(R)}$ especially showed significant decrease in high cusp height as compared to two other types of artificial tooth (p<0.05). 3. When composite resin, gold alloy and dental porcelain were used as opposing restorations, $Trubyte^{(R)}$ $Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ in order decreased greatly in weight and these three materials showed significant difference (p<0.05). 4. Comparing the experiment values, decrease in strength had significant difference in all resin artificial teeth before and after the denture detergents were used (p<0.05). 5. When resin artificial teeth were subsided in $Yuhanrox^{(R)}$, $Cidex^{(R)}OPA$, and $Hexamedin^{(R)}$, $Trubyte^{(R)}$ $Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ in order showed decrease in hardness, and $Trubyte^{(R)}$ $Biotone^{(R)}$ especially showed significant high decrease hardness as to other two types of artificial teeth (p<0.05). Therefore, Physio $Duracross^{(R)}$ seems to have superior wear resistance, and together with Endura $Posterio^{(R)}$, it presents excellent hardness as compared to $Trubyte^{(R)}$ $Biotone^{(R)}$. However, since this study is fragmentary, it should be given careful consideration and more study need to be done before making a definitive conclusion.

본 연구에서는 다양한 치과 수복재료에 대합되는 의치용 레진치의 마모저항성을 알아보기 위해 통상의 아크릴 릭 레진치인 $Trubyte^{(R)}$ $Biotone^{(R)}$ (Dentsply, U.S.A.)과 고강도 레진치인 Endura $Posterio^{(R)}$ (Shofu, Japan), Physio $Duracross^{(R)}$ (Nissin, Japan)를 수복재료인 금합금, 도재, 충전용 레진에 대합시켜 마모저항성을 비교 분석하였다. 또한 앞의 세 종류의 레진 인공치와 5종류의 의치세정제인 유한락스, 폴리덴트, 싸이덱스, 헥사메딘, 증류수를 사용하여 의치세정제 및 소독제가 경도에 미치는 영향을 비교 분석하여 다음과 같은 결과를 얻었다. 1. 대합되는 수복재료로 충전용 레진, 도재를 사용한 경우 $Trubyte^{(R)}$ $Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ 순으로 교두정 높이감소가 컸으며 세 재료간의 유의한 차이를 보였다 (p<0.05). 2. 대합되는 수복재료로 금합금을 사용한 경우 $Trubyte^{(R)}$ $Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ 순으로 교두정 높이 감소가 컸으며, 특히 $Trubyte^{(R)}$ $Biotone^{(R)}$ 이 다른 두 종류의 인공치보다 유의성 있게 높은 교두정 높이 감소를 보였다 (p<0.05). 3. 대합되는 수복재료로 충전용 레진, 금합금, 도재를 사용한 경우 모두 $Trubyte^{(R)}$ $Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ 순으로 무게 감소가 컸으며, 세 재료간의 유의한 차이를 보였다 (p<0.05). 4. 의치세정제에 따른 경도 감소는 실험 전과 후의 측정치를 비교했을 때 모든 레진 인공치에서 유의성 있는 차이 를 나타내었다 (p<0.05). 5. 유한락스, 싸이덱스, 헥사메딘에 담구었던 레진 인공치에 의한 경도감소는 $Trubyte^{(R)}$ $Biotone^{(R)}$, Endura $Posterio^{(R)}$, Physio $Duracross^{(R)}$ 순으로 높은 감소를 보였고, 특히 $Trubyte^{(R)}$ $Biotone^{(R)}$이 다른 두 종류의 인공치보다 유의성 있게 높은 경도 감소를 보였다 (p<0.05). 이상의 실험 결과 마모저항성 실험에서는 최근에 개발된 Physio $Duracross^{(R)}$가 다른 두 종류의 레진 인공치에 비해 세 종류의 대합되는 수복재료 모두에서 높은 마모저항성을 보였고 특히 $Trubyte^{(R)}$ $Biotone^{(R)}$에 비해 유의성 있게 높은 마모저항성을 보였다. 경도 실험에서는 Physio $Duracross^{(R)}$와 Endura $Posterio^{(R)}$$Trubyte^{(R)}$ $Biotone^{(R)}$에 비해 유의성 있게 낮은 경도감소를 보였고 (p<0.05), 폴리덴트, 증류수에서는 유의한 차이를 보이지 않았다. 따라서, Physio $Duracross^{(R)}$가 세 종류의 레진 인공치에 비해 우수한 마모저항성을 보인다고 볼 수 있고, Endura $Posterio^{(R)}$와 함께 $Trubyte^{(R)}$ $Biotone^{(R)}$에 비해서 우수한 경도를 보인다고 볼 수 있지만, 단편적인 실험 결과이므로, 아직은 신중하게 고려되어야 하고, 더 많은 연구가 필요하다고 사료된다.
