dc.description.abstract[한글] 저자는 Silicoating이 수지접합 수복물의 결합력에 미치는 영향을 관찰하기 위해 금속의 종류를 달리하여 Rexillium Ⅲ, NNB, Pors-on 4, Degudent-U에 Silicoating을 한 후, 복합 레진계 세멘트인 MBAS으로 접착시켰다. 처리 방법에 따른 비교를 위하여 Rexillium Ⅲ는 전기화학적 식각과 Silicoating를 하었고, thermocycling군과 하지 않은 군을 비교하였다. 금속 시편은 Tensilon으로 접착인장강도를 측정하였고 금속-레진 계면의 미세구조를 알기 위하여 주사전자 현미경과 미세전자분석기, 그리고 2배 확대 관찰하여 다음과 같은 결론을 얻었다. 1. Rexillium Ⅲ와 Silicoating처리군이 전기화학적 식각처리군보다 접착인장강도의 증가를 보였고, 통계학적으로 유의차가 있었다 (P< 0.05). 2. Rexillium Ⅲ의 전기화학적 식각처리군에서 thermocycling시 접착인장강도의 통계학적인 유의차가 있었으나 (P< 0.05), Silicoating처리군에서는 유의차가 없었다(P> 0.05). 3. Silicoating처리시 접착 인장강도가NNB, Pors-on 4, Rexillium Ⅲ, Degudent-U순으로 감소하였다. 4. SEM 관찰시 전기화학적 식각에 비해 Silicoating은 gap이 없는 금속-레진 계면이 관찰되었다. 5. EPMA 관찰시 Silicoating은 전기화학적 식각보다 금속 - 레진 계면과 레진 세멘트부위에서 Si원소가 집중되어 나타났다. 6. 2배 확대 관찰시 Silicoating은 주로cohesive failure를, 전기화학적 식각처리시에는 adhesive failure를 보였다. [영문] This study investigated the effects of Silicoating procedure on the tensile bond strength of resin-bonded prostheses. The Rexillium Ⅲ specimens were treated with electrochemical etching and Silicoating procedure, followed by thermocycling and the NNB, Pors-on 4, and Degudent-U specimens were treated with Silicoating procedure. The specimens were debonded in tension with a Tensilon machine. Also, all specimens were observed with SEM, concentration of Si, elements was analysed with EPMA, and the mode of failure was recorded. The results of this study were obtained as follows: 1. In the Rexillium Ⅲ specimens, the tensile bond strength of the Silicoated specimens was higher than that of the electrochemically etched specimens, and significant differences were observed (P< 0.05). 2. The tensile bond strength of electrochemically etched Rexillium Ⅲ specimens, significant differences were observed between the thermocycled and nonthermocycled specimens (P<0.05), but no significant differences were observed in the Silicoated specimens (P> 0.05). 3. The tensile bond strength of the Silicoated specimens decreased NNB, Pors -on 4, Rexillium Ⅲ, and Degudent-U in that order named. 4. Unlike the electrochemically etched specimens, the Siliceated specimens stowed gap-free metal-resin interfaces with SEM. 5. Compared to the electrochemically etched specimens, the Silicoated specimens showed higher concentration of Si elements at the metal-resin interfaces and resin cement. 6. Photographic evaluation (Χ2) of the fractured sites revealed mainly cohesive failures with the Silicoated specimens, and adhesive failures with the electrochemically etched specimens.-
