Abstract

The purpose of this study was to clarify the long-term endurance of crown retention cemented with resin-modified glass-ionomer cements (RMGI) by thermal cycling simulating the oral environment.<BR>In this study, two kinds of cement, Fuji lute (FL) and Vitremer luting cement (VL), were selected, and Super bond C & B (SB), a resin system cement, and Fuji I (F I), a traditional GI cement, were also tested as controls.<BR>All specimens were cemented to metal abutments with each cement, and put through the thermal cycling (4°C-60°C-37°C) test 0 times, 5, 000 times, 10, 000 times, and 15, 000 times, respectively.<BR>The result was as follows:<BR>1. The retention force of crowns cemented with FL showed little variation due to thermal cycling.<BR>2. The retention force of crowns cemented with VL increased due to thermal cycling.<BR>3. After 15, 000 times of thermal cycling, the values of FL and VL were similar to the value of SB, and these were about two times that of F I.
