Abstract

The purpose of this study was to evaluate the fitness of 4 kinds of resin record base materials. The record base materials used on the edentulous cast in this study were Triad VLC resin (Dentsply International Inc., U.S.A.), custom tray resin (Kerr Ltd,. U.S.A), heat-cure resin (Dentimex Co., Holland), and self-cure resin (Dentimex Co.,Holland). The gap width between record base and cast were measured in the ridge crest and midpalatal area with microhardness tester. @ES The results obtained were as follows : @EN 1. Among the 4 kinds of record base, heat-cure Vertex fitted best on the cast. Triad and Fomatray fitted better than self-cure Vertex. Self-cure Vertex had the poorest. fit. 2. The quality of the fit of the record base varied at different locations on the cast. The record base fit better in the ridge crest than midpalatal area.
3. In the midpalatal area, there’s no significant difference in the fit of Fomatray, Triad and heat-cure Vertex. They all fit better than self-cure Vertex. 4. In the ridge crest, heat-cure Vertex fit better than any other record base.
