摘要: The bases of occlusal rims and trial dentures should fit both the cast mouth accurately. retention shape dimension strips sheets grey pink shellac, filled cold cure acrylic resin wax were tested following moulding over stylised upper edentulous casts. thermoplastic materials softened a flame or in water bath. Specimens prepared with without folding along long axes strips. angles formed by strips, gap between palate baseplates casts linear measured after moulding, immersion at 37 45 degrees C 24 h room temperature. least angular change was shown unfolded moulded finger pressure an unwarmed cast, followed folded specimens fingers prewarmed cast. developed beneath shellac warmed smallest dimensional Thus, optimally manipulated exhibit less than modelling wax.
