摘要: Proponents of injection molding systems have claimed a number benefits over conventional press-pack dough systems. The aim this study was to evaluate recently developed (dry heat) procedure processing compared with utilizing three curing cycles. dimensional accuracy and stability acrylic resin bases produced by the two procedures were compared. Dimensional changes assessed period 4 months using an optical comparator. results demonstrate that baseplates exhibit less shrinkage than those procedures.
