title: A comparison of physical characteristics of six hard denture reline materials.
abstract: Six rigid autopolymerizing acrylic resins were examined to determine and compare the cost per reline, the curing temperatures, the setting times, and the porosity of each material. The cost per reline ranged from $0.63 to $1.55. Three product groups had significantly different mean setting times, and two groups had significantly different mean setting temperatures. SEM cross-sections of each product revealed an apparently porous-free solid mass of acrylic resin, which in two products was overlayed by a thin porous surface layer. The physical characteristics of any one product did not indicate clinical superiority.
