The Effect of Different Fiber Concentrations on the Surface Roughness of Provisional Crown and Fixed Partial Denture Resin

ABSTRACT Objectives: The aim of this study was to investigate surface roughness in provisional crown acrylics, after polishing, reinforced with different concentrations of glass fibers. Methods: A total of 48 disk-shaped specimens were prepared using autopolymerizing acrylic resin. These specimens w...

Description
Summary:ABSTRACT Objectives: The aim of this study was to investigate surface roughness in provisional crown acrylics, after polishing, reinforced with different concentrations of glass fibers. Methods: A total of 48 disk-shaped specimens were prepared using autopolymerizing acrylic resin. These specimens were divided into four groups according to the level of glass fiber added: Group A (no fiber), Group B (0.5%), Group C (1%) and Group D (2%). After polishing the specimens, an average surface roughness (Ra) value was calculated using a profilometer from four randomly selected points on the surface. Results: A significant difference was determined among the surface roughness values of provisional crown resins to which different concentrations of fiber had been added (P
