Heat-cured acrylic resin specimens were polished using either conventional laboratory
polishing, sandpaper, or three commercial chairside kits. The surface roughness
of the polished specimens was measured with a contact profilometer. Scanning
electron microscopy was used to obtain microphotographs of the polished surfaces.
Laboratory polishing produced the smoothest surfaces in all cases, while sandpaper
application produced the roughest. Use of the chairside polishing kits resulted in
significantly rougher surfaces compared to those produced by laboratory polishing.
Nonetheless, polishing of trimmed denture bases using chairside polishing kits
is an effective alternative procedure for cases in which the laboratory procedure
is not applicable. Int J Prosthodont 2013;26:79–81. doi: 10.11607/ijp.3157
