Abstract
The goal of this study was to compare the adhesion of
to the surfaces of CAD/CAM and conventionally fabricated complete denture bases.
Twenty discs of acrylic resin poly (methyl methacrylate) were fabricated with CAD/CAM and conventional procedures (heat-polymerized acrylic resin). The specimens were divided into two groups: 10 discs were fabricated using the CAD/CAM procedure (Wieland Digital Denture Ivoclar Vivadent), and 10 discs were fabricated using a conventional flasking and pressure-pack technique.
colonization was performed on all the specimens using four
isolates. The difference in
adhesion on the discs was evaluated. The number of adherent yeast cells was calculated by the colony-forming units (CFU) and by Fluorescence microscopy.
There was a significant difference in the adhesion of
to the complete denture bases created with CAD/CAM and the adhesion to those created with the conventional procedure. The CAD/CAM denture bases exhibited less adhesion of
than did the denture bases created with the conventional procedure (
<.05).
The CAD/CAM procedure for fabricating complete dentures showed promising potential for reducing the adherence of
to the denture base surface. Clinical Implications. Complete dentures made with the CAD/CAM procedure might decrease the incidence of denture stomatitis compared with conventional dentures.
