Abstract
The goal of this study was to compare the adhesion of
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.
There was a significant difference in the adhesion of
The CAD/CAM procedure for fabricating complete dentures showed promising potential for reducing the adherence of

<p>The goal of this study was to compare the adhesion of <italic>Candida albicans</italic>
to the surfaces of CAD/CAM and conventionally fabricated complete denture bases.</p>
</sec>
<sec><title>MATERIALS AND METHODS</title>
<p>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. <italic>Candida</italic>
colonization was performed on all the specimens using four <italic>Candida albicans</italic>
isolates. The difference in <italic>Candida albicans</italic>
adhesion on the discs was evaluated. The number of adherent yeast cells was calculated by the colony-forming units (CFU) and by Fluorescence microscopy.</p>
</sec>
<sec><title>RESULTS</title>
<p>There was a significant difference in the adhesion of <italic>Candida albicans</italic>
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 <italic>Candida albicans</italic>
than did the denture bases created with the conventional procedure (<italic>P</italic>
<.05).</p>
</sec>
<sec><title>CONCLUSION</title>
<p>The CAD/CAM procedure for fabricating complete dentures showed promising potential for reducing the adherence of <italic>Candida</italic>
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.</p>

<abstract><sec><title>PURPOSE</title>
<p>The goal of this study was to compare the adhesion of <italic>Candida albicans</italic>
to the surfaces of CAD/CAM and conventionally fabricated complete denture bases.</p>
</sec>
<sec><title>MATERIALS AND METHODS</title>
<p>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. <italic>Candida</italic>
colonization was performed on all the specimens using four <italic>Candida albicans</italic>
isolates. The difference in <italic>Candida albicans</italic>
adhesion on the discs was evaluated. The number of adherent yeast cells was calculated by the colony-forming units (CFU) and by Fluorescence microscopy.</p>
</sec>
<sec><title>RESULTS</title>
<p>There was a significant difference in the adhesion of <italic>Candida albicans</italic>
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 <italic>Candida albicans</italic>
than did the denture bases created with the conventional procedure (<italic>P</italic>
<.05).</p>
</sec>
<sec><title>CONCLUSION</title>
<p>The CAD/CAM procedure for fabricating complete dentures showed promising potential for reducing the adherence of <italic>Candida</italic>
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.</p>
