Abstract:

The aim of this study was to quantify the attachment of Candida Albicans C.albicans to conventionally fabricated poly methyl methacrylate, PMMA, CADCAM milled and 3D printed denture resin bases and compare changes while the denture resin bases were subjected to thermal simulated aging processes. The advent of Computer-Aided Design and Computer-Aided ManufacturingCADCAM milled and 3D printed resins has streamlined much of complex denture fabrication processes. The interaction between C.albicans an opportunistic fungal pathogen, and new CADCAM milled or 3D printed denture resin base surfaces are largely unknown. C.albicans is a major etiological factor of denture stomatitis in which symptoms include inflammation, swelling, and petechial hemorrhages. Stomatitis, if untreated, can lead to ill-fitting dentures, oral erythema, and dysphagia, ultimately diminishing the quality of life of patients.
