Abstract

Conventional techniques or digital computer-aided design and computer-aided manufacturing (CAD/CAM) by milling or three-dimensional (3D) printing are currently used for denture processing. CAD/CAM-milled discs are pre polymerised by the manufacturer under heat and pressure, which minimises their porosity and residual monomers; therefore, they exhibit improved mechanical properties and reduced bacterial adhesion. In contrast, resins for denture bases manufactured by 3D printing are polymerised by light, resulting in increased residual monomer concentrations and porosity. Hygiene and the disinfection of removable prostheses is essential to remove biofilm, increase longevity and maintain good oral health. Stomatitis has been reported to be the main cause of superinfection in patients with prostheses, especially infection with Candida spp. Poor denture hygiene has not only been associated with problems in the oral cavity but also with a 2.4 times higher risk of severe pneumonia.1 The ideal hygiene product or system would achieve an optimal level of disinfection of the dentures, be nontoxic and avoid alterations in the physical and mechanical properties, such as colour and dimension. In addition, it should be affordable. Among the mechanical methods for cleaning dentures, brushing is the most used because of its simplicity, effectiveness and low cost.
