Artificial denture teeth are subjected to wear from daily masticatory functions. This wear
affects the denture esthetics, functions and in turn results in patient discomfort. The purpose of
this study was to evaluate the wear resistance of nano composite fabricated artificial denture teeth
and conventional acrylic denture teeth reinforced with silica nano particles. A total number of
60 samples were used. Samples were divided into equal four groups (n=15). The first group was
fabricated from nano filled composite. The second and third groups were silica nanoparticles
modified acrylic denture teeth with two different concentrations 0.1% and 10% respectively. The
fourth group was conventional acrylic resin denture teeth and served as a control. The 2-body
wear testing was performed with a multi-modal ROBOTA chewing simulator. Wear was then
evaluated by the means of weight loss and surface roughness. The nano-composite group recorded
significantly higher wear resistance than conventional and silica modified acrylic resin groups. The
silica modified acrylic resin group with 0.1% concentration recorded a lower surface roughness
than any of the other groups. In conclusion; Nano-composite teeth can be used as artificial denture
teeth exhibiting significant higher wear resistance than conventional and silica modified artificial
acrylic teeth.
