Abstract :

This study aimed to evaluate the surface changes and wettability of PMMA as a prosthetic material after different durations of argon plasma-jet surface treatment. Four Poly Methyl Methacrylate (PMMA) discs were machined and smoothed with silicon polishing discs. The surface changes were evaluated in a control group and in groups with different plasma-jet exposure application times [30-60-120 seconds (s)]. The average contact angle (CA) measurements and surface changes were recorded via a tensiometer and scanning electron microscope (SEM) respectively. According to the results, the argon plasma-jet surface treatment markedly affects the wettability properties. With an increase in the application time, a remarkable reduction in CA and surface changes were observed. Within the limitation of this study it can be concluded that the argon plasma-jet could enhance the wetting performance and adhesive capability of PMMA.
