N2 - New metastable beta Ti-based alloys arise as new perspective materials for dental implants due to adjusted chemical compositions that displays a reversible stress-induced martensitic transformation that leads to a superelastic effect (high recoverable strain) and a very significant reduction of the apparent elastic modulus. But it is still require increasing biological response that can achieve by surface modification. Plasma electrolytic oxidation (PEO) can be a perspective method for surface fynctionalisation. This research was dedicated to application of PEO in Ca(H2 PO2)2 solution for TIZr alloy surface treatment and investigation of newly formed coating structure and their biological properties. The alloy of the titanium-zirconium system (Zr60Nb21Ti19) was obtained from NanoPrime (Dębica, Poland). The anodic oxidation was performed under a constant current of 0.1 A cm−2 and up to final voltage of either 300 (TiZr-300), 400 (TiZr-400) and 450 (TiZr-450) V for 5 min. SEM, EDX and contact angle measurements were used for surface assessment and SBF test, cell culture and bacteriological assay—for biological evaluation. The use of plasma electrolytic oxidation to modify titanium-zirconium dental implants leads to the formation of an oxide layer and a mesoporous structure on their surface. Moreover, the peculiarities of morphology directly depend on electric voltage disturbance. Cultivation of cells on the surface of the samples showed a positive effect of adhesion of osteoblasts, compared with the control alloys, and confirmed that PEO at 450 V gives the best conditions for cell reproduction. Bacteriological examination showed that the experimental surface is less favorable for bacterial contamination compared to the control, but not significantly different from the voltage of the electric current. Therefore, this method of modification of titanium-zirconium alloys is promising for further research and opens new opportunities in medical practice.
