Novel non‐thermal plasma (NTP) technology has the potential to address the bonding issues of Y‐TZP and Ti surfaces. This study aims to chemically characterize and evaluate the surface energy (SE) of Y‐TZP and Ti surfaces after NTP application. Y‐TZP and Ti discs were treated with a hand‐held NTP device followed by SE evaluation. Spectra of Y‐TZP 3d and Ti 2p regions, survey scans, and quantification of the elements were performed via X‐ray photoelectron Spectroscopy (XPS) prior and after NTP. Separate Y‐TZP and Ti discs were NTP treated for contact angle readings using (10‐methacryloyloxydecyl dihydrogenphosphate) MDP primer. Significant augmentation of SE values was observed in all NTP treated groups. XPS detected a large increase in the O element fraction on both Y‐TZP and Ti surfaces. Reduction of contact angle reading was obtained when the MDP primer was placed on NTP treated Y‐TZP. Ti surface showed high SE before and after NTP application on Ti surfaces. NTP decreased C and increased O on both surfaces independently of application protocol. Wettability of MDP primer on Y‐TZP was significantly increased after NTP. The high polarity obtained on Y‐TZP and Ti surfaces after NTP applications appear promising to enhance bonds. © 2011 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2011.
