Biological characterization of surface-treated dental implant materials in contact with mammalian host and bacterial cells: titanium versus zirconia.

ABSTRACT: Commercially pure titanium (cpTi) remains the material of choice for dental implants due to its surface properties which promote osseointegration. Recently, zirconia (ZrO₂) has been used as an alternative material due to its immunity to corrosion, mechanical strength, and biocompatibility. Previous in vitro studies evaluating oral bacterial attachment and mammalian host cell response to cpTi and ZrO₂ have yielded mixed results. Thus, the aim of the present study was to systematically evaluate the growth of early-colonizing oral bacteria and mammalian host cells on cpTi and ZrO₂ after three clinically-relevant surface treatments: polishing, acid-etching, or sandblasting. Polishing produced smooth surfaces (Sa: 0.08-0.22 μm) while acid-etching (Sa: 0.7
