Abstract

Purpose: Glass ceramic spray coating (GCSC) represents an innovative surface treatment technology that can be employed to create glass ceramics on zirconia surfaces, thereby enhancing the physical and chemical properties of zirconia. Nonthermal plasma has been demonstrated to effectively increase surface energy and clean the surface. Consequently, GCSC combined with plasma treatment represents a promising surface treatment method for dental implants, although further investigation is required to assess its biological responses. Methods: The experiment was divided into seven groups: titanium alloy (Ti), untreated zirconia (NT), zirconia treated with air abrasion (AB), zirconia treated with hydrofluoric etching after GCSC (GE), and zirconia groups that were further treated with nonthermal plasma (NTPL, ABPL, GEPL). The surface analyses included SEM morphology images, roughness measurements, and wettability assessment, while the biological responses examined were cell attachment, survival, and toxicity. Results: The experimental results demonstrated that the GE and GEPL groups exhibited the highest roughness. GCSC-treated group demonstrated the better wettability, and the wettability of the plasma-treated groups exhibited a significant improvement (p < 0.05). Notably, all groups exhibited no evidence of cytotoxicity, and the ABPL and GEPL groups demonstrated the most favorable cell adhesion. Conclusions: The combination of GCSC and nonthermal plasma can impart a rough and hydrophilic surface to zirconia with excellent bioactivity, which is anticipated to become a viable surface treatment method for zirconia implants.
