Laser Structured Dental Zirconium for Soft Tissue Cell Occupation-Importance of Wettability Modulation.

Various approaches are being pursued to physico-chemically modify the zirconia neck region of dental implants to improve the integration into the surrounding soft tissue. In this study, polished zirconia discs were laser microstructured with periodic cavities and convex waves. These zirconia samples were additionally activated by argon plasma using the kINPen09.
