A Biomimetic Titanate Nanoskeleton Coating on Zirconia Implants

Objectives: To develop and characterize a biomimetic titanate nanoskeleton coating on zirconia implants for enhanced bioactivity and osseointegration.
Methods: A uniform thin layer of titanium was deposited on standard-sized zirconia pieces by Denton Sputter (Denton Vacuum, USA). The biomimetic titanate nanoskeleton was developed by low-temperature alkaline hydrothermal treatment in 5M sodium hydroxide at 60 °C for 24 hours. The surface and cross-sectional structures were assessed by scanning electron microscopy (SEM). The topology was examined by atomic force microscopy (AFM).
Results: Uniform thin titanium with a thickness of 400 nm was successfully deposited on zirconia pieces. After alkaline hydrothermal treatment, the titanate nanoskeleton layer was formed on zirconia, which showed a nanoporous structure with interconnected beams and structs under SEM. The spongy 3D nanonetwork mimics the trabecular bone structure in the nanoscale and network of the cytoskeleton, which may promote cell attachment and interact to trigger cytoskeleton-related signaling pathways for osseointegration.
Conclusions: This study developed and characterized the biomimetic titanate nanoskeleton coating on zirconia.
