Microarc Oxidation Coatings Doped with a Low Proportion of Yttrium Enhance the Osseointegration of Titanium Implants through the BMP/Smad Pathway.

ABSTRACT: Adding metal ions is a promising strategy to enhance the biological performance of titanium implants. In this study, we aimed to explore the effects of yttrium on the osseointegration of titanium implants. First, a series of yttrium-doped titanium surfaces were fabricated via microarc oxidation (MAO) by incorporating yttrium acetate into the electrolyte, and then the surface characteristics of different substrates were evaluated. Subsequently, the cellular behaviors of different coatings were assessed, and the osteointegration effects were examined using a rat model. Finally, high-throughput sequencing was employed to elucidate the underlying mechanisms of the yttrium-doped MAO coatings. As the results indicated, the proportion of yttrium in the coatings increased as the concentration of y
