Abstract

Zirconia was proposed as an alternative material to titanium implant. Considering the condition of osseointegration and the stability of the implant, surface modifications of zirconia were attracting more and more attention. This study provides an overview of recent surface treatment technologies that have shown potential in augmenting the biological and osseointegration aspects of zirconia dental implants. These methods include non-thermal plasma treatment, laser texturing, TiO₂ and hydroxyapatite coatings, carbon and nitrogen implantation, and the use of bioactive molecules. we concluded that the surface modification of zirconia can enhance the osseointegration effect by inducing surface roughness, increasing the surface energy and potential, and introducing functional units to the surface. Moreover, dimensional changes in nanoscalestructure are not invariably dominant in osseointegration of all surface modification methods.
