bioactive glass coated zirconia for dental implants: a review

Nowadays, zirconia has been favored greatly for dental implants; however its disadvantages such as poor mechanical properties and brittleness makes it unsuitable. on the other hand, bioactive glasses coating have been utilized on tougher substrates such as zirconia. bioactive glass coatings can decrease the healing time and hence accelerate the formation of the bond between bone and implant. hence, in this study, we introduce the novel zirconia/bioactive glass composites with high mechanical strength and bioactivity to achieve the ideal implant in dentistry. furthermore, a review of bioactive glass coatings (i.e., 45s5 and 58s) on zirconia as well as surface modification methods (i.e., sol-gel, laser cladding, plasma spraying, etc.) is provided.
