Bioactive Glass Coated Zirconia for Dental Implants: a review
Kaiqiang Zhang, Quyet Van Le
Abstract
Nowadays zirconia, due to its interesting properties e.g. biocompatibility, strength, aesthetic, chemical and mechanical properties, has got lots of attention for dental implants. On the other hand, bioactive glasses have been used as coating 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 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.
