Notes:
Although compositional gradients could be manufactured for the functionally gradedcoating that was showed to improve bonding strength between the coating and the substrate, thebiological efficacy of the graded coatings remained unclear. In this study, a functionally gradednanophase hydroxyapatite/bioglass (n-HA/bioglass) coating was prepared on a titanium (Ti)substrate for evaluating peri-implant osteogenesis in a canine model. The bone apposition andosteointegration of n-HA/bioglass coating were investigated at the interface compared with plasmaspraying HA (PS-HA) coating. The results showed that the coating degraded gradually over time butnot as fast as PS-HA coating did, and that more active bone apposition appeared on the n-HA/bioglasscoating. The in vivo study indicated that an early osteogenesis and osteointegration at the interfacecould be stimulated by the use of n-HA/bioglass coating in biological environment
