MTT assay (a) and ALP assay (b) of Ti6Al4V, HA/800TiO2/Ti6Al4V, and MgO/SiO2-HA/800TiO2/Ti6Al4V after 3, 7, and 11 days. Osteoblast cell viability is enhanced by in the presence of MgO and SiO2 and plasma-sprayed HA coatings compared to Ti6Al4V control (n = 3, *p < 0.05). Osteoblast cell differentiation is enhanced at day 11 in the presence of MgO and SiO2 and plasma-sprayed HA coatings compared to Ti6Al4V control (n = 3, *p < 0.05).
