“…Improved osseous integration may be obtained by the use of hydroxyapatite (HAp), b-tri calcium phosphate (b-TCP) and their composite coatings as nominally HAp to enhance the osteoconductivity of metallic implant (Thomas et al, 1987;Filiaggi, et al, 1991;Rivero et al, 1988). These coatings have been shown to promote osseointegration by stimulating bone growth onto the surface (Dey et al, 2011). Apart from calcium phosphate coating of metallic implants, extensive research has been initiated with bioglass as coatings for metallic implants because of their controlled surface reactivity and good bone bonding ability (Hench and Andersson, 1993;Ferraris et al, 1996).…”
