Abstract

The osseointegration of Ti6Al7Nb implants obtained by selective laser melting, both uncoated and coated with SiO2+TiO2 or hydroxyapatite, has been analysed. The mineralization of uncoated implants, although relatively high after one month, decreases with time showing a minimum after three months, but recovering the starting value after 6 months. A high degree of mineralized bone for coated samples has been shown after one month, then little increasing with time. The best osseointegration was evidenced for implants coated with hydroxyapatite. The reasons for the observed behavior are discussed..
