Physicochemical Characterization and In Vivo Evaluation of Amorphous and Partially Crystalline Calcium Phosphate Coatings Fabricated on Ti-6Al-4V Implants by the Plasma Spray Method

Figure 6

Intimate contact between bone and implant surfaces was observed at 6 weeks (a) PSHA group and (c) ACP group. Woven bone formation at the healing chamber region, where no contact between bone and implant existed after device implantation, is depicted as well as its formation in close proximity to the implant surface. At 12 weeks, lamellar bone replacing woven bone was observed for both (b) PSHA and (d) ACP surfaces. The histomorphometric evaluation exhibited no significant differences between the two surfaces at both times in vivo (6 and 12 weeks) for (e) BIC (𝑃>0.86), and (f) BAFO (𝑃>0.75).
