Representative histology images in the cortical sites at 12 weeks (top row × 1.25, middle × 10, bottom × 20 objectives) for the a titanium alloy dowel coated with hydroxyapatite and b titanium alloy coated with plasma-sprayed titanium. Bone remodeling without any adverse reactions was noted for both groups. The HA coating remained intact. The failure during push-out testing can be seen in the low magnification image for the Ti plasma (b)
