Representative histology images in the cancellous sites (2-mm and 1-mm gaps, line to line, and press fit) at 4 and 12 weeks for the a titanium alloy dowel coated with hydroxyapatite and b titanium alloy coated with plasma-sprayed titanium. Histology in the cancellous sites in the 4 implantation conditions (2-mm gap, 1-mm gap, line to line, and press fit) demonstrated the positive attributes of the HA coating in the 2- and 1-mm gap at 4 weeks with new woven bone ongrowth while the line to line to line and press fit conditions were similar. Cancellous histology at 12 weeks improved with time without the presence of any fibrous tissue and was similar for both groups
