Threaded hydroxylapatite-coated implants of commercially pure (CP) titanium were inserted in the rabbit tibial metaphysis. Uncoated CP titanium screw implants inserted in the contralateral leg served as controls. After 6 weeks and 1 year postinsertion, the semiloaded implants were histomorphometrically analyzed. While not significant, there was more direct bony contact with the hydroxylapatite-coated implants after 6 weeks of follow-up. One year after insertion, there was significantly more direct bone-to-implant contact with the uncoated CP titanium controls.
将商业纯钛（CP）制成的带螺纹羟基磷灰石涂层植入物插入兔胫骨近端干骺端。插入对侧腿的未涂层CP钛螺钉植入物作为对照。植入后6周和1年，对半负载植入物进行组织形态计量学分析。随访6周后，与羟基磷灰石涂层植入物有更多直接骨接触，虽不显著。植入1年后，未涂层CP钛对照物与植入物之间的直接骨接触显著更多。
