Histomorphometry of Bone Apposition Around Three Types of Endosseous Dental Implants
Weinlaender, Michael / Kenney, Ernest Barrie / Lekovic, Voja / Beumer III, John / Moy, Peter K. / Lewis, Steven
Three different types of commercially available dental implants (Nobelpharma, IMZ, and Integral) were implanted in the edentulous mandibles of seven adult mongrel dogs. Twenty-one implants were harvested with block sections after 12 weeks and embedded in polymethyl methacrylate resin. Undecalcified sections were prepared with the sectioning-grinding technique. The percentage of bone contacting the implant surface was measured with a self-designed histomorphometry method using a millimeter grid in a stereomicroscope. The results demonstrated a significantly higher percentage of bone along the hydroxyapatite-coated implant than that seen with the titanium-surfaced implant types.
