Histomorphometric Analysis of a Half Hydroxyapatite-Coated Implant in Humans: A Pilot Study
Iamoni, Francesco / Rasperini, Giulio / Trisi, Paolo / Simion, Massimo
The aim of this study was to compare the characteristics of the bone-to-implant interface of hydroxyapatite-coated and non-coated commercially pure titanium threaded implants after different periods of healing in humans. To eliminate possible variations of the results from differences in bone quality and in surgical techniques used in the different test and control sites, only one half of each implant was coated with hydroxyapatite. The coated portions of the implants showed a tendency toward a higher percentage of direct bone-to-implant contact at each period of healing that was observed, although the small number of specimens does not allow definitive conclusions to be made.
