An Experimental Study on the Tissue Structure around the Hydroxylapatite-coated Implants Loaded for 6 Months

Abstract

To clarify whether or not direct bone interface of two-stage plasma-sprayed hydroxylapatite-coated implant could be achieved by nontapping insertion and this interface could also be maintained following functional loading, clinical and histologic studies were performed using monkeys. All hydroxylapatite-coated implants were clinically neither mobile nor rotated at all. Peri-implant gingiva seemed to be clinically healthy. Direct bone interface was observed and well-maintained after 6 months of loading.
