AB In this work we studied the main surface characteristics together with the in vivoosseointegration of three Zr-Ti alloys with hydroxyapatite-zirconia-silver (HAP-ZrO2-Ag) coating layer. The main purpose was to provide a quantitative evaluation andinterpretation from micro to nano scale of the processes involved in the osseointegrationof the HAP-ZrO2-Ag coated Zr-Ti specimens in a pig model. The surface characteristicswere studied by scanning electron microscopy (SEM), energy dispersive X-rayspectroscopy (EDX), and X-ray diffraction (XRD). After the insertion of the implantsinto pig tibia, the osseointegration was investigated by means of biochemical analysis aswell as bone histomorphometric and computed tomography measurements. The results ofthis in vivo study sustains that the capacity of the Zr-Ti specimens coated with HAPZrO2-Ag to promote osteogenesis is significant during the first month after implantationas compared with the control, being influenced by the interactions between bone tissueand HAP-ZrO2-Ag surfaces, but also by the chemical composition of the alloys.
