a Mercury porosimetry and the average pore diameter of the prepared implants. b EDX analysis of hybrid–zirconia surface showing peaks of zirconia, calcium, and phosphate. Ca/P ratio is 1.67. c XRD peaks of uncoated and bioactive implants showing characteristic peaks specific for tetragonal yttrium zirconium oxide crystal system represented by (101), (112), (200), and (211) and hybrid implants showing characteristic peaks specific for hexagonal HA crystal system. d Atomic force microscope of selective infiltration etching zirconia surface demonstrating subsurface porosities
