Abstract
Two different groups of hydroxyapatite (HA) coated and uncoated porous titanium implants, 250-350 μm and 500-700 μm diameter beads, were press-fitted into femoral canine cancellous bone. After 12wks, the dogs were killed and histomorphometric backscattered electron microscopy studies were carried out. Comparing HA coated versus uncoated implants in the 250-350 μm bead diameter group, the percentage of bone (P = 0.01) and bone index (P = 0.01) were higher in the HA coated implants. Comparing HA coated versus uncoated implants in the 500-700 μm bead diameter group, bone ingrowth (P = 0.01) and bone depth penetration (P = 0.008) were higher in HA coated samples. It can be concluded that the HA coating was an effective method for improving bone formation and ingrowth in the porous implants.
