HA layer is sintered onto the surface of zirconia ceramic material.These column-like composite implants and titanium implants were inserted into the femurs of the dogs.The speciments were taken at the third month after operation,and the shear strengths between the implants and bone were measured.The undecalcified bone section containing the composite ceramic implant were cut for light microscopy,scanning electron microscopy and elemental analyses of C,P and Zr.Mechanical testing results revealed that the attachment strength of HA-coated zirconia samples is more stronger,as companied with the titanium samples.Histologic evaluations of the undecalcified specimens showed that extremely close juxlaposition of bone to HA-coated zirconia ceramic implants was seen. |
