The purpose of this study was to directly compare bone growth into identical porous coated titanium and cobalt-chromium canine implants. A transcortical screw was chosen as the cortical implant model. A straight cylindrical implant was used in cancellous bone. Quantitative analysis was performed using backscattered electron microscopy (BSEM) and computerized digital analysis. Cortical specimens were analyzed after six and twelve week periods of implantation. Bone ingrowth at six weeks for the cobalt-chromium implants averaged 50.4% $ pm$ 10.4% and for the titanium implants averaged 54.1% $ pm$ 5.1%. At twelve weeks, ingrowth for cobalt-chromium was 55.1% $ pm$ 9.2% and for titanium was 57.3% $ pm$ 9.3%. There was no statistically significant difference between the six and twelve week specimens or between cobalt-chromium and titanium for either time period. Cancellous implants were analyzed after twelve weeks and no difference in bone ingrowth between the two materials was observed.
