Abstract: Samples of dense aluminum oxide, dense, porons, and surface-oxidized titanium of varying surface roughness and containing long cylindrical channels 95-1000 p in diameter were implant,ed in viva in dog femurs for period9 of 2-8 weeks. The depth of ingrowth of calcified tissue into t,hese channels was det,ermined as a function of time, principally by electron microprobe.The most rapid bone ingrowth was obtained with NO-, 5 2 5 , and 1000-p diameter channels in all the titanium and aluminum oxide samples. Howeve…
