Abstract
A comparison was made between screw-shaped c. p. titanium implants bla sted with either 25- or 75-mu m particles of Al2O3. The implant surfac es were investigated with respect to topography and composition before implantation in rabbit bone. Grit blasting with 25- or 75-mu m partic les produced two different surface roughnesses, but no significant dif ference in the surface composition for the two surfaces. After 12 week s insertion time in the rabbit tibia and femur, a higher removal torqu e and more bone-to-metal contact was found for the implants blasted wi th 75-mu m particles compared with the 25-mu m-blasted ones.
