Four different surface modifications were designed. Forty screw-shaped
implants were divided into 4 groups, 10 screws in each. Every screw w
as prepared with 2 different surface topographies. The surface topogra
phy was measured with a confocal laser scanning profilometer and the s
urface roughness was characterized using 1 height, 1 spatial and 1 hyb
rid descriptive parameter. After 12 weeks in rabbit bone all screws we
re histomorphometrically evaluated. Blasted surfaces demonstrated more
bone in contact to implant surface compared with turned surfaces. Mos
t bone in close contact to implant surface was found for a surface bla
sted with 75 mu sized particles, numerically characterized with an ave
rage height deviation (S-a) of 1.4 mu m, an average wavelength (S-cx)
of 11.6 mu m and a developed surface area ratio (S-dr) of 1.5.
