Topographical parameters analysed by blue light profilometry of the titanium surfaces used in the studies.

	TiOblast	OsseoSpeed	P
S a/μm	0.77 ± 0.06	1.35 ± 0.04	8.3E − 08
S sk	−0.38 ± 0.05	−0.2 ± 0.08	0.003
S ku	3.92 ± 0.05	3.46 ± 0.11	0.00002
S ci	1.41 ± 0.02	1.47 ± 0.02	0.002

Mean values and standard deviation are presented (n = 5, 3 combined measurements per sample); Student's t-test being performed between “TiOblast” and “OsseoSpeed”. Legends: S _a: average height deviation from the mean plan, S _sk: surface skewness, S _ku: surface kurtosis, and S _ci: core fluid retention index.
