The invention relates to a dental fixture for insertion into a human jawbone. The fixture comprises a bone-contacting surface, wherein at least 15% of the bone-contacting surface is designed such that when a Gaussian 50 µm high-pass filter and a Gaussian 3 µm low-pass filter is applied to an original unfiltered set of measurement data which represents a topography of said surface and which is obtained at 50 times magnification by white light interferometry, the resulting filtered set of data presents a surface roughness having the roughness average parameter S a ‰¥ 1 µm and the two-dimensional mean slope parameter R sl ‰¥ tan 30°.
