In this chapter, we shall explain bone properties based on a number of concepts, each illuminating one specific aspect of the osseous life cycle. All of these concepts are applicable at the same time, and they are indeed relevant for our implantological work.

However, they never attain an absolutely straight form, since the last bit of straightening requires a mechanical stimulus that is absent. The lower the residual curvature, the lower the stress facilitating the residual straightening effort, that is, the change in concavity according to Frost’s FNT theory.
If bone really were to resorb under pressure, the bones in our feet would have to be shrinking – particularly the heel bone! People would be buying smaller shoes and shorter trousers on a regular basis.
Based on the standards used in crestal implantology, this case is characterized by bone loss of more than one-third of the implant length in one-third of all implants 6 years after implantation. Going by these criteria, the implant system would not meet the standards of scientific dentistry. Also see Albrektson et al. (1986).
