The needs are different:
Individual unattached Implant is immobile when
No evidence of Peri Implant radiolucency
The mean vertical bone loss is < .02mm
annually after the first year
No persistent pain,discomfort or infection is
attributable to the Implant

Emanating from existing bone, new bone
is formed by osseo conduction directly on
the implant surface following the contour
of the threads.
The osteogenic cells differentiate into
By this,always new osteogenic cells,
socalled pre osteoblasts,must be recruited
from stem cells and have to migrate to the
front part of bone formation.
Pre osteoblasts form cytoplasmic
extentions,socalled pseudopodia, which
are important for both cell attachment and
migration on solid surfaces.
By means of pseudopodia, pre
osteoblasts make use of porous structures
of implant surface to migrate and become
Pre osteoblasts become differentiated into
osteoblasts and start the secretion of bone
Subsequently, the collagenous bone
matrix becomes minerallized and
deposites of woven bone are formed
directly on the implant surface.
There by, initially a small band of woven
bone follows the contour of the
threads.This small band broadens and
matures to lamellar bone.
