is reached a higher implant stability at the early osseointegration phase, as is
shown in clinical data and animal studies.
This method is globally proved for hip-, knee-, shoulder-, wrist- and tooth implants.
The spinal application thus appears to be logical.
Nowadays commercially successful implant systems have an optimal and
reproducible surface topography. Additional to those, ADONIS ® Exclusive has
an optimized and reproducible surface chemistry, which leads to an improved
wettability and hereby a more homogenic blood contact with the implant surface.
The result of this is a faster implant osseointegration, facilitating an earlier load.
Summery
The long-term success of an implant therapy concept is determined by multiple
factors, but mainly by the bone density of the implant bed, the implant design and
implant surface.
The composition, roughness and topography of the implant surface at the interface
are playing an important role for the primary stability and a safe osseointegration.
Rough implant surfaces will influence and stimulate the cellular activity of
surrounding bony structures. The cell proliferation and cell differentiation, matrix
Osseointegration and Friction
synthesis and production of the „Tissue Growth Factors,“ are promoted and will
lead to a dense bone-implant connection.
Specific surface roughness of the implant will promote the regeneration potential at
the interface and thus the clinical implant fixation.
Compared to machined implant surfaces the moderately rough surface (Fig. 14
- „HENIAPORE-K“) of ADONIS ® Exclusive shows denser bone apposition with
significantly increased withdrawal force (load removal) and an extremely high
coefficient of friction for primary stabilization.
This results in an accelerated osseointegration of these implants and the possibility
of an earlier exposure.
