BIOLOX - Nanocomposite for Arthoplasty

Superiority in Extreme Conditions
Polyethylene
Ceramic
Foreign particles that
are harder than the
bearing surface lead to
high levels of wear (left).

Surfaces made of high
performance ceramics
remain largely unchanged
even when
exposed to ceramic
particles (right).

Ceramic
No Third-Body Wear
Unsurpassed hardness prevents surface
damage to the articulation by third-body
wear in ceramic-on-ceramic bearings.
Foreign particles are broken down and
extruded without damaging the bearing
surfaces.
Scratched surfaces
increase abrasion in
cup liners made of
PE, XPE and metal.
No Scratches
Cement particles and surgical instruments
are not able to scratch ceramic surfaces –
an important advantage when using
cement and minimally invasive procedures.
Highest Degree of Biocompatibility
Clinical experience shows no known longterm
adverse reactions to ceramic particles.
Ceramic materials are entirely biologically
inert and exhibit unmatched biocompatibility.
Excellent Wettability
Hydrogen bonds between ceramic surfaces
and synovial fluid ensure excellent wettability
and the formation of an effective
lubricating film.
Only an unscratched,
smooth surface of the
sort achieved in BIOLOX ®
ceramics enables optimal
wetting, outstanding
lubrication and minimal
wear.
The strong hydrogen
bonds that form between
ceramic surfaces
and synovial fluid give
ceramic materials wetting
properties that are
superior to those of
metal and polyethylene.
