Özet

Our
study
is aiming
retrospective
survey
of the
corrosion
resistence
of above
-stated
silver
and
hydroxyapatite
covered
pedicle
screws
depending
on
routinely
surgery
used
Ti and
Ti
-6Al
-4V
compounded
pedicle
screws.
32
pedicle
screw
coverings
in different
sizes
removed
after
the
revision
surgery
were
separated
into
three
groups
(Ti
-6Al
-4V,
Silver
Covering
and
Hydroxyapatite
Covering).
Screws
in every
group
were
measured
in order
of diameter
(mm)
and
severity
(gram).
The
implanted
residence
times
(day)
of
pedicle
screws
in patients
were
recorded
by
using
patient
records.
According
to the
results,
we
observed
that
silver
and
hydroxyapatite
covered
pedicle
screws
and
time
have
a correlation
relation
in a positive
way.
However,
this
situation
is total
opposite
for
Ti-6Al
-4V
pedicle
screws.
Any
correlation
relation
in a positive
way
between
severity
difference
and
time
wasn’t
found
in any
pedicle
screw
group.
Hydroxyapatite
and
silver
can
not
be
used
unattended
in the
body
because
of their
biomechanic
re
sistance
and
various
toxic
features.
When
they
are
added
on
to the
Titanium
screws
with
different
covering
techniques,
biocompatible
and
antibacterial
surgical
instruments
are
obtained.
Our
purpose
is improving
very
image
of hydroxyapatite
and
silver
cover
ing
materials
with
succesful
results
we
gained.
