Dentatus
Nyström
Matrix
Retainers
Description
The
Dentatus
Nystrom
Matrix
Retainers
are
available
in
three
different
models:
‐
Models
MEC
‐
N1
and
MEC
‐
N2
hold
the
matrix
bands
at
slight,
opposite
angles.
They
are
marked
respectively
with
one
vertical
line
and
two
vertical
lines.
Figure
1
shows
which
model
is
used
for
which
quadrant
in
the
mouth.
The
angled
slot
makes
the
placement
and
holding
of
the
matrix
band
easier
and
helps
avoiding
distortion
of
the
band.
‐
Model
MEC
holds
the
matrix
band
straight
and
may
be
used
for
any
quadrant
of
the
mouth.
Placement
of
the
retainer
may
be
bucal
(recommended)
and
lingual
(only
recommended
during
restoration
of
the
buccal
wall)
(Figure
1).
