Predictable contacts with OptraMatrix ®
selectively thinned band with unique window
Selectively thinned matrix band
(10 µm) for tighter contacts
OptraMatrix Conventional Conventional
circular matrix
sectional matrix
The new OptraMatrix bands are selectively
thinned on the side of the cavity. This thin
area allows tighter and broader proximal
contacts to be achieved, as the tightness of
the contact is directly related to the thinness
of the matrix material between the teeth!
There is no need to make space by forcing
the adjacent teeth apart using wedges.

Window for close contact surfaces
The matrix bands feature a window on the
opposite, uninvolved side of the cavity.
Therefore, the natural contact of a two-surface
cavity remains intact during the treatment,
preventing counterproductive
micro-movements of the
tooth to be treated.
The matrix has a selectively
thinned contact area (10 µm)
to reduce the amount of matrix
between the teeth during the
treatment procedure.
The special shape of OptraMatrix
achieves an excellent cervical seal
and allows the matrix to automatically
adapt to the adjacent
tooth.
The stable basic thickness
of the matrix is 45 µm
(normal basic wall thickness)
Thanks to the window, the
existing contact on the
uninvolved side remains intact
during the treatment.
Controlled positioning of the contact
The contact can be created in the upper
third of the proximal surface so that the
entire restoration imitates the original
natural situation much more closely than
if conventional matrices are used.

Easy to use with conventional Tofflemire
matrix retainers
OptraMatrix bands have been developed for
use with conventional Tofflemire retainers.
Therefore, they can be integrated into routine
procedures quickly and easily. Minimum
adaptation of technique – maximum benefits!
