Omschrijving

Polydentia’s Unica Proximal stainless steel matrices have a thickness of 0.03 mm and are available in two shapes (standard and deep), designed to fit the contour of the anterior teeth labially, palatally and proximally.

Unica Proximal matrices are especially indicated for anterior restorations involving the proximal walls (Class III and IV, peg-shaped lateral incisors, diastema closures, partial and total veneering). 

The easy-to-place cervical labiopalatal arch has the purpose of securing the matrix between the papilla and the tooth subgingivally, in order to improve matrix stability after placement. A wedge can be used to secure the matrix but it is not mandatory.

With a shape conceived to ensure an optimal fit on the anterior teeth, it affords better visibility and operatory field access than other solutions such as posterior sectional matrices.

Advantages:

• faithful reproduction of the labial, palatal and proximal contours
• allows unobstructed visibility and operatory field access, even when multiple matrices are placed at the same time
• self-stabilising: after placement, the matrix is stable and secured for the entire procedure, while allowing for the use of a wedge, where necessary
• longer cervical extensions than posterior sectional matrices, for easy restoration of the cervical part of the proximal contour
• available in two sizes (standard and deep) to ensure an optimum fit on different incisor morphologies 

The thickness of the matrix (0.03 mm) provides an optimum combination of formability (burnishing) and rigidity.

With the introduction of Unica Proximal, clinicians can now choose from an extended line of matrices that covers all anterior restoration situations.

Unica and Unica Minideep matrices can prove very useful in demanding cases requiring the restoration of the cervical and proximal areas (complete veneer).

Unica Proximal is the ideal matrix for restoring only the interproximal margin, without involving the cervical region, when unobstructed access and clear visibility are essential for a successful procedure, even when working mesially and distally at the same time.
