No ring, no clamp, just Fendermate

A weak cervical junction under the contact point can cause an overhang.

The control with a probe or floss may give the impression of correct filling.

The access material is not bonded to the tooth structure.

After a period of time the occlusal pressure during chewing causes a facture of the access material.

The fractured surface creates a trap for food action and plaque retention causing caries and gingivits.

Sectional matrix systems, which consist of a matrix, wedge and ring, gives a risk of causing leakage due to lower pressure of the wedge against the matrix when the ring is applied to separate the teeth.

Fendermate sectional matrix for class II composite restorations

Fendermate is a pre-curved, one-piece sectional matrix and wedge that provides for quick, safe and predictable composite restorations, with a tight contact and cervical sealing.

Fendermate is designed to be inserted either buccally or lingually.

The matrix reaches from the base of the wedge to just a few millimeters above the occlusal surface.

The side of the wedge facing the adjacent tooth has an angled wing.

During insertion, the wing presses the matrix firmly against the preparation, giving a tight seal at the cervical margin.

To form the contact point the matrix has a pre-contoured indentation, which mimics natural contours.

When rubber dam is not used, it is suggested to secure Fendermate with waxed floss.
