Directa, 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.

4 reasons to use FenderMate®

#1 Predictable contact and anatomic shape

The pre-shaped contact adapts to the proximal surface and forms the optimal contact and anatomic shape.

#2 One piece design

Matrix and wedge combined for easier and safer placement.

#3 No cervical overhang

The wing design exerts pressure for maintained separation and cervical margin adaptation.

#4 Designed for minimally invasive dentistry

Can be inserted interproximally with minimal preparation.

Cervical Overhangs, A Mistake Easy To Miss

A weak cervical junction under the contact point can cause an overhang. The control with a probe or floss may give the impression of a 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 impaction and plaque retention causing caries and gingivitis. Sectional matrix systems which consists 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.
