Application Sectional Matrices
OShape
The selected WALSER® Matrix must be pointing in an occlusal direction, and it is from this side that the forceps are applied. Spread out the WALSER Matrix Forceps to the point where the first notches on the tip of the forceps engage in the recesses of the matrix springs. 

Slip the matrix over the tooth and insert in the interdental spaces. Relax the forceps when the papilla is reached. The strips will then wrap around the neck of the tooth. Then shift the matrix accordingly in an occlusal direction. 

Once the tooth filling has been placed then retension the matrix to maximum point. This is important so as not to damage the well contoured filling. Before removing the matrix it should be moved by a gentle rocking motion around the sagittal axis, as this will release the strips more easily from the filling material.
