Function of matrix band:
A. Substitute for the missing wall so adequate condensation forces can be applied
B. Permit re-establishment of proper contact lines
C. Restrict extrusion of amalgam and prevent formation of an “overhang”
D. Provide adequate physiological contour for the proximal surface
E. Provide an acceptable surface texture to the proximal surface
F. All of the above
