Functions of Tofflemire Matrix Systems
Provide a temporary wall of resistance to the pressure necessary for the restoration
Types of Tofflemire Matrix
Proximal surfaces restored using the matrix require more carving than those restored with the compound supported matrix
Wedges
Anatomical ( triangular wedges ) is recommended for deeper and / or wider proximal preparations.
