b. Matrix Bands and Band Material (BAND, MATRIX, DENTAL; BAND SET,
MATRIX, DENTAL; BAND, COPPER, DENTAL; PLASTIC STRIP, DENTAL MATRIX).
Matrix bands (figures 2-11, 2-12, and 2-13) are used to form missing walls of prepared
teeth. They shape and confine restorative materials and wax to areas prepared to
receive restorations. These include Ivory matrix band sets, Tofflemire matrix band sets, a
cervical set, plastic celluloid strips, and metal matrix strips. Related materials include a
celluloid matrix wedge and a crown form set. Celluloid crown forms are designed for
specific teeth and are used as matrices for Class IV restorations.
