ABSTRACT:
A matrix segment of sufficient size to cover the interproximal area of a tooth restoration is shaped for patient comfort, easy application, and easy removal. The smooth tapered shape of the segment sides provides adequate tooth coverage and minimizes potential gingival laceration. An aperture is located in the segment so that it may be conveniently pulled away after use with a string-like material, such as dental floss.
