Matrixing Strategies for the Anterior and Facial Surfaces
The purpose of a matrix is to function as a shape-former and facilitate the placement of materials such as amalgam or composite resin. Many options are available in terms of material selection and scope; this article will discuss various matrixing options as applied to anterior or facial composite restorations. Metal and plastic matrices will be discussed, specifically, as well as sectional and “full-contour” ones.
Plastic matrices: Mylar matrices are a ubiquitous part of every clinician’s armamentarium. Their many advantages include malleability, the ability to cure through, and the resultant highly polished surface when cured against composite.1,2 Issues can arise in areas of tight or irregular contacts, where the thin Mylar may not be able to traverse or may warp. Also, the thin strip may not hold its shape as readily as a metal matrix, though there are protocols to negate this effect,3 and stiffer anatomical Mylar matrices are available...
