A dental matrix band ( 1 ) having a brace extrusion window ( 4 ), a flash guard ( 14 ) and guard brace ( 22 ) which fold to articulate into a conventional Tofflemire-like matrix band shape. The flash guard ( 14 ) is secured by the guard brace ( 22 ) against the brace extrusion window 4 . This serves as a barrier to temporarily block a restorative substance from passing into an inter-proximal space. After cutting a connecting severance junction ( 30 ), the flash guard ( 14 ) is removed via a removal tab ( 16 ) and aperture ( 18 ). The restorative material is then displaced to created direct contact with an adjacent inter proximal surface through the window 4 . After polymerization, a series of linearly aligned notches ( 28 a,b,c,d), superior window notches ( 8 a,b), inferior window notch ( 10 a,b) and gingival notch ( 12 a,b) permit a vertical bisection split through the matrix ( 1 ) conjoined aperture( 25 ). This facilitates the matrix ( 1 ) removal from a cured contact point.
