Modified matrix adaptation for sub-gingival Class II amalgam restorations.
Proper placement of the matrix and wedge is critical for the success of Class II amalgam restorations. Improper placement of matrix and wedges can result in poor contours or contacts, overhangs or weakness resulting from poorly condensed restorative material. This paper presents a technique for adaptation of a combination of matrix bands in cases where the gingival cavosurface margin extends deep sub-gingivally.
