ABSTRACT:
A novel hand-held pressure molding device about the size of a pair of pliers is used to produce a contoured matrix of dental restorative composite resin for use in restoring teeth to their approximate original shape. The matrix produced by the device is bonded in place to establish the old contour of the tooth and then the space between the tooth and the matrix is filled with uncured dental restorative composite. After curing by actinic light, the matrix bonds to the rest of the filling and the tooth, forming the outside contour of the restored tooth. The present device avoids the need for supplying preformed and pre-shaped dental matrices in multiple shapes and sizes to the dental practitioner, allowing the practitioner to manufacture his matrices in his office from the identical material subsequently used to fill a tooth.
