Patent

CA 2166046

A dental matrix of the type of a flexible strip, preferably made from a thin, strong, flexible material such as Mylar.TM.. Instead of the usual rectangular band, the strip tapers toward one end to provide a variety of sections having different width so that the overlap of a cavity, usually in the interproximal surface of a tooth, can be accurately made by simply sliding the strip to a desired position. As a result, there is an improved strength with which the strip envelopes the immediate vicinity of the filled cavity thus preventing undesired escape of the filling material towards the gum or towards the incisive part of the tooth. Two embodiments are disclosed.
