Abstract

The main goal of the present invention is the development of a polymerizable material for isolation and protection of the gums and generally the soft tissues of the oral cavity. For better protection during various procedures of the dental surfaces. The composition of the material can contain many other substances that strengthen its qualities and protective action. Such substances can be various substances that have antioxidative, sedative, anti-inflammatory, analgesic, anti-irritant action etc.

Claims (13)

40% to about 99% of urethane dimethacrylate by weight of barrier;

at least one activator to activate the diurethane dimethacrylate, wherein the activator comprises from about 0.01% to about 5% of camphorquinone or 9,10-anthraquinone by weight of barrier;

10% to 25% vitamin E by weight of barrier; and

at least one filler, wherein the at least one filler includes silica.
