Pulpdent releases new provisional material category

May 3, 2010
Tuff-Temp is, a proprietary rubberized-urethane provisional material.
WATERTOWN, Massachusetts--Pulpdent Corporation has introduced rubberized-urethane, a new category of provisional materials. During the past two decades, many practitioners have favored bis-acrylic provisional materials from Germany as compared to traditional powder and liquid acrylic. By inserting a synthetic rubber molecule into a diurethane dimethacrylate molecule, Pulpdent has developed Tuff-Temp, a proprietary rubberized-urethane provisional material.Bis-acrylics have the convenience of automix systems, but they are brittle, shrink, and stretch. They also break, come loose, and require frequent re-makes and re-cementations. The heat generated by grinding can gum up and distort the margins and clog finishing instruments. Powder and liquid acrylics are strong, grind, powder for accurate margins, and are low in price. However, they shrink and stretch, are highly allergenic, can have an objectionable odor, generate considerable heat, fit poorly, come loose, and require frequent re-cementation.Tuff-Temp’s rubberized-urethane chemistry, available in automix cartridges and syringes, is tough, impact-resistant, and dimensionally stable. It grips the teeth and reduces or eliminates chipping, breaking, debondings, and recementations. Suitable for single units and longer spans, Tuff-Temp grinds and powders, providing crisp and accurate margins. The heat of the grinding and finishing instruments does not soften or distort the rubberized-urethane.Tuff-Temp is dual-cure. The fast light-cure option produces a full-strength restoration on demand and works with a clear vinyl polysiloxane template. Tuff-Temp Glaze and Add-on are also available for enhanced esthetics, alterations, and smile design. They are made from the same rubberized-urethane chemistry.For more information, call (800) 343-4342 or visit read more about Pulpdent, go to comment on this product, go to
