Watertown, Massachusetts - Polyurethane use in dentistry is highlighted by a recent new material from Pulpdent Corp.-- Tuff-Temp Provisional Veneer, Crown & Bridge Resin.
The company says the proprietary chemistry of the material "provides greater strength and dimensional stability, and a tighter fitting provisional restoration compared to acrylics and bis-acrylics."
With the new resin, Pulpdent says "temporaries are tough, impact-resistant, and grip the teeth. Chipping, breaking, debonding, and recementations are minimised or eliminated."
Tuff-Temp is designed to grind and powder to produce accurate margins that do not soften or distort, the company claims, adding that "It does not gum up or clog finishing instruments."
