[Provisional restorations in fixed prosthetics. Combination of photopolymerizing resin and composites]

This study shows the interest of using a light cured resin for temporary restorations. The rubber like stade enables easy removable of undercuts and excess material can be trimmed easily before light irradiation. Physico-chemical properties of light cured resin are compared with those of four chemical-polymerizing resins. Exothermic reaction, transverse strengths, modulus of elasticity, and differential scanning calorimetry show the same values as the best autopolymerizing resins. The author presents an original technic, using the light cured resin with light cured composites to achieve aesthetic and strong temporary restorations.
