Abstract
A process for preparing dental restorations includes the steps of applying a composite restorative material onto a prepared tooth followed by the application of light to the composite of intensity sufficient to penetrate the composite to initiate polymerization. Light application is then suspended for a period of time sufficient to allow for the relaxation of internal stresses created by the initial polymerization of the composite. Light is subsequently applied to the composite to complete polymerization.A curing light is utilized which includes variably-adjustable, multiple power and timing settings.
