Abstract:
1. A method for light-curing polymerizable materials to form a dental device, comprising the steps of: providing a light-curing apparatus having a least one light source and a curing volume; positioning a first polymerizable material within said curing volume; heating said first polymerizable material to a temperature within a first temperature range; maintaining said first polymerizable material at the temperature within said first temperature range for at least one minute; positioning a second polymerizable material on said first polymerizable material that has been at least partially polymerized, within said curing volume; heating said second polymerizable material to a temperature within a second temperature range; and maintaining said second polymerizable material at the temperature within said second temperature range for at least one minute, said first temperature range having a first midpoint and second temperature range having a second midpoint said first midpoint temperature being at least 10° C. apart from said second midpoint temperature; wherein the intensity of light energy and heat energy imparted on the first polymerizable material is controlled to cure the first polymerizable material while not causing a substantial deformation of shape; and wherein the intensity of light energy and heat energy imparted on the second polymerizable material is controlled to cure the second polymerizable material while not causing a substantial deformation of shape.
