The invention provides a light curing method, including: providing a light curing apparatus having at least one light source, at least one fan and a curing volume. A first polymerizable shaped material is positioned within the curing volume. The light source and the fan are controlled to heat the first polymerizable shaped material to temperatures within a first temperature range. The light source and the fan are controlled to maintain the first polymerizable shaped material at temperatures within the first temperature range for at least 1 minute. A second polymerizable shaped material is positioned within the curing volume. The light source and the fan are controlled to heat the second polymerizable shaped material to temperatures within a second temperature range. The light source and the fan are controlled to maintain the second polymerizable shaped material at temperatures within the second temperature range for at least 1 minute. The first temperature range has a first midpoint and the second temperature range has a second midpoint. The first midpoint is at least 15° C. from the second midpoint.
A light curing method, comprising:
4 The method of claim 3 wherein said denture forming product is maintained at temperatures within said first temperature range for at least 2 minutes, and said first temperature range has a midpoint temperature between 100° C. and 110° C.
Dependencies are inferred from the claim text.
