Abstract
Method of the making dental restorations having photo-initiated polymerizable dental compositions. The method comprises preheating a dental restoration precursor of a defined shape or anatomy in a temperature range from about 65.degree.-120.degree. C. for a length of time for the temperature to reach a temperature equilibrium. The time preferably ranges from about 1 minute to 30 minutes. Thereafter, the dental composition is light cured to polymerize the dental restoration. The restoration produced through this process will have at least 10% or higher strength than the dental restorations made by conventional methods.
