Abstract
Abstract A dental impression tray has wall portions defining at least one channel for receiving a quantity of photocurable dental impression material. At least one of the wall portions is located next to the chamber and is made of a material that transmits electromagnetic actinic radiation. The tray also includes a chamber for receiving a chemiluminescent composition. Light emitted from the chemiluminescent composition induces the curing of the impression material in a uniform manner along the length of the channel.
