ABSTRACT:
A dental impression tray constructed from an optically transmissive material prepared with appropriately positioned recesses to direct light towards a U-shaped channel formed in the body of the tray. The channel is dimensioned to receive a portion of a patient's teeth. The recesses are formed in the outermost surfaces of the dental tray sides. In particular, multiple, spaced-apart recesses are formed in the outermost surfaces of the tray sides to deflect light into the channel area, which may have deposited therein a light polymerizable or curable material. Light is introduced into the tray through at least a first light portal which is integrally formed in a side of the tray.
