An alternative method for direct custom tray construction using a visible light-cured resin.

The use of a properly made tray is highly desirable for impression making. To avoid the extra time required for tray fabrication, the alternative techniques of the putty wash or "reline" technique and intraoral fabrication of a custom tray by relining a stock tray with self-curing resin are proposed. This article illustrates a new technique of direct custom tray fabrication used for impression making for fixed prosthodontics. The proposed technique allows the direct fabrication of custom trays with light-cured resin and is time-saving, efficient, and inexpensive.
