Custom trays are indispensable for making impressions with elastomeric products. Previous studies have demonstrated that certain autopolymerized materials are particularly suitable, but had some limitations. The recently introduced halogen-light-polymerized resins permit fabrication of custom trays that have the needed physical properties for accuracy and strength. No storage period is necessary for completion of polymerization, and the trays are not subject to distortion in moisture, making them suitable for use in the electroforming of casts.
