Custom Impression Tray Fabrication for Crown
and Bridge Application
Soften Easy Tray wafer in thermal unit/hot pot by immersing in water for at least 30 seconds. Water temperature must be 170°F (77°C) or hotter.
Using tongs, remove Easy Tray wafer from water and mold it around the disposable fluoride tray.
Pinch Easy Tray material anteriorly to form a custom tray handle. Excess tray material should be rolled back onto the tray to add strength as the Easy Tray material adheres readily to itself in its softened state. If the tray material begins to set, immerse in hot water bath for a few seconds and then continue to mold and shape the custom tray.
Place fluoride tray with the adapted Easy Tray into patients mouth to check the fit.
Remove both spacer material and Easy Tray custom impression tray simultaneously as a unit without distorting and place under cold tap water until thoroughly cooled and hard (about one minute).
Remove spacer material and dry custom tray with air syringe.
Easy Tray is now dimensionally stable and ready to use.
Paint the internal surface of the custom tray with the adhesive that is recommended for the impression material that you are using.
You are now ready to take your impression.
