Custom impression trays can be constructed from acrylic resin,light-cured resin,or thermoplastic resin.
Custom impression trays are made from a preliminary model before the dentist has prepared the teeth.
Custom impression trays are available as quadrant trays that cover half an arch,section trays that are used to cover the anterior portion of the arch,and full-arch trays that cover the entire arch.
When a smooth surface tray is used,there is no mechanical lock,so the interior of the tray is painted or sprayed with an adhesive to hold the impression material securely to the tray.
