Custom tray materials are used to create personalized impression trays for more precise dental impressions. Unlike stock trays, custom trays are tailored to fit a patient’s unique oral anatomy, ensuring better accuracy for crowns, bridges, dentures, and other restorations.These materials are typically available in light-cure sheets, self-cure resins, and thermoplastic options. Light-cure sheets harden under UV or visible light, providing a quick and controlled setting process. Self-cure resins chemically harden over time, offering a strong and stable tray. Thermoplastic materials soften with heat and can be molded directly for an adaptive fit. Custom trays improve impression accuracy by maintaining uniform material thickness and minimizing distortions. They also help control impression material usage, reducing waste. Proper handling and curing of custom tray materials are essential for achieving the best results.
