The Morelli Plastic Trays Upper & Lower #7 are sterilizable plastic impression trays supplied as a matched pair, one upper tray and one lower tray, both in size 7. The upper tray measures 77 mm (3.03 in) across the arch and 61 mm (2.40 in) front to back, with 32 mm (1.26 in) of lateral wall height; the lower tray measures 75 mm (2.95 in) across and 59 mm (2.32 in) front to back, with 26 mm (1.02 in) of lateral wall height. These dimensions define the dental arch this pair is selected for. Retention grooves molded into the base of each tray hold alginate in position, and the lateral wall height allows a complete impression of the dental arch.
Key Features
Base retention grooves hold the impression material against the tray base while the impression is taken.
Lateral wall height of 32 mm (1.26 in) on the upper tray and 26 mm (1.02 in) on the lower tray allows a complete impression of the dental arch.
Size 7 proportions pair an upper tray of 77 mm (3.03 in) by 61 mm (2.40 in) with a lower tray of 75 mm (2.95 in) by 59 mm (2.32 in), so both arches are recorded at the same size.
Sterilizable plastic construction allows sterilization in an autoclave at 121 °C (250 °F) or by chemical process.
Supplied as a pair: one upper tray and one lower tray are supplied together, ready for chairside use.
