SEIL Global plastic impression trays are single-use, autoclave-incompatible disposable trays used as the primary carrier of alginate, silicone or polyether impression material during dental impression-taking. The rigid plastic body provides the dimensional stability needed to record the patient's arch, while the perforated retentive design holds the impression material in place during seating and removal — minimizing distortion and improving the dimensional accuracy of the cast. Supplied as 100-piece bulk packs (Plastic Tray Set) and as anatomically profiled assortments (Plastic Impression Trays) covering upper, lower and partial-edentulous arches in standard size ranges. Single-use design supports cross-infection control and eliminates between-patient cleaning.
