The Perforated Impression Tray – Upper Jaw – Size L is made of stainless steel and is intended for routine dental impression procedures on the upper arch. Its perforated body lets the impression material lock through the openings, and the Rim-Lock rim helps retain the set material on removal. The tray is reusable and fully autoclavable, making it suitable for repeated use in busy clinics. A stable stainless steel structure resists flexing during the impression, and the handle gives a firm grip when seating and lifting the tray. Size L suits large upper-jaw arches encountered in daily practice.
