COE Nickel-Plated Perforated Impression Tray, #21, Medium/Large, Lower, Full-Arch, 1/Pk, 260211

COE Nickel-Plated Perforated Impression Trays are a long-standing first choice among dental schools and clinicians worldwide. The #21 lower full-arch tray is rigid yet bendable for an individual fit, with welded rim-lock borders that allow pressure build-up and help prevent distortion during impression removal. Perforated nickel-plated construction promotes retention; tray adhesive is recommended to eliminate separation. Sold individually (1 per pack), reference #260211.
