COE Nickel-Plated Perforated Impression Tray, #4 Medium Upper, Full-Arch, 1/Pk, 260041

COE Nickel-Plated Perforated Impression Trays are a long-standing choice among dental schools and clinicians for reliable, reusable impression taking. This #4 medium upper full-arch tray is made of rigid yet bendable nickel-plated metal with welded rim-lock borders that allow pressure build-up and resist distortion, while the perforated design promotes retention of impression material. Each tray measures approximately 2-7/8" W x 2-3/8" L x 7/8" D and is sold individually; use of a tray adhesive is recommended to prevent separation during removal.
