3M (Solventum) Chairside Zirconia Crown Block for CEREC, 20 mm, Shade BL (Bleach), Refill 5/Pk, 69940
3M (now Solventum) Chairside Zirconia Crown Blocks are CAD/CAM zirconia blocks designed for the CEREC SpeedFire furnace, offering a well-balanced combination of high strength and esthetics for single-unit crowns and 3-unit bridges. The 4Y zirconia provides a high flexural strength of 1000 MPa after fast firing and a fast sintering time of approximately 20 minutes for thin-walled crowns, enabling a scan-to-seat workflow in about one hour. Pre-shaded in the ultra-light Bleach (BL) shade to match the VITA classical shade guide, the 20 mm blocks allow a minimum wall thickness of 0.8 mm for less invasive preparations. Each refill package contains 5 crown blocks.
