PlanMill milling units from Planmeca now can use Ivoclar Vivadent’s Tetric CAD aesthetic composite blocks and IPS e.max ZirCAD zirconium oxide materials, giving practitioners more opportunities to produce high-quality restorations at chairside, the companies report. Also, three new shades have been added to the range of Telio CAD cross-linked PMMA blocks.
Tetric CAD is designed for the efficient production of single-unit restorations. Due to its pronounced chameleon effect, restorations using it optically blend into the existing tooth structure, the company says. Also, the block is designed to be easy to use and efficient to process, with restorations that can be milled and polished quickly and then seated using an adhesive technique. Blocks are available in MT and HT levels of translucency in five and four shades respectively and in sizes I12 and C14.
IPS e.max ZirCAD LT (low translucency) is a monolithic zirconium oxide block designed for crowns and three-unit bridges. It allows posterior crowns to be designed in a reduced wall thickness of 0.6 mm and anterior crowns in a reduced thickness of 0.4 mm due to its high mechanical strength of 1,200 MPa and high fracture toughness of 5.1 MPa, Ivoclar Vivadent says. The reduced thicknesses increase the translucency of the restorations and benefit the aesthetic outcome, the company says.
Also, a fluorescent effect can be achieved with IPS e.max CAD Crystall./Glaze Fluo. The restorations are placed using either a conventional cementation technique or a self-adhesive resin cement, such as SpeedCEM Plus. Sintering is carried out in the Programat CS4 furnace. The LT blocks are available in BL, A1-3, B1-2, C2, and D2 shades.
Shades B3, C2, and D2 have been added to the range of Telio CAD blocks for PlanMill as well. As a result, the cross-linked PMMA blocks are now available in nine LT shades (BL3, A1, A2, A3, A3.5, and B1, in addition to the three new shades) and in two different block sizes (B40L and B55).
Ivoclar Vivadent offers a treatment concept that empowers practitioners to restore the dentition of their patient in a single visit, the company says. In addition to the blocks and cementation materials, the range includes coordinated materials for the entire restorative workflow starting from the OptraGate lip and cheek retractor to luting materials and oral care products.
