34 I I industry news _ VOCO _GrandioSO, the new, universal nano-hybrid restorative for all classes of cavity, meets the highest demands for restorations in anterior and posterior regions.GrandioSOissuitableforClassItoVrestora- tions, reconstruction of traumatically injured an- terior teeth, interlocking and splinting of loosened teeth, corrections of shape and shade to enhance aesthetic appearance, core build-up for crowns, and the fabrica- tion of composite inlays. As it offers superb ma- terial properties, GrandioSO is a most toothlike material with re- gard to its physi- cal parameters. It allows for equally durable and aesthetic restorations, owing to averyhighfillercontent(89w/w%)andlowshrink- age (1.61 %), a high compressive and flexural strength (439 MPa and 187 MPa, respectively), an E-modulus (16.65 GPa) and thermal expansion behaviour ( = 27.3 x [10–6 x K–1 ]) similar to dentine, averyhighsurfacehardness(210,9MHV),lowabra- sion (18 µm, ACTA with 200,000 cycles), as well as the optimal balance of translucence and opacity. GrandioSO polishes very well and owing to its outstanding abrasion resistance the restoration remains permanently lustrous. With 16 different shades, including the new shades VC A3.25 and VC A5, theentirespectrumrelevanttodentistryiscovered. GrandioSOHeavyFlow,ahigh-viscosityflowable universal nano-hybrid restorative, has a very high filler content (83 w/w%) and exceptional stability in comparison with conventional flow composites, as well as excellent wetting properties. Thus, it is recommended for any type of treatment that requires these qualities. For compos- ite restorations that are directly modelled in the mouth, the increased viscosity results in simplified and stress-free place- ment of the composite layers. GrandioSO Heavy Flow is suitable for minimally invasive restorations ofalltypes;restorationsofsmallClassIcavitiesand extended fissure-sealing; Class II to V restorations, including treatment of cuneiform defects and cer- vicalcaries;blocking-outofundercuts;repairoffill- ings and veneers; luting of translucent prostheses (for example, full ceramic crowns); and interlocking and splinting of teeth with glass-fibre strands such as GrandTEC. It can also be used as base material, in combination with glass-fibre strands, for the fab- rication of semi-permanent crowns and bridges. _Optimal handling Owing to its smooth consistency, GrandioSO is readily packable and sculpts well without sticking to the instrument. In addition, it combines excep- tionally long workability under ambient light with very short setting times during subsequent poly- merisation.Itispossibletocurethematerialreliably in 10 seconds per 2 mm increment. GrandioSO is available in easy-to-use rotating syringes and par- ticularly economical caps. GrandioSO Heavy Flow is subject to far lower shrinkage than conventional flow materials during polymerisation (2.96 %). It also features high compressive and flexural strength (417 MPa and 159 MPa, respectively), an E-modulus that is extre- melyhighforaflowablematerial(11.85GPa),ahigh surfacehardness(175MHV),aswellaslowabrasion (40 µm, ACTA with 200,000 cycles). This slow flow- ing composite, which complements flowables with conventional viscosity, offers users many advan- tages. On the one hand, it offers a longer working period during which the material can be placed in the cavity and distributed before polymerisation; on the other hand, less time is required for the re- moval of any excess due to running of the material. Owing to its reduced flowability, GrandioSO HeavyFlowiswellsuitedtoallfillingsthatdonotre- quire elaborate sculpting. Its excellent material and handling properties make GrandioSO Heavy Flow superior to many packable composites. GrandioSO Heavy Flow is available in a non-run, non-drip NDT syringe in ten shades and as caps in five shades. GrandioSO and GrandioSO Heavy Flow may also be used in combination._ cosmeticdentistry 3_2010 VOCOGmbH P.O.Box767 27457Cuxhaven Germany Website:www.voco.com cosmeticdentistry _contact Grandio® SOandGrandio® SOHeavyFlow
