Long-term restorations should be reliably stable and simultaneously satisfy high requirements as far as a natural look that appeals to the patient is concerned. Digital prosthetics impress with first-class results, as even the minutest of details can be processed with the assistance of computers. For particularly aesthetically pleasing restorations, VOCO is offering with Grandio disc multicolor a new product complementing the existing shades of the nano-ceramic hybrid material Grandio disc. The multicolor version imitates the colour gradient of natural teeth from the incisal edge to the tooth neck – and that with just three layers.
The special composition of the material reflects and absorbs light to create the particularly intense chameleon effect, which allows the individual layers of the restoration to transition into each other and produces a highly aesthetic colour gradient. The optical adaption to the neighbouring teeth and the overall aesthetic appearance also benefit from this effect.
Invisible layer technology
The restorative is divided into three layers: one for the incisal area, one for the basic tooth colour (dentine layer) and one for the cervical area.The colouring of Grandio disc multicolor makes the restoration look very vital, which is achieved with just these three layers due to the material properties (invisible layer technology). When developing Grandio disc multicolor, special importance was attached to remaining in the original shade family (e.g., A1 HT, A2 HT) of the Grandio disc (monocolor) so as to ensure that all products can be combined. The VITA® shade system was choosen for selection of the correct shade: Grandio disc multicolor is available in the six shades A1, A2, A3, A3.5, B1 and C2. The designated shade is the middle layer (basic tooth colour). Restorations made from Grandio disc multicolor imitate the natural colour gradient of the tooth from the incisal edge to the tooth neck even without individualisation.
Indications
Just like the monochromatic version, Grandio disc multicolor has a thickness of 15 mm and a diameter of 98 mm. It is indicated for the manufacture of single-tooth restorations such as crowns, inlays, onlays, veneers and implant-retained crowns.
About Grandio disc
The completely polymerised Grandio blocs/disc products set new standards with their far superior material strength: with a filler content of 86%, the material is the most highly filled in its class. The biaxial flexural strength also achieves values which are normally only associated with silicate ceramics, but Grandio blocs/disc is significantly more antagonist-friendly.
The material can be milled very finely and is easy to polish, allowing the restoration both to fit perfectly and to meet high aesthetic demands. With Grandio blocs/disc it is possible to manufacture restorations which have very thin walls and are yet stable, such as veneers, which additionally protects the dental hard tissue. When nanoceramic hybrid materials are used, there is no need for the time-consuming firing process.
The discs are processed in the milling devices in the same way as the Grandio disc in the monochromatic LT‑and HT shades. An overview of our numerous trusted partners can be found here
