EMPRESS-LithiCAD ( Empress Lithilium CAD/CAM) IPS e.max – one system for every indication IPS e.max is an innovative all-ceramic system which covers the entire all-ceramic indication range – from Thin Veneers to 12-unit bridges. IPS e.max delivers high-strength and highly esthetic materials for the Press and the CAD/CAM technologies. The system consists of innovative lithium disilicate glass-ceramics used mainly for singletooth restorations and high-strength zirconium oxide for large-span bridges. Every patient situation presents its own requirements and objectives. IPS e.max meets these requirements, because due to the system components you obtain exactly what you need. – The components for the Press technology include the highly esthetic IPS e.max Press lithium disilicate glass-ceramic ingots and the IPS e.max ZirPress fluorapatite glass-ceramic ingots for the fast and efficient press-on-zirconia technique. – Depending on the case requirements, two types of materials are available for the CAD/CAM technique: the innovative IPS e.max CAD lithium disilicate glass-ceramic blocks and the IPS e.max ZirCAD high-strength zirconium oxide. – The nano-fluorapatite layering ceramic IPS e.max Ceram, which is used to characterize/veneer all IPS e.max components – glass or oxide ceramics –, complete the IPS e.max System. www.ivoclarvivadent.com eMax- ZirCAD ( eMAx Ziconia CAD/CAM) IPS e.max ZirCAD are presintered yttrium-stabilized zirconium oxide blocks for the CAD/CAM technology. The blocks are available both shaded and unshaded. After sintering to full density, the material forms a polycrystalline oxide ceramic material made up of tetragonal zirconium oxide polycrystals (TZP). With a flexural strength of more than 900 MPa, the material demonstrates a high fracture resistance and its fracture toughness is more than twice that of glass-infiltrated ceramic. IPS e.max ZirCAD can be processed very easily in a CAD/CAM unit in its partly sintered, "chalk-like" state. Milling is always carried out with an enlargement of the framework of approximately 20–25 % per spatial axis. Given the controlled manufacturing process of the blocks, combined with an optimized sintering process in a high-temperature furnace from Ivoclar Vivadent, the shrinkage of the slightly enlarged, milled frameworks can be controlled in such a way that excellent accuracy of fit can be achieved. During the sintering procedure, the final, material-specific properties of the TZP are achieved. In the process, a structure that is densified to more than 99% is created, which features a high fracture resistance combined with high fracture toughness and thus fully meets the clinical requirements presented by masticatory forces – particularly in the posterior region. Therefore, IPS e.max ZirCAD supplements the range of indications of the IPS e.max materials in an ideal fashion. Either IPS e.max ZirPress is pressed onto the high-strength IPS e.max ZirCAD frameworks and/or the framework is veneered using IPS e.max Ceram. Cercon® ZirMAD ( Cercon Ziconia MAD/MAN)
Cercon® Zirconia is an innovative system for esthetic metal-free crowns and bridges. The reliability of Cercon ® Zirconia restorations is backed by more nine years of proven clinical success. The system is used to fabricate anterior or posterior single units or multi-unit bridge restorations out of translucent, biocompatible zirconia, the strongest and toughest dental ceramic. Cercon® Zirconia restorations can be placed with conventional cementation or adhesive bonding techniques. Over 225 Cercon Laboratories in North America offer Cercon® Zirconia restorations and over 3 million units have been placed worldwide since its introduction in May of 2002.
