Ceramic Restorations

The development of high-strength all-ceramics has provided an alternative to porcelain-fused-to metal (PFM) restorations. Restorations made from a monolithic all-ceramic material eliminate many of the problems dental professionals faced with metal-ceramic and fully layered zirconia frameworks, such as fractures and/or chips in the porcelain material that can contribute to decreased esthetics and function. However, in their early existence, zirconia materials lacked natural esthetics. With advanced technology and material developments, zirconia and lithium disilicate have come a long way. Both IPS e.max CAD and IPS e.max ZIRCAD zirconia from Ivoclar Vivadent demonstrate high strength and a natural appearance. Using CAD/CAM technology, we can design the restorations virtually, then mill IPS e.max CAD or IPS e.max ZIRCAD zirconia blanks monolithically into crowns and bridges with either minimal hybrid layering or, without the need for applying a veneering ceramic.

ZEN- Zirconia Esthetics Naturally, all Sculpture Studios Zirconia restorations use ZEN color infusion techniques to custom shade each restoration. This technique allows each restoration to be shaded with dentin, enamel and nuance colors to produce the most life like zirconia restoration possible, with ultimate esthetics. Restorations are pre evaluated to determine whether a thin facial application of ceramic is necessary for final esthetics. Then each restoration is hand polished to achieve maximum wear compatibility, translucency and natural esthetics.

The IPS e.max ZIRCAD zirconia system is the only zirconia system to share the IPS e.max® shade concept. The extensive zirconia options are integrated with IPS e.max to create an expanded all-ceramic system that integrates different materials into one system for many indications.

IPS e.max ZIRCAD discs are available in several translucencies, each of which is comprised of a variety of shades and thicknesses. An appropriate disc can easily be selected depending on the indication and esthetic or functional needs of the final restoration. With a wide range of processing options, the e.max ZIRCAD system offers the most comprehensive variety of solutions for the efficient and individual production of dental prostheses made of zirconium oxide.

IPS e.max ZIRCAD T is the best full contour zirconia option when durability is a must. It is ideal for long-span monolithic bridges and cases in which only minimal occlusal reduction is possible. Zenostar T provides the highest strength for full contour restorations in the Zenostar system.

Indications: include long span bridges, Implant supported bridges, Screw retained Implant bridges. (images)

IPS e.max ZIRCAD MT Multi
IPS e.max ZirCAD MT Multi is a new polychromatic zirconia from Ivoclar Vivadent. It is the most esthetic, high strength multi-translucent zirconia on the market, offering up to 30% higher flexural strength and 50% higher fracture toughness compared to other common translucent zirconia materials. IPS e.max ZirCAD MT Multi, has been designed with a special powder formulation which offers high biocompatibility and excellent flexibility. This pre-shaded medium translucency (MT) multi zirconium oxide was designed to be the ideal zirconia choice for cases in which high mechanical stability and natural looking dentition are of the essence.

IPS e.max CAD
IPS e.max CAD unites modern milling processing technology with a high-performance material. The lithium disilicate glass-ceramic is manufactured in an innovative technological process, unique in the dental industry. The glass-ceramic is processed for the laboratory in a crystalline intermediate phase. In this “soft” state, the material exhibits its unusual “bluish” color and strength of approximately 160 MPa. In this “blue” phase, the restorations can be manually adjusted or cut-back in a fast and efficient fashion. IPS e.max CAD acquires its final strength of 500 MPa and the desired esthetic characteristics, such as tooth color, translucency and brightness, during the crystallization process.
Indications: veneers, inlay-onlay, single anterior-posterior restorations.
