IPS e.max Zirconium Oxide
High-strength zirconium oxide (ZrO2) really proves its worth in long-span bridges. It is one of the most efficient all-ceramic materials for dental-lab applications. IPS e.max zirconium oxide is distinguished for its excellent biocompatibility and limited heat conductivity.
The up to 12-unit bridge frameworks fabricated of IPS e.max ZirCAD are veneered with the highly esthetic IPS e.max Ceram layering ceramic or pressed over using IPS e.max ZirPress. IPS e.max ZirCAD frameworks may now also be used in conjunction with the high-strength IPS e.max CAD lithium disilicate glass-ceramic (LS2). In this context, an IPS e.max CAD veneering structure is fused to a zirconium oxide framework by means of an innovative fusion glass-ceramic.
With implant-retained restorations, the accuracy of fit of the high-strength, anatomically shaped Straumann® Anatomic IPS e.max® Abutment made of zirconium oxide is impressive. The homogeneous shade transition between the crown and the abutment convinces users with the desired IPS e.max esthetics.
Moreover, conventional inlay-retained bridges can be fabricated of an all-ceramic material using a minimally invasive procedure, which optimally combines the strength of the IPS e.max ZirCAD framework with the esthetics and accuracy of fit of the IPS e.max ZirPress press-on ceramic.
* The abutment is exclusively available from Institut Straumann.
The fluorapatite glass-ceramic ingots are indicated to press on IPS e.max ZirCAD and other ZrO2 frameworks with a CTE of 10.5 to 11.0.
IPS e.max ZirPress facilitates the working procedures especially for long-span restorations due to the detailed esthetic ceramic reproduction of the wax-up.
IPS e.max ZirPress ingots are available in three levels of opacity and in A-D and four Bleach BL shades. Moreover, two Gingiva shades are available. Since several ingots can be pressed in the IPS Investment Ring System together, they are available in only one size. Individual characterization or veneering is carried out using the IPS e.max Ceram Stains or layering materials.
HT ingots
Ingots featuring high translucency for the full-contour technique. The restorations are individualized using the IPS e.max Ceram Stains.
LT ingots
Ingots featuring low translucency for the cut-back technique. After the partial press-over, the incisal area is individually completed using the IPS e.max Ceram materials.
MO ingots
With the MO ingots (medium opacity), accurately fitting ceramic shoulders, bridge pontics and the cervical third are pressed before the restoration is layered to completion using IPS e.max Ceram.
Gingiva ingots
These two ingots facilitate the fabrication of the gingival portion of the restoration, especially in large (implant-retained) restorations, since the material does not shrink and the number of ceramic firings can be reduced.
For processing of IPS e.max ZirPress in the EP3000 and EP5000 press furnaces, the two investment materials IPS PressVEST and IPS PressVEST Speed are available.
