E.max All-Ceramic System: Press/CAD/Promax
IPS E.max
At The Tooth Studio we were one of the first to order and work with the IPS E.max system.
E.max provides the ultimate in metal-free esthetics, producing exceptionally beautiful restorations virtually indistinguishable from natural teeth while still providing ample structural strength for all indications.
E.maxPress/CAD is the lithium disilicate core: stained monolithically or veneered with the E.maxceramveneering porcelain, E.max press/CAD comes in a variety of opacities and translucency dependent on the restorative intricacies.
The Hue, Chroma and value of the stump or tooth preparation, are vital in us utilizing the correct ingot to match the natural dentition.
ProMax™ is a trademarked term that is the combination of E.maxceram or Zirpress on Procera™ Zirconia, which combines the expertise of both systems to achieve unbelievable results.
E.max® Ceram is a Nano-Fluor Apatite Glass Ceramic, which mimics the optical effects of natural enamel, creating natural esthetics.
So all you would need for an E.max all ceramic case is E.max Press for lithium disilicate core or Promax™ if you want a zirconia core. Both options are indicated all over the mouth and are strong enough for any indication.
The Natural Die Material shade guide helps by disseminating the color from the clinic to the laboratory.
Normally, the choice of material mainly depends on aesthetic factors, but with IPS E.max, this strategy changes. Only the mechanical strength which the individual clinical situation demands needs to be taken into account, as comparable esthetics are achieved irrespective of whether zirconium oxide or lithium disilicate is employed.
IPS e.max Press Impulse
In pursuit of nature
IvoclarVivadent’s IPS e.max Press ingots are now also available as Impulse ingots. They are offered in three different brightness values and two opalescent shades.
The IPS e.max Press Impulse ingots in Value shades allow different brightness effects to be reproduced. They are used in the fabrication of partial crowns, single crowns as well as bridges. No matter whether a specific tooth shade needs to be created based on a defined brightness value, or consistent brightness needs to be established throughout restorations with different core shades, the Value shades enable restorations to be fabricated that blend in seamlessly with the remaining dentition. The desired tooth shade is finally attained by means of the staining or cut-back technique.
Lifelike opalescent effect
In the fabrication of veneers, particularly thin veneers, translucency and opalescence play a role that is equally important to that of the tooth shade in order to attain the desired optical effects. With the two new IPS e.max Press Impulse Opal ingots, the opalescent effect of natural teeth can be reliably mimicked, which is particularly desirable when fabricating anterior veneers.
Lithium disilicate-based
Like the time-tested IPS e.max Press ingots, which are offered in the levels of translucency HT, LT, MO and HO, the new IPS e.max Press Impulse ingots consist of lithium disilicate glass-ceramic material which features a flexural strength of 400 MPa.
IPS e.max Press Impulse Value 1, 2 and 3 as well as Opal 1 and 2 will be available from September 2010 onwards.
IPS e.max Press
IPS e.max Press are lithium disilicate glass-ceramic ingots for the press technique.
The innovative IPS e.max Press lithium disilicate glass-ceramic (LS2) offers excellent fit, form and function combined with high strength of 400 MPa. The material is supplied in four levels of translucency and two sizes. The resulting restorations exhibit lifelike esthetics, independent of the shade of the preparations.
IPS e.max Press is used to produce single-tooth restorations, bridges for the anterior and premolar region and implant superstructures. Minimally invasive inlays and onlays (1 mm) and thin veneers (0.3 mm) round out the indication range.
The two investment materials IPS PressVEST and IPS PressVEST Speed are available for processing IPS e.max Press.
A wide selection of ingots is offered from which users can choose the one that suits their preferred processing technique (staining, cut-back or layering technique) and the case at hand (e.g. discoloured preparation). The restorations are characterized or veneered with matching staining materials or layering ceramic from the IPS e.max Ceram assortment. The press material for the fabrication of full-contour restorations is available in 16 A-D and four Bleach BL shades. The materials for the layering technique are supplied in group shades.
Available ingots
HT ingots
The high translucency ingots (HT) are suitable for the fabrication of minimally invasive full-contour restorations, such as inlays, onlays and veneers. The restorations are characterized with staining materials.Press HT is suited for laboratories to create minimally invasive veneers pressed as thin as 0.3 mm.
LT ingots
Full-contour partial crowns and crowns are fabricated with the low translucency ingots (LT). In the anterior region in particular, the esthetic appearance of the restorations is maximized by employing the cut-back technique.
MO ingots
The medium opacity ingots (MO) are used to fabricate substructures for vital or slightly discolored teeth. They create an ideal basis for lifelike restorations completed with the layering technique.
HO ingots
In cases where the prepared tooth structure is discolored or titanium abutments are used, the HO ingots mask the dark background to achieve highly esthetic results.
IPS E.max CAD
IPS e.max CAD is a lithium disilicate ceramic block. The lithium disilicate ceramic (LS2) is user-friendly and provides esthetic results.
IPS e.max CAD is designed for fabricating esthetic, high-strength single-tooth restorations, such as veneers, inlays, partial crowns and crowns, by means of the efficient CAD/CAM technology. These restorations may also be conventionally cemented.
The ceramic is milled in a "soft" intermediate state in which it exhibits its characteristic, unusual bluish colour. In this state, the material can be manually adjusted or cut back in a few quick and easy steps and the fit can be checked.
Subsequently, the material is easily and quickly crystallized at approximately 850 °C / 1,562 °F (20-30 minutes). In this process, IPS e.max CAD acquires its final strength of 360 MPa and the desired esthetic properties, such as tooth shade, translucency and brightness.
IPS e.max CAD blocks are available in three levels of translucency and in two sizes. The LT and HT blocks for full-contour restorations are provided in 16 A-D shades and four Bleach BL shades. The MO blocks for the layering technique are available in group shades.
Available blocks
HT blocks
These new highly translucent (HT) blocks are used to machine minimally invasive full-contour restorations, for example inlays, onlays and veneers. These restorations are subsequently characterized with staining materials.
LT blocks
These blocks showing low translucency (LT) are suitable for fabricating full-contour partial and full crowns. The cut-back technique and subsequent layering with IPS e.max Ceram produces enhanced esthetic results in anterior restorations.
MO blocks
Because of their high opacity, IPS e.max CAD MO blocks are used to produce frameworks that are placed on vital and slightly discoloured prepared teeth. The frameworks are veneered with IPS e.max Ceram.

IPS e.maxZirPress
IPS e.maxZirPress are fluorapatite glass-ceramic ingots suitable for pressing onto zirconia frameworks.
The fluorapatite glass-ceramic ingots are indicated for pressing onto ZrO2 frameworks exhibiting a CTE of 10.5 to 11.0.
The fabrication of long-span bridges is made much easier by IPS e.maxZirPress, due to the faithful reproduction of the waxed-up model in ceramic.
The press-on technique efficiently produces zirconium oxide-supported (multi-unit) bridges, inlay-retained bridges, crowns and implant superstructures. In addition, this technique enables gingival parts to be reproduced and ceramic material to be pressed to abutments. The two investment materials IPS PressVEST and IPS PressVEST Speed are available for processing IPS e.max Press and IPS e.maxZirPress.
IPS e.maxZirPress ingots are supplied in three levels of opacity in A-D shades and in four Bleach BL shades. In addition, two gingiva shades are available. As several ingots can be pressed at the same time in the IPS investment system, they are supplied in only one size. The restorations are characterized with the staining materials or veneered with the layering materials from the IPS e.max Ceram assortment.
HT ingots
The ingots with high translucency are used for the full-contour technique. The restorations are then individualized with the IPS e.max Ceram stains. Even inlay-retained all-ceramic bridges can be fabricated with mimimal time and effort.
LT ingots
The ingots with low translucency are suitable for the cut-back technique. After the semi-anatomical pressing onto the framework, the incisal area can be individually characterized using the IPS e.max Ceram materials.
MO ingots
The MO ingots (medium opacity) are used to press accurately fitting ceramic shoulders, bridge points and the cervical third, before the restoration is completed using IPS e.max Ceram.
Gingiva ingots
These two ingots facilitate the fabrication of the gingival area, particularly in large (implant-retained) restorations, since the material does not shrink and thus the number of ceramic firing cycles can be reduced.
E.Max Cementation
IPS e.max restorations are flexible with regard to their cementation requirements. Crowns and bridges can be cemented according to adhesive, self-adhesive and conventional methods. Inlays and veneers are placed with the adhesive technique as usual.
Variolink II / Variolink Veneer
The dual-curing, highly esthetic luting composite Variolink II has been successfully used for more than ten years and produces excellent clinical results. The light-curing Variolink Veneer material is especially indicated for the cementation of veneers.
Multilink Automix
The universal luting composite offers a wide range of indications. Furthermore, it generates a very strong bond on all material surfaces. Multilink or Metal/Zirconia Primer is used for optimum bonding results.
SpeedCEM
SpeedCEM simplifies and speeds up cementation procedures and eliminates the need for separate conditioning with phosphoric acid and bonding.
IPS Natural Die Material
The light-curing IPS Natural Die Material simulates the shade of the prepared tooth and thus represents the optimum basis for true-to-nature shade reproduction of the given oral situation when fabricating all-ceramic restorations.
