At Gnathodontics we are pleased to offer the latest pressable materials from Ivoclar Vivadent. IPS E.MAX PRESS
is a proven, high strength lithium disilicate pressable ceramic. The range of available shaded ingots allows
Gnathodontics to fabricate restorations with a high degree of translucency or maximum opacity for optimal masking
ability. This material, when used in its monolithic form, exhibits clinically proven strength and longevity for
For anterior applications, when combined with E.MAX Ceram porcelain, the material delivers the esthetics that we
have come to love and expect from Ivoclar’s original Empress Esthetic restorations but with the advantage of
increased strength. Our ceramists fabricate your anterior restorations very similar to the original IPS Empress
technique. The crowns are waxed and pressed with a cut back of the incisal one third so that we can layer
translucent porcelain to achieve the esthetics your patients’ require. The functional lingual surface is worked
out in wax, pressed and left in a monolithic state for maximum strength, thus combining the best of both worlds,
Beauty AND Strength!
When you send a case to Gnathodontics prescribing E.MAX in the posterior, you can always expect to receive a
crown that is fabricated in the monolithic form. Ivoclar’s studies show the material to have a flexural
strength of 400 MPA when pressed to full contour. We have consistently achieved outstanding results with this
technique and feel this should be the preferred method for fabrication of posterior crowns when using E.MAX
Press. Ivoclar’s studies have shown that the press technique has slightly higher compressive strength results
than the milled blocks. Our ceramists have the convenience of using one layering ceramic (E.MAX Ceram) when
fabricating crowns and veneers. This allows for greater control when fabricating combination cases.
(Please remember to include a stump shade with each E.MAX or EMPRESS case).
The high strength of IPS E.MAX lithium disilicate allows the dentist to choose between adhesive bonding
and conventional cementation techniques. Adhesive resins, such as Variolink, offer higher immediate bond
strength and better marginal seal and therefore are recommended in any clinical situation where proper
isolation can be achieved. A universal adhesive resin such as Multilink Automix, can also be used where
preps have proper retentive design and adequate material thickness. E.MAX is suitable for crowns,
veneers, inlays & onlays and 3-unit bridges for both anterior and posterior regions.
IPS Empress from Gnathodontics is the material of choice when esthetics matter equally with form, fit, and
function as the primary criterion in the treatment process. The IPS Empress System is suitable for single
units crowns, veneers, inlays and onlays. The Empress material's color and clarity have been enhanced,
resulting in improved and superior optical properties. New leucite crystal distribution makes Empress
restorations even stronger than before. The high fracture resistance, coupled with natural-looking aesthetics,
yields beautiful restorations for any area of the mouth.
