IPS-e.max

IPS e.max

IPS E.max® CAD LT is a lithium silicate glass-ceramic uniquely designed for the manufacturing of one-piece, full contour metal-free restorations. It is manufactured with an innovative process, resulting in the exceptional homogeneity of the material. IPS E.max® CAD LT demonstrates the benefits of an all-ceramic restoration with the added flexibility of using adhesive bonding or cementation. It can be fabricated on either chamfer or shoulder tooth preparations. And because IPS E.max® CAD LT is not layered with porcelain, the risk of porcelain fracture is reduced relative to other glass ceramic materials.

 

IPS e.max press is indicated for full anterior or posterior crowns, veneers, inlays, onlays, as well as three-unit bridges having only one pontic with the second bicuspid as the most distal abutment.

Bridges which include molars, Maryland style bridges and bridges which have a short vertical height that does not allow for adequate connector height.

Anterior full-coverage crowns require a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Facial reduction is 1.5 – 2 mm; 1 – 1.5 mm lingual contact clearance. Incisal reduction is 1.5 – 2 mm with rounded internal line angles, and an incisal edge at least 1mm wide to permit optimum milling of the incisal edge during CAD/CAM processing.
Posterior full-coverage crown requires a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Occlusal reduction is 1.5 – 2 mm: axial reduction (buccal, lingual and interproximal) is 1.5 mm with rounded internal line angles.

IPS e.max layered – can be either cemented using a resin reinforced glass ionimer such as Relyx Luting cement. Or bonded using a resin cement, when extra strength is needed due to lack of retention on the prep, use a resin cement such as Relyx Unicem or Relyx Ultimate.

If adjustments are needed, use fine diamonds with water and light pressure. Always remove the crown when adjusting or bond/cement crown before adjustments are made.).
