IPS e.max

IPS e.max® is the most trusted all-ceramic solution available. This glass-ceramic is a lithium disilicate that is available as both a pressed and milled solution. It was specially formulated by Ivoclar Vivadent to ensure high esthetics and metal-free durability. IPS e.max® offers exceptional beauty and strength of up to 2.5 to 3 times more than alternative all-ceramics. These restorations can either be customized as a full-contour monolithic or cut-back and layered with porcelain for advanced lifelike esthetics.

  • Indications

    IPS e.max® can be used for veneers, inlays and onlays, occlusal veneers, partial crowns, minimally invasive crowns, implant superstructures, hybrid abutment solutions, and three-unit bridges up to the second premolar as the terminal abutment. 

  • Contraindications

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

  • Peparation

    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.

  • Cementation

    IPS e.max® may be cemented using a resin reinforced glass ionomer such as RelyX Luting cement. When a greater bond is needed do to the lack of a retentive preparation, use resin cement like RelyX Unicam or RelyX Ultimate.

  • Tech Notes

    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.).
