IPS e.max®

IPS e.max® Product Description

With over 100 million restorations, IPS e.max data shows over 97% survival rate and longitudinal evidence proves e.max to have a flexural strength of 500 MPa. IPS e.max restorations provide strength as well as beautiful results for your patients.

IPS e.max provides outstanding esthetics and precision marginal accuracy in both pressed and CAD/CAM milled applications, as well as the same flexural strength of 500 MPa. Additionally, e.max wear rates and natural esthetics are unequaled by any other monolithic restoration. E.max also has tooth-like fluorescence, opalescence, and an enamel-like translucency. The unique lithium disilicate framework is indicated for single anterior or posterior crowns, and strong enough for anterior 3-unit bridges (which includes premolars). IPS e.max restorations can be cemented with low-expanding resin-modified glass ionomer cements or bonded with resin cements.

IPS e.max is available as monolithic or layered restorations.

Key Features

• IPS e.max is strong, with flexural strength of 500 MPa
• Ideal for cosmetic cases, even in monolithic application e.max exhibits natural translucency that mimics enamel.
• Can be “micro” layered in cases where function requires extra strength of monolithic, but esthetic demands need increased cosmetic results.
• No allergy potential or irritation of tissue.
• Low thermal conductivity provides greater comfort for your patient.

Indications for Use

• Crowns, and bridges up to 3 units, with total lengths up to 14mm pontic span, or single crowns for all positions in the mouth.
• IPS e.max can be layered or monolithic, depending on the desired results.

Contraindications

Not recommended for posterior bridges or anterior bridges over 14 mm pontic span

Clinical Handling

Preparation

• 1mm shoulder margin
• 1.5mm axial wall reduction
• 2mm incisal/occlusal reduction required.
• No knife-edge margins
• Note: As with any all-ceramic, no sharp or right angles.

Cementation

IPS e.max® can be bonded using adhesive systems with dual cure resins, or cemented using low expansion cements, like resin-modified glass ionomers.
