IPS e.max®

GCD Dental Laboratory is Colorado’s most experienced and skilled IPS e.max® laboratory. Our technicians have pressed well over 40,000 units. We have the distinction of having two genuine Ivoclar e.max presses, which is required in the fabrication of the IPS e.max Multi ingot. Wax margins are done by hand under a microscope after milling to ensure every restoration meets our high-quality standards.

IPS e.max® is made out of a highly esthetic lithium disilicate glass-ceramic. It can be fabricated as a full-contour monolithic or cut-back and layered with porcelain for anterior esthetics, making it a highly customizable restoration. Prescribe IPS e.max with confidence due to its flexural strength of 500 MPa and fracture-resistance.

IPS e.max®

Indications

IPS e.max is the premium lithium disilicate, glass-ceramic restoration. Combining lifelike materials and fracture resistant properties, IPS e.max is as durable as it is lifelike. The flexibility of IPS e.max makes it an excellent restorative method for anterior esthetics or posterior function.

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 can be 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.).
