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
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 Imm 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 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
