A very esthetic all-ceramic option, this lithium disilicate glass-ceramic is highly customizable. It can be crafted as a full-contour monolithic or cut-back and layered with porcelain. This restoration provides lifelike esthetics due to four levels of translucency and is fracture-resistant with a strength of up to 500 MPa. This material is 2.5 to 3 times stronger than other glass-ceramic options. IPS e.max® also has additional impulse ingots for maximum translucency and opalescence. It is a reliable restorative solution that provides exceptional beauty and durability.
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 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 Ultimate.
The manufacturer Ivoclar Vivadent recommends using Multilink Automix for maximum strength of the restoration over-all.
If adjustments are needed, use fine diamonds with air/water spray and light pressure. Always remove the crown when adjusting. To polish the roughened surface use the Brasseler Dialite System or similar substitute.
