IPS e.max® is a lithium disilicate glass-ceramic. It is the most esthetic of any all-ceramic option and is highly customizable. IPS e.max® 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. The innovative lithium disilicate is 2.5 to 3 times stronger than other glass-ceramic options. This product also has additional impulse ingots for maximum flexibility. It is a reliable restorative solution that provides extreme beauty, longevity, and durability. With its high flexural strength the risk of fracture is minimal and the need for chairside adjustments is low.Send a Case
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.
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.
