IPS e.max® is a lithium disilicate glass ceramic that has optimized translucency, durability, and strength for full anatomical restorations. IPS e.max® exhibits superior durability and features 360-400 MPa of flexural strength. Due to its high esthetics and strength, it is an affordable alternative to PFMs and layered zirconia-based restorations. The opalescence, translucency, and light diffusion properties of IPS e.max® were all designed to replicate natural tooth structure for beautiful and undetectable restorations. IPS e.max® is biocompatible and comes with a 5-year replacement-free warranty.Send a Case Download Rx
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.
