The IPS e.max crown is a revolutionary restoration that offers outstanding esthetics and strength. Made of lithium disilicate, it is incredibly strong and beautiful, perfect for restoring beautiful smiles to even the most discerning patients.
The IPS eMax is a premium lithium disilicate, glass-ceramic restoration. Combining lifelike materials and fracture resistant properties it offers durable beauty for anterior esthetics or posterior function alike! The flexibility of its composition makes this an excellent restorative method in any case--especially when you need to heal quickly while still looking natural .
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.
The IPS e.max layered surfaces can be bonded using a resin cement when extra strength is needed due to lack of retention on the prep, such as RelyX Unicem or Ultimate Cements are best for this application.
If adjustments are needed, use fine diamonds with water and light pressure. Always remove the crown when adjusting or bonding/cementing a new one before any changes are made so as not to compromise its durability and beauty in future wearings!
