Side effects

  • If the patient is known to be allergic to any of the components of IPS e.max, the product should not be used to fabricate restorations.

Preparation Requirements

  • Shoulder margin, 1.2 mm to 1.5 mm facial reduction
  • mm reduction at the gingival margin
  • 1.5 mm incisal reduction
  • 1.2 mm lingual contact clearance
  • Rounded internal line angles
  • Football-shaped finishing bur for lingual reduction
Successful results can only be achieved with IPS e.max if the guidelines and framework thicknesses are strictly observed.

Anterior and posterior crowns
  • The anatomic shape is evenly reduced while observing the given minimum framework thickness.
  • A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°:
  • The width of the circular shoulder/chamfer is approx. 1.0 mm.
  • Reduction incisal or occlusal by approx. 1.5 mm.
  • The vestibular or lingual reduction is approximately 1.2 mm for anterior teeth and approximately 1.5 mm for posterior teeth.

  • It is of critical importance to use the fine or ultrafine diamond instruments for finishing and adjusting IPS e.max. If unsuitable grinding instruments are used chipping of the edges and local overheating may occur.
  • Only use fine or ultrafine diamond instruments, low rpms and light pressure to prevent delamination and chipping at the edges in particular.
  • Adjustments by grinding are carried out by irrigating with water, using fine-grained diamonds (<60 um) and/or fine, diamond-coated rubber polishers or silicon carbide rubber polishers.
  • Overheating of the glass-ceramic must be avoided to prevent fractures.

e.max layered cementation

The high strength of IPS e.max lithium disilicate offers dentists a choice to adhesively bond or conventionally cement their restorations.

Coordinated especially for Ivoclar Vivadent restorative materials, Ivoclar Vivadent recommends the following cements to maximize the performance and esthetics of IPS e.max restorations:

For maximum bond strengths and in situations where adequate retention is not possible in the prep design (e.g. veneers, inlays/onlays) adhesive cementation is recommended.

There are no minimum requirements for adhesive cementation. Adhesive cementation will provide higher-immediate bond strengths and a better marginal seal.

Self-adhesive resin cements combine an easy conventional cementation technique, with the advantages of "resin luting-composite"; increased strength, low solubility, high-level radiopacity and light-cure capabilities. Due to the lower bond strengths offered by this category of cements, it is strongly recommended that self-adhesive resin cements only be utilized in situations where a conventional cement would normally be used; retentive prep design, high-strength restoration with adequate thickness and tight fit.

For the cementation of IPS e.max restorations, you may choose from a selection of tried-and-tested adhesive luting composites and cements from the coordinated range of Ivoclar Vivadent products. The dual-curing self-adhesive Multilink Sprint luting composite is suitable for the cementation of IPS e.max restorations. In contrast to traditional luting composites, it contains an acidic adhesive monomer (MDP), which generates self-adhesion on enamel and dentin so that the additional application of primers on the preparation is no longer required.

Cementation of the IPS e.max restoration using Multilink Sprint

Procedure for the incorporation of IPS e.max restorations using Multilink Sprint:
  • Clean preparation, rinse with water, and dry with air.
  • Attach a new automix cannula to the double-push syringe before the application of Multilink Sprint.
  • Apply Multilink Sprint directly in the etched and silanated restoration.
  • Seat the restoration and remove excess cement (see Multilink Sprint Instructions for Use for detailed processing steps).

Patient Care

CARE INSTRUCTIONS Proxyt® — Professional care Like natural teeth, high-quality IPS e.max CAD restorations require regular professional care. This is not only beneficial to the health of the gingiva and teeth but also to the overall aesthetic appearance. You can care for valuable surfaces without abrasion using the pumice-free polishing paste Proxyt pink. The low RDA* value = 7 gives you peace of mind of cleaning with a low-abrasion paste. Scientific investigations and longstanding practical experience confirm the gentle effect compared to other pastes.
