Indications & Recommendations

• Inlays
• Onlays
• Veneers to 0.4 mm thin
• Crowns
• 3-unit bridges to the 2nd bicuspid

We recommend a maximum pontic span of 0.9 mm in the posterior, 11.0 mm in the anterior, and an interproximal connector size of 16.0 square mm.

Preparation/Dentin Shade

Given the varied indications and translucency of the material, a preparation or dentin shade must be provided for optimal esthetic results. This is best communicated utilizing the IPS Natural Die Material shade guide by Ivoclar.

Production time is seven working days in the laboratory.

Cementation

Crowns may be bonded or conventionally cemented based on the material thickness of the finished crown. For restorations that meet the preparation criteria of a minimum 1.5mm occlusal thickness, conventional cementation is possible. If the minimum thickness is at all compromised adhesive cementation is advised. Note: Because studies have shown that adhesive cementation almost doubles the static load-bearing capacity of a lithium disilicate restoration, and gives your patient the most dependable product possible, our recommendation for all posterior restorations is adhesive bonding.

Production Time

Production time is seven working days in the laboratory.
