Monolithic Materials Masterclass: Working With Lithium Disilicate and Zirconia
PFM’s now make up only 10% of the crowns fabricated by the largest dental lab in the U.S., having been largely replaced by solid zirconia and lithium disilicate. These monolithic restorations are high-strength, cementable, allceramic restorations behave differently than traditional restorations, and this
session focuses on how to prep, adjust, de-contaminate, cement/bond, and cut off these new restorations when necessary. Perhaps most impressively, the fracture rates for these monolithic restorations are second only to cast gold.
- Be familiar with the strengths and weaknesses of monolithic and bi-layered restorations, especially including indications, contraindications and prep design.
- Learn the different types of zirconia oxide restorations and their indications, and why polished zirconia is preferable to glazed zirconia.
- Be prepared to de-contaminate these restorations, select the correct primers, and determine the most appropriate cement.
- Learn how to adjust contacts and occlusion, learn the safest way to cut off these restorations, and be familiar with the specialty burs and polishers for these restorations.
- Understand which monolithic materials are more appropriate as a veneer material and understand the relationship between flexural strength and esthetics.
