Streaming - Onlays vs. Crowns
Gordon J. Christensen, DDS, MSD, PhD
What part of a posterior tooth is usually the most destroyed by caries? Of course, the MOD portion. What part do you cut away for a crown? The facial and lingual portion. Does this make any sense? Let’s do onlays that leave the facial and lingual tooth structure intact! The materials for tooth-colored onlays are now EXCELLENT! Lithium disilicate (IPS e.Max) and others now dominate the onlay concept. These are now well proven, strong, and unbelievably esthetic materials. They can be easier to accomplish than crowns and their esthetic qualities can last LONGER than crowns. Large class II resins are NOT lasting long, but onlays do last a long time, and third parties will now share on costs!
The following topics are included in this presentation:
- Making onlay tooth preparations easy and predictable
- Supragingival vs. subgingival margins
- Obtaining optimum retention for onlays
- Bases and liners
- Laboratory made or in-office CAD/CAM?
- Desensitizing tooth preparations
- Cementation and finishing onlays
- Repair and follow-up for onlays
- Practice management concepts—why a patient should want onlays
The live demonstrations of onlays in this presentation will make you want to do more of them.
