Zirconia vs. lithium disilicate

Ask Dr. Christensen - Dental Economics
Excerpt: Many of my patients prefer to avoid the use of metal in their mouths. I have suffered through the significant failures of many versions of all-ceramic restorations, and I'm not eager to try other all-ceramic restorations without sufficient positive research showing that they are working. There are many ads in dental journals about the newest form of all-zirconia tooth-colored indirect restorations. I think that concept was started by Glidewell Laboratories and is called BruxZir. All-zirconia restorations are advertised as excellent single- and multi-unit tooth colored restorations. What can you tell me about this newest unknown?
