Which crown goes where?

Will zirconia continue to dominate indirect restorative dentistry?

Dr. Gordon Christensen offers his advice about the current types of zirconia and the new crown materials on the market.

I have not had problems with the older materials, especially porcelain-fused-to-metal (PFM), or with the newer material, Glidewell’s BruxZir. Can you give me some guidance?
