Comment:

This article suggests that all types of all ceramic crowns "are weaker than PFM [porcelain fused to metal] crowns, even when properly bonded and cemented with resin cement."

Abstract / Excerpt:

“Often, claims about AC [all ceramic] crowns made by clinicians, manufacturers and laboratories are overly optimistic, causing disappointment and frustration for practitioners and patients when failure occurs. What is the state of the art for AC crowns? This article presents the most popular brands of AC crowns, their advantages and disadvantages, indications and contraindications, and suggestions for the future.”
