Other crown types typically need to be thicker to provide proper support. Conclusion: There are a multitude of alloys available and the selection of a particular alloy over another depends on several factors including cost, handling, physical properties, biocompatibility.

All-ceramic's certainly don't have the same long-term track record for longevity and durability as all-metal and PFM crowns do.
