Is Zirconia better than porcelain?
Zirconia offers superior strength and durability for dental crowns. It is at least three times stronger than porcelain or PFM restorations. Unlike porcelain, zirconia can withstand wear and tear without chipping, which is why zirconia restorations tolerate extreme chewing and bruxism.
Does zirconia need silane?
“Feldspathic porcelain and glass ceramics (like lithium disilicate) were glass containing. Therefore, some glass was selectively removed by etching with hydrofluoric acid. … Then a silane primer was used to chemically bond to the remaining glass. This won’t work with zirconia.
Which is more expensive zirconia or porcelain?
