Porcelain restorations can be fabricated in a range of shades and translucencies that, with esthetics and chemical resistance, make them almost ideal replacements for lost hard tissue. Further, being a good thermal insulator, porcelain protects the pulp against heat insult even with marked hard tissue loss.
Limitations of porcelain were indicated in Chapter 39. Despite improvements that are possible by control/>
