Post concepts are changing.

Use of post-and-core restorations has changed markedly in the past several decades. Current use and research supports techniques using tooth-colored, fiber-reinforced resin-based composite posts or titanium alloy posts cemented with resin cement, followed by resin-based composite build-ups. Although fiber-reinforced resin-based composite posts appear to be very promising, long-term clinical observation is needed. I have made suggestions about when to use posts, what type of post to use and how to use them.
