Is dentistry ready for a CAD/CAM designed, industrial composite post and core?

In the past decade, dentistry has gone crazy for CAD/CAM design full coverage prostheses, and with a growing variety of  software, equipment  and ceramics to choose from,  the old standby PFM is dying a long slow death. The technology exists at this time to have CAD/CAM programs scan the inside of a flared, over-prepared root canal treatment, and drive machine to make a custom fitted “post core assembly”  from a block of multilayered multidirectional fiber reinforced composite, possessing mechanical properties similar to the remaining dentin.  It combines the low modulus, aesthetic, biocompatible approach with the ability to make something in one piece that is custom fitted like the old cast post core. 

With gold so expensive, and base metals under scrutiny  for biocompatibility and allergenic issues, is this the wave of the future?

Do fiber post actually re-strengthen weakened teeth?

In the 1980s, leading researchers and authors concluded for us that metal posts do not, after all, reinforce endo-treated teeth. When the original carbon fiber posts were introduced in the early 90s, and compared in vitro to metal posts, they demonstrated a much a lower predisposition to root fracture, owing to their mechanical properties. Ten years after that, there is a growing body of research indicating that properly placed in sized quartz fiber posts actually do reinforce and the endodontically treated teeth, compared to know post at all (composite alone) and, in clinical cases where fewer dentin walls remain, the benefit of the quartz fiber post placement is the most profound.
