Yesterday (Dental Elf 14th Jan 2012) we looked at a review that compared cast and fibre posts in-vitro. Here we are looking at a trail that compares the use of more flexible, dentine-like (low Young modulus) glass fibre–reinforced epoxy resin posts (GFREPs) with rather rigid, stiff (higher Young modulus) titanium posts (TPs) in order to [read the full story…]
