Today, it is undisputed that root posts made of glass fiber offer advantages for a permanently stable root structure, such as a dentin-like elastic modulus to minimize the risk of root fractures. In addition, root canal revision – if the worst comes to the worst – is easy compared to titanium posts.

However, in 1995, when E. HAHNENKRATT GmbH was the first company in Germany to offer trend-setting carbon fiber root posts, all established manufacturers continued to rely on titanium root posts. There was great interest from universities in 1995 after the introduction of Composipost, but for many it took decades to revise entrenched conventional views. In 1998, a dissertation at the Charité Medical Faculty of the Humboldt University in Berlin still concluded that the application of a post made of fiber-reinforced composite in combination with the use of dual-curing composites was many times more expensive than insertion of a titanium post with the aid of zinc phosphate cement.*) Today, the use of composites and glass fiber root posts is standard practice.
