[Progress of research on fiber posts].
In the last few decades, casting metal has been the most commonly used post-core systems. But the elastic modulus of metal posts is higher than that of the dentin. Root fractures often happen because of the higher elastic modulus. The fiber posts can reduce or avoid root fractures because their elastic modulus is similar to that of the dentin. Therefore, they are widely used clinically to preserve tooth tissues and restore them after failure. This review article aims to introduce the recent research of the fiber posts.
