Posts were designed to retain the coronal restoration when inadequate tooth structure remained, for reinforcing endodontically treated teeth. Metallic posts being more rigid than the tooth structure undermines its usage. Due to the forces there could be differential movements of the components and the tooth, resulting in their separation or fracture. The metallic posts have aesthetic shortcomings especially when the newer all ceramic materials are used for restoring the anterior teeth. The growing demand for esthetic restorations in dentistry has led to development of tooth-colored, metal free post systems like carbon fiber posts, zirconia posts, glass fiber posts [translucent quartz fiber] and woven fibers[polyethylene fibers]which are discussed in this article.
