The crown reconstruction of root canal-treated teeth admits different treatment options. What is the best suitable option and how the decision is made may always be disputed and even controversial? But the decision needs critical evaluation as the Restorative factor is considered as one of the most common reasons (44%) for extraction of endodontically treated teeth. On one hand, a full crown is considered to be the primary and oldest solution to improve tooth survival, and on the other, new materials and techniques help us in exploring new conservative treatment options which are also durable and aesthetically acceptable. This lecture intends to provide an insight about these new innovative direct post endodontic restorations with the incorporation of glass fiber mesh, which is based on understanding the biomechanical properties of Dentino Enamel complex and physicomechanical properties of the resin-based composite including the stress generated from both polymerization shrinkage and occlusal forces. Thus, stress-reducing long-term direct composite restorations for non-vital teeth as an option have been evaluated in the course.
