Polymer-Infiltrated-Ceramic-Network the Evolution of CAD/CAM Materials

The development of dental materials during the last few years is related to many factors, such as patient aesthetics requirements and also the increase in usage of CAD/CAM technology. The literature review shows the most used classes of indirect restorative materials and it demonstrates how the evolution of metal-free materials has reached a new level. Research combined with manufacturing technology is focusing in creating a material with similarities to a natural tooth. However, some clinical aspects must be considered such as patient requirements, clinical cost, clinical performance, manufacturing process, developing procedure, and disposal concerns. It is clear that progress has been made in this field, with fracture load rate of different materials similar to each other. Nevertheless, the survival rate achieved is not yet enough to say that polymer-infiltrated-ceramic-networks are compatible with all-ceramic crowns.
