Sistemas cerámicos puros parte 1: una evolución basada en la composicíon

The continuing advances in technology, dental materials and equipment have contributed significantly to improve the level of esthetic dentistry today. Among these innovations, development of pure ceramic restorations has evolved to give different alternatives. Dental ceramics have presented a rapidly technological changing to improve mechanical and optical properties. Currently there are several systems of metal free ceramics with excellent mechanical and optical properties, for making crowns and plurals. These modern systems are presented with various compositions and different preparation techniques, making these more versatile. Within this perspective, the dental market offers a huge range of new indirect and metal-free materials for prostheses, providing new options, plus also new questions to decide among the available alternatives. The aim of this review is take a view of the different ceramic systems in terms of its composition and different techniques of production.
