The current ceramic systems in dentistry represent an alternative to metals in prosthetic treatment. However, these materials did not reach the same long-term results of conventional metal-ceramic prosthesis. In most cases, especially in anterior prostheses, the behavior of these materials is satisfactory. Nevertheless, as the demand for aesthetics requires the use of ceramics in the posterior regions, the rate of failure increases. Therefore, knowing what to expect of each material makes it possible not only to indicate or contraindicate the use of these prostheses, but also to develop new materials and techniques. The objective of this review was to explain the various ceramic systems and their mechanical behavior during the clinical use, reporting the locations, types and regions of most frequent failures in current systems in the search for solutions.
