In Vitro Mechanical Tests for Modern Dental Ceramics

The fracture resistance of all-ceramic restorations is one of the major concerns in clinical applications of these materials. before initiating a time-consuming and costly clinical investigation, an in vitro study can help to estimate the in vivo usability of a new dental material. mechanical properties of all-ceramic materials are frequently evaluated to predict their clinical performance. since the test methods have influences on the obtained results and mechanical behavior of ceramic materials, the differences between different methods and techniques should be well recognized. the aim of this review article was to briefly appraise mechanical test methods usually use to evaluate dental ceramic materials, and to discuss their clinical implication and limits in dentistry. the search was limited to pubmed and only available and the most relevant sources were included.
