Thermophysical modeling of novel machinable ceramic materials

Simulation of clinical fractures for three different all-ceramic crowns

Comparison of fracture strength and fracture modes of different all-ceramic crown systems is not straightforward. Established methods for reliable testing of all-ceramic crowns are not currently available. Published in-vitro tests rarely simulate clinical failure modes and are therefore unsuited to distinguish between the materials. The in-vivo trials usually lack assessment of failure modes. F...

Stress analyses applications on all-ceramic crowns with different designs

Different studies available in literature regarding the analysis of all-ceramic restorations failures, investigated several parameters involved on the tooth structure restoration complex, in order to improve clinical performances. Some of the parameters, like the framework design, are technique-sensitive during the manufacturing of the restorations and can easily influence the failure rates and...
