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...
متن کاملVaried simulation-based stress analyses on zirconia all-ceramic crowns
The development of high-strength ceramics and its use in posterior areas has been a field of constant investigation. The performance of all-ceramic molar crowns fabricated with new CAD/CAM techniques is a subject of interest. The studies available in literature focused on the analysis of all-ceramic restorations failures, investigating several parameters involved on the tooth structure. The goa...
متن کاملToughening of CAD/CAM all-ceramic crowns by staining slurry.
The ability of staining slurries containing silver and/or potassium compounds to enhance the mechanical properties of a leucite-reinforced glass ceramic (IPS Empress CAD) was investigated by measuring the Vickers hardness, median crack length, toughness, and compressive residual stress of specimens. A staining slurry containing potassium ions was found to increase the toughness of IPS specimens...
متن کاملClinical marginal and internal gaps of zirconia all-ceramic crowns.
PURPOSE Marginal and internal gaps of NobelProcera crown zirconia were clinically evaluated using silicone materials. MATERIALS AND METHODS Ninety-one crowns were examined before final cementation, and white and black silicone materials were used to record the marginal and internal fit. The silicone materials were sectioned bucco-lingually and mesio-distally, and the thickness of the silicone...
متن کاملSimulation 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...
