Factors essential for successful all-ceramic restorations.
TLDR
Clinicians should choose appropriate all-ceramic restorations on the basis of their patients' needs, and zirconia-cored crowns are the strongest all- Aceramic system and may provide improved esthetic results compared with metal-ceric crowns.Abstract:
Background The use of all-ceramic crowns is increasing, and this trend will continue. However, all-ceramic systems are not all the same. They differ considerably in their relative esthetic potential, their physical properties and evidence base relative to longevity. The use of an all-ceramic system does not guarantee outstanding esthetics. Conclusions Some all-ceramic systems can provide superior esthetic results compared with metal-ceramic restorations. Zirconia-cored crowns are the strongest all-ceramic system and may provide improved esthetic results compared with metal-ceramic crowns. No all-ceramic restoration has been shown to have a life span equivalent to that of metal-ceramic restorations. Further clinical trials are needed. Practice Implications Clinicians should choose appropriate all-ceramic restorations on the basis of their patients' needs. Currently available evidence indicates that clinicians should not use all-ceramic crowns on molars; in addition, posterior fixed partial prostheses fabricated with all-ceramic materials have a high likelihood of failure.read more

From porcelain-fused-to-metal to zirconia: clinical and experimental considerations.
TL;DR: The use of zirconia frameworks for long-span fixed partial dentures or for implant-supported restorations is currently under evaluation and further in vivo, long-term clinical studies will be needed to provide scientific evidence for drawing solid guidelines as discussed by the authors.

TL;DR: Zirconia offers sufficient stability as a framework material for 3- and 4-unit posterior FPDs and the fit of the frameworks and veneering ceramics, however, should be improved.

The effect of surface grinding and sandblasting on flexural strength and reliability of Y-TZP zirconia ceramic.
TL;DR: The results indicate that sandblasting may provide a powerful technique for strengthening Y-TZP in clinical practice and grinding may lead to substantial strength degradation and reduced reliability of prefabricated zirconia elements, therefore, sandblasted of ground surfaces is suggested.
