“…Porcelain is used in aesthetic dentistry to realize cosmetic restoration [19][20][21] in the oral cavity to achieve an appropriate optical transparency. However, the requirements for porcelain are not purely cosmetic; it also needs to be sufficiently strong to withstand masticatory functions and to be durable.…”

Addition of platinum and silver nanoparticles to toughen dental porcelain

Several studies have investigated toughening porcelain that is layered over a frame or a core. The introduction of residual compressive stress to the surface of porcelain has been shown to be effective to strengthen it. In the present study, nanoparticles of precious metals of silver and platinum (rather than non-precious metals) were used to evaluate if they could increase the fracture resistance of porcelain. The addition of silver and platinum nanoparticles was found to improve the mechanical properties of porcelain since it increased both the Young's modulus and the fracture toughness of commercial porcelain.

The advancement of new technologies for the creation of biomaterials has been inspired by the demand for materials, capable of bearing new specifications and applications. Ceramic materials based on alumina (Al2O3) and zirconia (ZrO2) is used as material of choice for fixed dental prosthesis due to their excellent properties, such as strength, corrosion resistance and biocompatibility. Full coverage zirconia-based ceramic crowns with knife edge preparations can offer a good esthetic result with minimum tooth preparation combining strength and could be considered as a treatment option in selected clinical cases. All-ceramic frameworks are fabricated from zirconium oxide and veneered in the layering technique. Additional advantages of the zirconia based all ceramic restorations are the esthetic characteristics, the biocompatibility and durability. They also show increased abrasion resistance, color and contour stability, appropriate translucency and excellent tissue response due to minimal plaque accumulation.

“…The material is heated to a high temperature and pneumatically pressed and the resultant microstructure is similar to that of powder porcelains; however, less porous and a higher crystalline content is the main advantage of the final laminate porcelain veneer constructed from leucite system. Due to its favorable strength and shade, the manufacturer's instructions recommend its use for inlays, onlays, veneers anterior or posterior crowns and implant crowns (27)(28)(29)(30).…”
