Nowadays, nanopowders and nanocomposites reinforced with nanofillers are the most rapidly developing group of materials with excellent prospectives for application in a wide range of industry and medicine. The aim of the paper is to present several examples of nanomaterials developed at the Faculty of Materials Science and Engineering of Warsaw University of Technology which can be used as dental materials.
Ceramic-polymer composites are the most popular materials used for dental fillings. The conventional composites are reinforced with ceramic powders with an average particle size ranged from a half to tens micrometers. Beside unquestionable advantages of composite materials, their properties, such as polymerization shrinkage and mechanical resistance, still need to be improved. The paper will discuss the influence of nanofiller addition on relevant properties of ceramic-polymer dental composites.
The other group of nanomaterials applied as dental materials is nanostructured yttria stabilized zirconium oxide ceramics. This ceramic is widely used for fabrication of crowns, bridges, inlays and other dental elements for which high strength, durability and esthetical appearance are required. The effect of nano-grain size of ceramic powders on the sintering parameters, microstructure and properties of zirconia ceramic will be discussed.
Finally, possibility to use of nano-titanium for the most loaded dental parts will be also presented.
