Bioactive Zirconia Denture
The invention discloses a biologically active zirconia denture has a gradient structure, the gradient structure consisting of a biomimetic nano-gradient biologically active outer surface layer, the nano-gradient outer surface layer is composed of zirconia nanocrystals and a plurality of nanopores penetrating gradiently through the layer, a micron-gradient biocompatible inner layer, the micron-gradient inner surface layer is composed of zirconia microncrystals and a plurality of micronpores penetrating gradiently through the layer, a dense micron-gradient biocompatible matrix structure, a uniform gradient transition is formed at the interface between the nano-gradient outer layer and the micron-gradient inner layer, and the micron-gradient inner layer and the matrix. The invention has the advantages of high strength, high toughness, low friction coefficient, low abrasion to the teeth, good biocompatibility and biological activity.
