Title:
BIOACTIVE ZIRCONIA DENTURE
Document Type and Number:
WIPO Patent Application WO/2019/011173
Kind Code:
A1
Abstract:
Disclosed is a bioactive zirconia denture, wherein same has a gradient structure, and sequentially comprises a bioactive outer surface layer and a substrate structure layer (3) from an occlusal outer surface to an adhesive inner surface; the bioactive outer surface layer is composed of an outer nano-pore layer (1) and an inner micron-pore layer (2); the micron-pore layer (2) is composed of zirconia nano-grains and a plurality of micron-pores penetrating through the micron-pore layer (2); the substrate structure layer (3) is composed of an outer dense zirconia nano-grain layer and an inner dense zirconia micron-grain layer; and the interface between the nano-pore layer (1) and the micron-pore layer (2) forms a uniform gradient transition, and the interface between the micron-pore layer (2) and the outer dense zirconia nano-grain layer of the substrate structure layer (3) forms a uniform gradient transition. The bioactive zirconia denture has the advantages of a high strength, high toughness, low friction coefficient, low abrasion to the antagonist teeth, good biocompatibility and bioactivity.
