Document Type and Number:
WIPO Patent Application WO/2016/202100
Kind Code:
A1
Abstract:
Disclosed is a polyether ether ketone/nano-hydroxyapatite dental implant consisting of a neck (1) and a root (2), the neck (1) of which is grafted with a fibronectin or a basic fibroblast growth factor, and the surface of the root (2) of which is a micron porous-nano bulge multistage microstructure. The method for manufacturing the dental implant comprises: preparing a workblank; grafting the fibronectin or basic fibroblast growth factor onto the surface of the neck (1) of the workblank; the root (2) of the workblank is immersed in a decafluoronaphthalene solution for etching, and then put into nano-hydroxyapatite powder to adhere a layer of nano-hydroxyapatite particles; and the workblank is immersed in the nano-hydroxyapatite slurry doped with Ag+ or Zn2+. The elastic modulus of the dental implant matches a human bone tissue, and the dental implant has a high biological activity and continuous antibacterial capacity, thereby improving the long-term success rate thereof.
