Title:
DENTAL IMPLANT WITH EXCELLENT ANTIBACTERIAL PROPERTIES AND ANTIBACTERIAL COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/128360
Kind Code:
A1
Abstract:
Disclosed is a dental implant comprising: a titanium substrate; and a silver-titanium oxide matrix coated on at least a portion of the surface of the substrate, wherein the silver-titanium oxide matrix has a binding energy peak P1 of 570 to 580 eV and a binding energy peak P2 of 360 to 375 eV measured by XPS, and wherein an intensity I1 of P1 and an intensity I2 of P2 satisfy the formula below. 2*I1 ≤ I2 ≤ 5*I1.
