Abstract
'A high-strength coating for dental and orthopedic implants utilizing hydroxyapatite (HAp) nanoparticles provides for a high level of osseointegration through a range of surface pore sizes in the micro- to nanoscale. Zinc oxide (ZnO) nanoparticles may be incorporated with the HAp nanoparticles to form a composite coating material, with ZnO providing infection resistance due to its inherent antimicrobial properties. A textured surface, consisting of "islands" of roughly square coating structures measuring about 250 .mu.m on a side, with spacing of 50-100 .mu.m therebetween, may further promote the osseointegration and antimicrobial properties of the implant coating.
