Abstract
Hydroxyapatite(HA)-coated implant has a better biocompatibility than titanium and can lead to the biointegration between bone tissues and implants. Most of HA coated implants show porous structures on them due to the plasma coating. Little reports regarding cell behaviour on the porous HA has been shown. Therefore, the present study observed the morphological findings of the cells plated on the implant by SEM.
SEM observations showed porous structures on the surface of the implant and stratified structure on the cross section of it.
The osteoblast-like cells (MC 3 T 3-E 1) attached and spreaded well on the porous HA as well as smooth titanium. On the porous HA, the cells bridged among apical regions of the rough surface with numerous philopodia. The concept of the two-center effect might explain the bridging phenomenon.
