Bioactive ceramic-reinforced composites for bone augmentation [PDF]

open access: yes, 2010
Biomaterials have been used to repair the human body for millennia, but it is only since the 1970s that man-made composites have been used. Hydroxyapatite (HA)-reinforced polyethylene (PE) is the first of the ‘second-generation’ biomaterials that have ...
