Bone healing can be stimulated by biological factors, chemical cues and even by an electrical field. Since electrical stimulation can improve bone healing after bone fracture, implants are being produced with charged surfaces for faster bone growth and better osteointegration. Previous work has focused on altering the electric field during polarization, but another approach is to identify the dipoles that present a charge and vary the concentration of charge generators. Thermally sprayed hydroxyapatite (HAp) contains dipoles, has a good biocompatibility, and so is suitable for this study. Hydrothermal treatment (HT) increases the depleted hydroxyl ion (OH-) concentration by incorporating OH- in the HA structure. In this study, we show how the OH- concentration influences the degree of polarization.
