OC and calcium concentration in culture medium (n = 6 for each group). a OC concentration in each group on day 8 and day 14. The comparison with non-coated PEEK (control group). There were no significant differences among the groups on day 8, but on day 14, the concentration of OC increased in all groups. Compared to the control group (non-coated group), the OC concentration was significantly higher in the SrHAP, SrSiP, and SrZnSiP groups on day 14. Data are shown as the mean ± SD. Asterisk indicates p < 0.05 vs. non-coated PEEK group. b Calcium concentration in each group on day 8 and day 14. The comparison with non-coated PEEK (control group). The concentration of calcium was determined on day 8 and on day 14. There were no significant differences among groups on the day 8, but the calcium concentration in the apatite-coated groups tended to decrease on day 14. Compared to the control group (non-coated group), the calcium concentration was significantly lower in the HAP, SrHAP, SrSiP, and SrZnSiP groups on the day 14. Data are shown as the mean ± SD. Asterisk indicates p < 0.05 vs. non-coated PEEK group
