In Vivo and In Vitro Analyses of Titanium-Hydroxyapatite Functionally Graded Material for Dental Implants

Figure 6

Histological analysis of Ti-HA FGM dental implants in vivo. (a) (A, B) Images illustrate that the calcified tissues around the implant were immature (white arrow) and surrounded by vascular spaces. (C, D) Images obtained at week 8 exhibit a higher level of contact between the implant and the denser osseous structure. (E, F) At week 12 in the Ti group and week 8 in the Ti-HA FGM group, mature osseous tissue can be seen gradually surrounding the implant surface (green arrow). (b) From weeks 4–12, bone-implant contact (BIC) (%) increased faster in the Ti-HA FGM group than in the Ti group (, ). (c) The Ti-HA FGM dental implant exhibited higher BV/TV values (, ).
