Microradiography of representative specimens of the different groups at specific time points (magnification = 2.5×). At early stage of bone healing up to 30 days after implantation there were only mild differences of bone regeneration visible among the three test defects (AD, PD, BM) and the control defect (CO). At day 60 and day 90 the area of newly formed bone inside the defect showed significant differences in comparison to control. (Reproduced with permission:[21]).
