Mg enhanced angiogenesis and coupled osteogenesis in MRONJ, which could be inhibited by blocking VEGF receptor-2 and CGRP receptor simultaneously, as indicated by micro-CT based angiography and bone histomorphometry analysis (A) Representative 3D reconstructed images of micro-CT based angiography showing the differences of vessel volume compared among the BP + Ti, BP + Mg, and BP + Mg + inhibitor/antagonist groups at 8 weeks after surgery. Scale bar: 5 mm (B) Quantitative analysis of angiography in different groups at 8 weeks after surgery (C) Representative 3D reconstructed images showing the differences of newly formed bone in the defect compared among groups at 8 weeks after surgery. Scale bar: 1 mm (D) Quantitative analysis of newly formed bone in different groups at 8 weeks after surgery. SU5416, VEGF receptor-2 inhibitor; BIBN, CGRP receptor antagonist. Column and bar indicate mean and SD, respectively. n = 4–5 for each group, by One-way ANOVA with Bonferroni post hoc test. ∗, p < 0.05; ∗∗, p < 0.01; ∗∗∗, p < 0.001.
