Result of push-out test for the RBM implant and MRI. a Representative force–displacement curves for the RBM implant after 8 weeks. b Representative force–displacement curves for the MRI after 8 weeks. c Maximum push-out forces required for the removal of MRIs and RBM implants. The graph plots the average maximum push-out forces of the MRIs and RBM implants after 4, 8, and 12 weeks (n = 6, ±SD). A repeated-measures analysis with ANOVA and Bonferroni post hoc test showed significant differences (p < 0.05), except between 4 and 8 weeks in the RBM implant group (p = 0.1188) and the MRI group (p = 0.1707)
