Summary of the histological outcomes of 3D-printed PCL and PLATMC templates implanted in the calvarial defect model (in rabbits). a histological micrographs (stained with Masson’s trichrome) at 4 and 8 weeks (scale bar = 200 µm) showing the interface of new bone with template strands. Note the direct contact (contact osteogenesis) of the new formed bone on PLATMC. b and c represents the quantitative histomorphometric analysis and bone contact (%) calculation, respectively. (F) represents fibrous connective tissues; (YELLOW dashed Line) represents areas of contact osteogenesis (present only at PLATMC); (NB) represents areas of new bone; (YELLOW double arrow) represents the characterized gap (fibrous connective tissue) at material/tissue interface (present only at PCL)
