Abstract

Introduction: Additive manufacturing or 3D printing are key methodologies to produce libraries of bone substitutes to test them to identify highly osteoconductive microarchitectures for bone defects or bone augmentation. Bone is a lightweight, high strength structure and resembles in its trabecular microarchitecture a gothic style. TPMS architectures are also lightweight and high strength. Therefore, we produced triply periodic minimal surface (TPMS) lightweight-based scaffolds based on three different algorithms and tested them in a cranial defect and a bone augmentation model in rabbits. 8 Methodology For the production of scaffolds, we applied the CeraFab 7500 from Lithoz, a lithography-based additive manufacturing machine and studied tri-calcium phosphate- based and hydroxyapatite-based scaffolds. As in vivo test model, we used a calvarial defect and a bone augmentation model in rabbits. Histomorphometry revealed that all generatively produced structures were well osseointegrated i...
