Abstract
A new alloplastic high-permeable material based on tricalcium phosphate with Kelvin architectonics created by stereolithographic 3D-printing was studied in vivo. A monocortical defect of the femur was modeled in rats and the material was implanted into the defect area. In 24 weeks, the animals were euthanized and histological examination of the defect area was performed. One femur fracture with fixator migration was recorded after implantation of the studied material and the reference chronOS synthetic material. The studied material demonstrated better osteoconductive properties then traditional osteoplastic material, which was seen from greater number of bone trabeculae and their area in the defect area.
