In a major step towards improving
surgeries after head or face injuries, scientists have developed a new type of
3D-printed polymeric bone implants that can survive in the body for long
periods and be subsequently replaced with natural bone tissue in the body. The implant
is coarctate and thus shielded from the mechanical impact of surgery, and it ‘unfolds’
at a certain temperature during the surgery. Researcher said that the implant could
be 3D printed at the selected dimensions, compressed twice in protective,
biodegradable shelling, heated during the surgery and eventually fix into the
renovated area of bone tissue without using blocking devices and fasteners used
in transplantology. Researcher has applied the shape memory effect in a
polymeric composite material based on polylactide. Researcher have developed a
technology stacking multi-potent mesenchymal stromal cells, a bioengineering
structure isolated from a patient’s bone marrow, which stimulates the formation
of blood vessels and tissue inside the implant, thus optimizing the process of
survival and increasing the efficiency of transplantation.
