Now, 3D-printed bone implant that dissolves in body

Press Trust of India | Moscow October 27, 2016

Scientists have developed a new type of 3D-printed polymeric bone implant with increased survival rate in body, as well as the ability to organically degrade and thus subsequently be replaced by natural bone tissues.

Researchers at National University of Science and Technology (NUST) MISIS in Moscow, developed the implant with shape memory that can be used without fittings and blocking devices during surgery.

One of the new implant's characteristics is increased implant survival rate in body tissues, and the ability to organically degrade and thus be replaced by natural bone tissues, researchers said.

"Young scientists from the Centre of Composite Materials at NUST MISIS have created the prototype of a new polymeric implant which is coarctate, so shielded from the mechanical impact of surgery, and it 'unfolds' at a certain temperature during the surgery," said Alevtina Chernikova from NUST MISIS.

"Therefore, the implant can be printed on a 3D printer at the selected dimensions, compressed twice in protective, biodegradable shelling, heated during the surgery and eventually become securely fixed into the renovated area of bone tissue without using metal blocking devices and fasteners traditionally used in transplantology," said Chernikova.
