3D printing is quickly becoming an integral part of the implant industry, where it is taking over business with custom-made and unique 3D printed implants. However, even these are not magical solutions. Though they provide a much better fit, they are still followed by months or even years of painful rehabilitation. To make matters worse, material rejection is still a real danger. But now this issue is being tackled by 3D printing, as a team of Mexican researchers from the Autonomous University of Puebla (BUAP) has developed a new synthetic 3D printable biomaterial that completely mimics bone structures and facilitates bone regeneration.
This BUAP innovation has been pioneered by a group of researchers lead by Efrain Rubio Rosas, from the University Center of Entailment and Technology Transfer. As he explained, this biodegradable material is made from various degradable polymers and hydroxyapatite – a mineral commonly found in the body. “The human bone is composed of organic material such as collagen, proteins and growth factors, and other inorganic materials such as calcium phosphate and hydroxyapatite crystals. These are synthetically obtainable and, when used in orthopedic implants, are not rejected by the body,” he explained.
This makes it an especially attractive option for implants and for the replacement of small portions of bone tissue.
