Development of a 3D polyetheretherketone structure that mimics the cranial bone morphology for use in cranioplasty

Cranioencephalic traumatism (TBI) is a common situation in trauma hospitals and has become responsible for high rates of mortality worldwide. When the victim TBI affected by injuries to skullcap with need grafting, problems regarding availability suitable affordable materials eventually happen. In this study, 3D structure Polyetheretherketone (PEEK) that mimics cranial bone morphology use cranioplasty was developed. Samples different formulations, form round bars, were obtained through uniaxial compression, porosity controlled salt leaching technique. Then, specimens characterized terms pore distribution, surface roughness, compression resistance cytotoxicity. Results exhibited levels similarity strutures PEEK natural human bone, which indicates effectiveness proposed method mimicking compact/porous/compact system (diploe).
