Abstract

Polyetheretherketone (PEEK) has stood out as the leading high-performance thermoplastic for the replacement of metals in orthopaedic, trauma and spinal implant applications due to its high biocompatibility and mechanical properties. Despite its potential for custom-made medical devices, 3D-printed PEEK's mechanical performance depends on processing parameters and its bioinertness may hinder bone opposition to the implant. Concerning these challenges, this review focuses on the available literature addressing the improvement of the mechanical performance of PEEK processed through "fused filament fabrication" (FFF) along with literature on bioactivation of PEEK for improved osseointegration. The reviewed research suggests that improvements can be achieved in mechanical performance of 3D-printed PEEK with adequate FFF parametrization while different bioactivation techniques can be used to improve the bioperformance of 3D-printed PEEK. The adequate approaches towards these procedures can increase PEEK's potential for the manufacture of high-performance custom-made implantable devices that display improved bone-implant integration and prevent stress shielding of the treated bone.

用于高性能植入物制造的3d打印PEEK的机械性能和生物活性:综述。
聚醚醚酮(PEEK)由于其高生物相容性和机械性能,已成为骨科、创伤和脊柱植入物应用中替代金属的领先高性能热塑性塑料。尽管3d打印PEEK具有定制医疗设备的潜力,但其机械性能取决于加工参数,其生物惰性可能会阻碍骨与植入物的对抗。针对这些挑战,本文重点介绍了通过“熔丝制造”(FFF)改善PEEK机械性能的现有文献,以及PEEK生物活化以改善骨整合的文献。综述的研究表明,适当的FFF参数化可以改善3d打印PEEK的机械性能,而不同的生物活化技术可以改善3d打印PEEK的生物性能。适当的方法可以增加PEEK在制造高性能定制可植入装置方面的潜力,这些可植入装置显示出更好的骨-植入体整合并防止治疗骨的应力屏蔽。
