“…Currently, additive manufacturing allows production of custom prosthetic implants, fitting them directly to patient needs. It can be used in many medical specialties including neurosurgery, maxillofacial surgery, craniofacial and plastic surgery, oncology, dentistry and orthopedics [3][4][5][6][7][8] . The main metallic materials used in orthopedic implants are stainless steel alloys, cobalt-chromium alloys and titanium alloys 1,9,10 .…”

“…AM production and implantation of basic personalised implants based on XCT data are now commonplace, and reflecting this, a wide array of studies involving implantation have been published over the past year as the technology has become better understood [106][107][108][109][110][111][112][113][114][115][116][117][118][119]. Clinical usage of metallic implants produced by AM in particular is now becoming common, specifically in maxillofacial and orthopaedic applications, though a number of issues remain preventing further adoption.…”

“…As demonstrated in the latter study by Haefeli et al [119], XCT based implants are now increasingly used in humans, and further examples of implantation are presented elsewhere [107][108][109]111,115,118]. A particularly common application remains in cranio-maxillofacial surgery, and Jardini et al [107], Radovan et al [108] and Cho et al [118] present case studies involving the implantation of devices to replace various skull defects, produced using metallic powder bed fusion with XCT data.…”

These authors all concluded successful results of shorter surgical times, as well as higher accuracy implant production compared to traditional production methods, confirmed using postoperative XCT.…”

Abstract. The use of X-ray computed tomography (XCT) with additive manufacture (AM) within a medical context is examined in this review. The seven AM process families and various XCT scanning techniques are explained in brief, and the use of these technologies together is detailed over time. The transition of these technologies from a simple method of medical modelling to a robust method of customised implant manufacture is described, and the state-of-the-art for XCT and AM is examined in detail. XCT and AM are identified as having the potential to improve gold standards in both modelling and implant production, and in the conclusions of this review, primary barriers to the increased adoption of AM and XCT technologies are identified in reference to the main applications of XCT and AM technologies. The primary prohibitive factors generally relate to the cost of production across all of the examined applications, as well as the need for further clinical trials in surgical guidance and applications involving implantation.

“…Congenital and, particularly, post-traumatic maxillofacial defects and deformities are notable for a variety of shapes and to replace them not only osteoplastic materials but bone implants (BI) representing the shape of the reconstructed defect are needed [1]. The use of state-ofthe-art software combining the possibility of processing computed tomography data and virtual three-dimensional (3D) modelling enables researchers and clinicians to carry out computer-aided planning in reconstructive surgery and produce models of bone implants completely congruent to the recipient site [2,3], i.e.…”

The aim of the investigation was to develop a technology of manufacturing bone implants based on a hybrid polymer construction composed of poly(3-hydroxybutyrate) and sodium alginate for guided bone regeneration using 3D printing method.Materials and Methods. Complex shaped bone implants based on poly(3-hydroxybutyrate) and sodium alginate were manufactured by the method of two-stage leaching using a mold obtained by 3D printing. The appearance, morphology and structure of the obtained scaffolds were analyzed by means of scanning electron microscopy. Biocompatibility in vivo was determined based on the histology data of scaffolds implantation as bone substitutes.Results. The study of the developed hybrid 3D scaffolds from poly(3-hydroxybutyrate) and sodium alginate showed that they perform a restrictive function providing conditions for regeneration of flat cranial bones in rats.Conclusion. The developed hybrid 3D scaffolds do not interfere with normal osteogenesis and provide beneficial conditions for regeneration.
