“…While the US has performed similar trials nationwide, China has become a world leader in innovative and complex bone replacement surgeries as illustrated for example in Figure 5 (Cai, 2015;Xia et al, 2019). China has also embarked on programmes to manufacture SLM and EBM systems and Gadia et al, 2018;Huang et al, 2019;Kalaskun, 2017;Lee et al, 2020;Murr, 2019Murr, , 2020Tofail et al, 2018;Wohlers Report, 2019, 2019Woo et al, 2020;Zhang & Chen, 2019). This trend in global customizing of biomedical devices might be popularly referred to as mass-personalization which is made possible by 3D printing in point-of-care surgical service centres, along with other emerging technologies (Marr, 2020).…”

“…While COVID‐19 has variously dominated hospital functionalities worldwide in the first half of 2020, the passing of this global pandemic will likely see a rapid return to the proliferation of patient‐specific, complex, open‐cellular biomedical implant device development, clinical trials and the establishment of bone‐related surgical service centres producing a wide range of custom bone replacement devices; based in part on contemporary applications and market analyses (Ahangar et al, 2019; Dall’Ava L et al, 2019; Gadia et al, 2018; Huang et al, 2019; Kalaskun, 2017; Lee et al, 2020; Murr, 2019, 2020; Tofail et al, 2018; Wohlers Report, 2019, 2019; Woo et al, 2020; Zhang & Chen, 2019).

The use of stones, shells, wood, bone, ivory and iron and copper for surgical implants (especially teeth) dates back more than 4000 years (Hildebrand, 2013; Howland, 2018). The use of metal and alloy surgical implants for various bone repair and replacement was introduced around the end of the 19th century following the development of x-radiology and the discovery of anaesthetics and antiseptics to reduce infection. Stainless steel plates and screws to repair bone fractures were among the first biocompatible materials (circa 1926) followed by titanium and cobalt-based alloys introduced

“…Recently, computer-aided design (CAD) and computer-aided manufacturing (CAM) have been successfully used in maxillo-facial traumatology and reconstructive surgery [ 18 ]. CAD/CAM technology provides opportunities for surgeons to: simulate the operation on a computer, perform virtual fragment repositioning, select the appropriate method of fixation, and increase the precision of surgical manipulations by manufacturing surgical guides or patient-specific implants.…”

Biomechanical evaluation of type p condylar head osteosynthesis using conventional small-fragment screws reinforced by a patient specific two-component plate

et al. 2020

Background The aim of this study was to evaluate via finite element analysis (FEA) the biomechanical behavior of conventional small-fragment screws reinforced by a patient-specific plate in type p condylar head. Methods A finite element model of the mandible was created using Mimics 12.1 software. A type p condylar head fracture was simulated in the right condyle, and the left condyle was used as a control. Two patterns of fixation were investigated: conventional two-screw fixation and the same fixation system reinforced with a small, patient-specific plate. Surface models were imported into the software Ansys 5.7for further volume mesh generation. Results The highest stress gradients were observed in the cortical layer of the lateral fragment, located near the screw. The conventional fixation method resulted in equivalent stresses 2 to 10 times greater than the reinforced method. Rigidity of fixation in the reinforced method increased up to 1.25–3 times compared to the conventional two-screw technique. Conclusion This study’s findings suggest significant benefits in unfavorable biomechanical conditions from reinforcement of the standard two-screw fixation of condylar head fractures with a small, patient-specific plate acting as a washer.

Surgical guides for proper repositioning and xation as well as patient-speci c plates have been successfully used by Suojanen J, Chepurnyi, and Yang in orthognathic surgery and orbital, midfacial and mandibular reconstruction.…”
