The most common three-dimensional (3D) printing method is material extrusion, where a pre-made filament deposited layer-by-layer. In recent years, low-cost polycaprolactone (PCL) has increasingly been used in 3D printing, exhibiting sufficiently high quality for consideration cranio-maxillofacial reconstructions. To increase osteoconductivity, prefabricated filaments bone repair based on PCL can be supplemented with hydroxyapatite (HA). However, few reports PCL/HA composite extrusion...
Abstract Background Bioresorbable patient-specific additive-manufactured bone grafts, meshes, and plates are emerging as a promising alternative that can overcome the challenges associated with conventional off-the-shelf implants. The fabrication of implants (PSIs) directly at point-of-care (POC), such hospitals, clinics, surgical centers, allows for more flexible, faster, efficient processes, reducing need outsourcing to external manufacturers. We want emphasize potential advantages...
Background/Objective: With the rapid advancement in surgical technologies, new workflows for mandibular reconstruction are constantly being evaluated. Cutting guides extensively employed defining osteotomy planes but prone to errors during fabrication and positioning. A virtually defined plane drilling holes robotic surgery minimize potential sources of error yield highly accurate outcomes. Methods: Ten replicas were evaluated after cutting-guided saw robot-guided laser following with...
Pure orbital blowout fractures occur within the confines of internal wall. Restoration form and volume is paramount to prevent functional esthetic impairment. The anatomical peculiarity orbit has encouraged surgeons develop implants with customized features restore its architecture. This resulted in worldwide clinical demand for patient-specific (PSIs) designed fit precisely patient's unique anatomy. Material extrusion or Fused filament fabrication (FFF) three-dimensional (3D) printing...
Objective To report a digital workflow for use and long-term outcome of cranioplasty with 3D-printed patient-specific Polyetheretherketone (PEEK) implant in 12-y-old German Shepherd dog after surgical removal an extensive occipital bone multilobular osteochondrosarcoma (MLO). Study design Retrospective case report. Animal A 12-year-old neutered female was presented facial deformity, blindness, tetraparesis, ataxia. Magnetic resonance imaging (MRI) computed tomography (CT) identified large...
Cranioplasty with freehand-molded polymethylmethacrylate implants is based on decades of experience and still frequently used in clinical practice. However, data confirming the fracture toughness standard biomechanical tests are rare. This study aimed to determine amount force that could be applied virtually planned, template-molded, patient-specific (n = 10) an implant thickness 3 mm, treatment a temporoparietal skull defect (91.87 cm2), until cracks finally breaks. Furthermore, influence...
To investigate the potential of optical coherence tomography (OCT) to distinguish between normal and pathologic thyroid tissue, 3D OCT images were acquired on ex vivo samples from adult subjects (n=22) diagnosed with a variety pathologies. The follicular structure was analyzed in terms count, size, density sphericity. Results showed that highly agreed corresponding histopatology calculated parameters representative variation. analysis volumes provides quantitative information could make...
Abstract Purpose The use of computer-assisted virtual surgical planning (VSP) for craniosynostosis surgery is gaining increasing implementation in the clinics. However, accurately transferring preoperative data to operating room remains challenging. We introduced and investigated a fully digital workflow perform fronto-orbital advancement (FOA) using 3D-printed patient-specific implants (PSIs) cold-ablation robot-guided laser osteotomy. This novel approach eliminates need traditional...
Abstract The most common surgical procedure to manage the malunion of bones is corrective osteotomy. current gold standard for securing bone segments after osteotomy use titanium plates and allografts which has disadvantages such as possible allergic reaction, additional operations extraction graft from other sites removal operation. utilization resorbable materials presents an opportunity mitigate these drawbacks, but not yet been thoroughly researched in literature. This study assesses...

Abstract Patient-specific osteosynthesis plates can be used to reduce complications related bone fracture treatment, such as infection, malocclusion and fatigue fractures of screws. However, the implant design process is tedious. We propose a semi-automatic workflow computationally patient-specific titanium for mandibular angle fractures. In this process, plate stiffness maximized while mass reduced. Two designs with different numbers screw holes (implant #1 four holes, #2 eight holes) were...

Only a few mandibular bone finite element (FE) models have been validated in literature, making it difficult to assess the credibility of models. In comparative study between FE and biomechanical experiments, we investigate how material properties boundary conditions affect model’s accuracy using design experiments approach.Multiple parameters, such as contact definitions materials' elastic plastic deformation characteristics, were systematically analyzed for an intact model transferred...
