3D Printed Scaffolds Evaluated for Mandibular Reconstruction http://bit.ly/2KbRFIl In ‘Digital Design, Analysis and 3D Printing of Prosthesis Scaffolds for Mandibular Reconstruction,’ we learn more about strides in the medical field regarding mandibular surgeries, reconstruction, the potential for current and future improvements in implants, as well as understanding more about the obstacles today and how they can be overcome. 3D printing is invaluable to the medical field overall due to the ability to customize nearly everything—and offer patient-specific care to individuals who may have faltered under previous one-size-fits-all restrictions. Customized implants especially are offering new options to patients, as porous, lightweight structures can be created to aid in reconstruction and the eventual return to normal functions such as chewing and swallowing nutrients. For this study, Saudi researchers from King Saud University created two different customized scaffold designs (a top and bottom plate, and an inner porous plate) which they later evaluated regarding both usefulness and aesthetic appearance. The authors describe the perfect scaffold as one that is highly porous, without cracks, and fully biocompatible. Previous studies have shown that titanium is highly effective as a material but may also lead to deterioration of mechanical properties and eventual resorption or failure of the implant. 3D printing has offered potential in reconstruction, but also rehabilitation, and surgery too.
Until now, the researchers state that there has been no clear research regarding mandibular reconstruction or biomechanical properties, stability and integrity, or testing of related scaffolds and structures. Here, they studied a patient, at 40 years old, suffering from deformities and a ‘lesion in the left mandibular area.’ The patient was treated in an emergency department initially, beginning with a series of CT scans uncovering a mandibular continuity defect, and substantial loss of bone. The images were converted into 3D files using Materialise Mimics software, and then an FDM 3D printer was used with ABS material to create the framework model. A Formlabs 2 SLA 3D printer was then used for fabrication of the mandibular prosthesis scaffold. The researchers evaluated the structures for weight, integrity, and accuracy, using a micro-CT scan.
Mandibular reconstruction can be a challenging endeavor, but when successful it offers incredible value to patients who may be having trouble chewing, as well as enduring understandable self-consciousness due to a defect or tumor removal. This is big topic of research and has also led to numerous innovations via 3D printing, from alveolar ridge augmentation to mandibular grafts, and implants for cancer patients.
