From Academia: 3D-Printed Aligner, Bioprinting for Mouth Ulcer, Vertebroplasty Guides

This week’s collection comes from many different fields, including digital dentistry, spinal surgery, orthopedics, pharmacology, and more. The conclusion drawn from comparing the geometric and mechanical properties of the conventional thermoformed versus 3D-printed aligner showed a clear advantage of the 3d-printed version. However, scalability will remain a question. That said, this makes it easier to deliver dental aligners to patients who have little access to large scale commercial dental aligner products, removing third party involvement from the dentist and the patient, and possibly delivering higher quality and quick service. In the medical 3D printing section, one group provided a thorough review of how they use a 3D-printed guide to help with vertebroplasty procedures in osteoporotic patients who experienced vertebral body compression fractures. Having participated in several such procedures myself, it is definitely a relief that surgeons/interventionist is looking into ways to remove the “art” part of practicing medicine and aim for more precision. In pharmacology, more studies are showing up focusing on the on-demand formulation of medications for a variety of needs using 3D printing. In the world of design, researchers are trying to design the best device to reduce the impact of falls, using 3D printing. This is especially important in elderlies, who often experience life-threatening injuries. This brings back the subject of generative design, where computers inspire the designers and equip them with performance data.
