Cost-effective 3D scanning and printing technologies for outer ear reconstruction: current status

Abstract

Current 3D scanning and printing technologies offer not only state-of-the-art developments in the field of medical imaging and bio-engineering, but also cost and time effective solutions for surgical reconstruction procedures. Besides tissue engineering, where living cells are used, bio-compatible polymers or synthetic resin can be applied. The combination of 3D handheld scanning devices or volumetric imaging, (open-source) image processing packages, and 3D printers form a complete workflow chain that is capable of effective rapid prototyping of outer ear replicas. This paper reviews current possibilities and latest use cases for 3D-scanning, data processing and printing of outer ear replicas with a focus on low-cost solutions for rehabilitation engineering.

Lower Jaw Full-Arch Restoration: A Completely Digital Approach to Immediate Load

“…The ability to precisely select and tailor materials is essential to provide the best possible results and a favorable prognosis in longterm follow-up [28][29][30][31][32]. In addition to the clinical benefits, the efficiency of laser sintering and laser melting in the production of prosthetic elements promises to reduce time and costs [33,34]. This is a win-win situation, as it improves the convenience and accessibility of these advanced techniques for practitioners and translates into more convenient solutions for patients [35].…”
