3D Printing Has Come of Age But How Safe Are the Devices Going Into Our Mouth?

Dr. Frank Alifui-Segbaya

I commenced experimental research into the safety of 3D-printed devices at the time 3D Printing (3DP) was largely considered to be at a “proof of concept stage” in dentistry. I vividly remember how the technology was relatively unknown in my discipline when I arrived on the splendorous Gold Coast, 7 years ago to take up a lecturing position at Griffith University. It is against these backdrops that I would describe the recent hype and the desperate attempt by companies to diversify and innovate competitively as another milestone or perhaps a watershed in the dental specialism concerned with the design and manufacture of devices such as orthodontic splints (Fig.1), surgical guides, and dentures. While it is seemingly laudable that polymers and metals, which form the bulk of dental devices, can now be processed by 3DP, limited scientific evidence exists on their biological safety. It is, therefore, my intention to highlight some pertinent findings from my doctoral study that examined medically-approved photopolymers using the innovative zebrafish embryo model and analytical spectrometry.


3DHEALS Influencer Interview: Stephen Anderson, Renishaw

What do you think is (are) the biggest challenge(s) in 3D Printing/bio-printing? What do you think the potential solution(s) is (are)?

“The biggest challenge(s) in metal 3D Printing for serial end-use production implants are the elimination of machine variability, improving machine productivity and reducing cost per part while maintaining highest provable quality standards in the metallurgy of the part. This will be achieved with continuously improving manufacturing processes and by making deterministic machines so that users can measure machine and process performance. For PSIs the challenges are different: Accuracy of the scanners to capture patient data from which the PSI is modeled. The accuracy of the segmentation software that today still requires humans (source of variation) to make judgments about bone boundaries. Better design osteo-integrable surfaces while considering downstream implant removals. The desirability of on-demand printing and whether every hospital needs a printer etc.”
