Bellus3D Company proposed to apply their face scan software, used with selected smartphones and tablets, to design and 3D-print a bespoke “Mask Fitter” to improve the sealing of surgical masks and respirators. They should adapt to the persons facial anatomy, but this is not always easy to achieve. The tested Mask Fitter device could represent an easy and low-cost procedure to improve the facial adaptation of the FFP2 respirator.Ībstract = 'COVID-19 has deeply impacted clinical strategies in dentistry and the use of surgical masks and respirators has become critical. Moreover, fogging problems decreased considerably.

Dental staff gave positive feedback, with levels of comfort during daily use reported as similar with and without the Mask Fitter and a higher confidence in achieving a proper seal, ranging from a 10% confidence rating of a proper seal without the Mask Fitter to 75% with the Mask Fitter. Questions were asked about wearing comfort, sealing confidence, glasses or loupes fogging, both with and without the Mask Fitter. Participants were asked to wear their Mask Fitter over one week and then completed a survey. Twenty dental staff participants were face scanned and a Mask Fitter for FFP2 respirators was designed and 3D-printed. They should adapt to the person’s facial anatomy, but this is not always easy to achieve.
