Tammy Pilcher, with the 78th Operation Readiness Medical Squadron Dental Flight, demonstrates the use of Reprosil, a material used to make dental impressions, at the dental clinic at Robins Air Force Base, Georgia, March 11, 2020. Expired Reprosil is given to the Warner Robins Air Logistics Complex where it is repurposed by engineers to create three dimensional molds of parts that are either missing or in hard to reach areas where conventional measuring devices are not able to be used, saving the Air Force $2.5 million annually.
