Capt. (Dr.) Derek Sloan, 2nd Dental Squadron general dentist, takes an optical impression during an exam at Barksdale Air Force Base, La., Feb. 12, 2016. Optical impressions replaced the old wet impression process, decreasing the time needed to create a physical cast. The new process reduced completion of crowns from two weeks to approximately two hours. ( Air Force photo/Airman 1st Class Mozer O. Da Cunha)
