Captain Corey Cook, 90th Medical Group dentist, prepares the reinforced porcelain to be cut into a crown that was designed earlier in the appointment at the dental clinic on F.E. Warren Air Force Base, Wyo., Dec. 19, 2017. The milling unit allows for work to be done in house reducing the amount of time it takes to treat a patient, and reducing the amount of lab work needing to be sent to the regional dental lab.
