U.S. Air Force Maj. Samuel Durham, 8th Medical Operations Squadron Dental Flight commander, holds a crown made by a Chairside Economical Restoration of Esthetic Ceramics machine at the dental building on Kunsan Air Base, Jan. 20, 2019. The CEREC machine will allow the dental flight to make crowns and caps same day, instead of having to send stone castings to another clinic. (U.S. Air Force photo by Staff Sgt. Joshua Edwards)
