DOVER AIR FORCE BASE, Del. – Tech. Sgt. Raymond Worl, 436th Dental Squadron NCO in-charge of the dental laboratory, uses a three-dimensional digital computerized milling unit incorporating Computer-Aided Design technology to fabricate all-porcelain crowns for difficult dental cases. Sergeant Worl uses the computer to scan the patient's tooth preparation area. This scan produces a 3-D replica of the patient's mouth displayed on the computer and is used to mill the all-porcelain crown. The lab tech is able to make adjustments such as size, contour, and anatomy before actually milling. (U.S. Air Force photo/ Airman 1st Class Shen-Chia Chu)
