Additive and Subtractive Manufacturing in Prosthodontics

Digital technology such as computer-aided design and computer-aided manufacture (CAD/CAM) is rapidly expanding and transforming dentistry at an unprecedented pace. CAD/CAM technology in dentistry can be classified as either "subtractive" or "Additive" manufacturing methods. Subtractive manufacturing methods include machining and milling (CAM) and laser ablation technologies, while additive manufacturing methods includes 3D printing and laser melting technologies.
