Digital dentistry refers to diagnosis, design, treatment and information tracing by computer technology and aided equipment, among which CAD/CAM technology, the computer aided design and computer aided machining, is a kind of digital dentistry technology that are widely applied to dental restoration.

Today, dental laboratory could produce dental crown, dental bridge, plaster model and planting guide template exactly, quickly and high efficiently by 3D scanning, CAD/CAM design and 3D printing. Design and manufacturing of dental restorations are mainly made manually in clinic and efficiency is low, however, digital dentistry showed broad space for development. Digitized technology could release the heavy manual work and eliminate the bottleneck of precision and efficiency caused by manual modelling.
