According to the development of digital dentistry, clinical and laboratory procedures to fabricate prostheses becomes more easier and simple. Recently, dental computer aided design/ computer aided manufacture (CAD/CAM) system is widely used to make fixed restorations, removable restorations and implant prostheses. For the use of computer aided design software, model scanner was used to scan the model which is taken with conventional impression methods. Also, nowadays, intraoral scanners are introduced and used to take scan date directly from the patient mouth. Digital impression using Model scanner and Intraoral scanner has advantages such as reduce the chair time and laboratory time, reduce the patient’s discomfort or pain by cord packing, restore the data without distortion, reduce the dental visit etc. In this study, we reported principles of Model scanner and Intraoral scanner, and clinical application of digital impression.
