Abstract

 Today, intraoral mapping technology is one of the most exciting new areas in dentistry since three-dimensional scanning of the mouth is 
required in a large number of procedures. since the concept of intraoral digital impression was put forward in early 1980s. This new digital 
impression technique is expected to bring about absolute digitization to the mode of Prosthodontist. An optical-impression by an intra-oral 
scanner (IOS) involves optically measuring the surface shape of the target teeth or gums directly in the patients mouth. These systems are 
capable of capturing 3D virtual images of tooth which can be used to create accurate master model on which the restorations can be made in 
a dental laboratory. Precision, accuracy, and hassle-free procedures have made these systems user-friendly and patient – friendly. The use of 
these products is rapidly increasing around the world and presents a paradigm shift in the way in which dental impressions are made. These 
article discuss: (1) How IOS works; (2) categories and principles of IOSs; (3) different types of IOSs currently available; (4) accuracy of intra 
oral scanners; (5) advantages and limitation of IOSs; (6) accuracy of IOSs; and (7) clinical impact of IOSs
