Abstract

Background:  Increased use of emerging technology in prosthodontics has resulted from rapid and persistent developments in computer sciences. One of them is an intra-oral scanner. Intraoral scanners (IOS) are devices used in dentistry to acquire direct optical impressions. Optical impressions reduce patient discomfort, and they are particularly useful in conditions where conventional impression techniques are contraindicated. A paradigm shift in prosthodontics reflects the replacement of alginate and polyvinyl siloxane (PVS) impressions with optical intraoral scanners. In dental practises, the implementation of the IOS device coincided with the advancement of CAD / CAM (computer-aided design and production) technology for best performance. The current IOS can be used with good accuracy to capture impressions for variety of prosthodontic procedures. As the use of scanners is increasingly adopted by dental practises, it can be fair to assume this degree of accuracy in impression taking and scanning. This review will give more light on the use of IOS in prosthodontics.
