Since the eighteenth century, conventional impression techniques have been used to register the three–dimensional geometry of dental tissues. Nevertheless, volumetric changes of impression materials and expansion of dental stone seem error–prone. To overcome these difficulties, impression with IOS (intraoral scanner) was developed for dental practice .The implementation of the IOS device in dental practices coincided with the development of CAD/CAM (computer–aided design and manufacturing) technology in dentistry, with numerous advantages for practitioners. Now–a–days, IOS and CAD/CAM provide easier planning of treatment, case acceptance, communication with laboratories, reduced operative time, storage requirements and reduced treatment times. The fully digitized model–free workflow in a dental practice is possible due to the use of intraoral scanner and the computer–aided design/computer–assisted manufacturing (CAD/CAM) of the restorations. The following case report describes the steps and procedure involved in using IOS for fabrication of an anterior monolithic zirconia crown in a patient
