Intraoral scanners (IOS) are devices used for making optical or digital impressions in dentistry. These scanners can be used in various fields of dentistry such as Prosthodontics, Orthodontics, Implant surgery, endodontic dentistry etc. They have the advantages of reducing operative time for clinicians, enhancement of clinician patient communication and simpler clinical procedures. Recently, these advanced technologies are used more often than conventional techniques to overcome the hitches associated with conventional techniques. This article highlights the pros and cons of intraoral scanners with two case reports.
