From traditional dental impressions to the contemporary era of digital precision, the evolution of intraoral scanning reflects a paradigm shift in dental diagnostics and treatment planning. In recent years, there's been a remarkable surge in the variety of optical intraoral scanners dentists can choose from. The market has expanded significantly, giving dental professionals more options than ever before when selecting this essential technology for their practices.The intraoral scanners that are present: the TRIOS Classic, the TRIOS 3Mono Intraoral Scanner, the LAVA C.O.S., the CEREC Omnicam, the iOC intraoral scanner, the CS3600 Carestream, the iTero Element intraoral scan and the Lythos. With exciting innovations and broader applications in orthodontics, intraoral scanning systems are revolutionizing dentistry. These clever devices capture 3D digital impressions by projecting light onto teeth and implants, promising a bright future for dental care.We explore the technological milestones that paved the way for today's sophisticated scanners, examining their pivotal role in enhancing accuracy, efficiency, and patient experience. This abstract delves into the transformative journey of intraoral scanners, spanning their historical roots, current applications, and the exciting prospects shaping their future. Looking ahead, we anticipate the integration of artificial intelligence, improved ergonomics, and broader applications, heralding a promising future where intraoral scanners continue to redefine oral healthcare standards.
