A REVIEW OF CAD/CAM USE IN DENTISTRY (PART II): COMPARISON OF INTRAORAL DIGITAL SCANNERS USED IN RESTORATIVE DENTISTRY
2014
Introduction: Intraoral imaging technology has become one of the most exciting new fields in
dentistry. Three-dimensional scanning of the oral cavity is used in many dental procedures such as
restorative dentistry and orthodontics. To date, a number of intraoral scanners have been
developed for restorative dentistry throughout the world, and many researchers and manufacturers
seek the design and development of new digital devices. Only some of these devices are currently
available on the market and some others are being clinically tested. All existing intraoral scanners
try to overcome the drawbacks of traditional impression processes. The aim of the present article is
to provide an extensive evaluation of intraoral scanners in restorative dentistry, with special
attention to their assessment principles, characteristics and performance.
Review report: This review article was prepared by scientific searching in electronic sources of
Pubmed and ISI Web of Science in connection with articles published in English until 2014, and
with these key words: intraoral scanners and digital impression.
Conclusion: Over the years there have been major advances in digital scanning systems, and a
variety of digital systems have been introduced that enable the dentist to select different intraoral
reconstruction methods in the extraoral environment. The ultimate goal of dentists is to provide
accurate and efficient dental restorations for the patient, while maintaining patient comfort during
the impression process. High-resolution dental optical scanners will enable the operator to provide
high-quality restorations. With digital impression techniques, the number of operators and material
variables will decrease, making restoration fabrication processes more predictable and easier.
