For many years, complete dentures have stood as a cornerstone of restorative dentistry, offering a vital solution for individuals dealing with edentulism, ultimately enhancing their oral health and overall quality of life. The traditional approach to crafting complete dentures involves a series of labor-intensive steps, including impressions, and often results in time-consuming processes and potential inaccuracies. Intraoral scanners have recently emerged as a groundbreaking technology within the dental field, revolutionizing the entire process of fabricating complete dentures. In this review, we delve into the current landscape of intraoral scanners for complete dentures. The types of intraoral scanners, along with the technologies used, methods of scanning the edentulous arches, examining the advantages, and addressing associated challenges, are discussed. In the end, we have also shed some light on their future potential to reshape denture treatment.
