Intraoral scanners (IOS) are reshaping modern dentistry by offering a digital alternative to traditional impression techniques. This review aims to analyze the accuracy, reproducibility, and patient satisfaction associated with IOS compared to conventional methods. A comprehensive review of academic. Studies were assessed for methodological strength, participant characteristics, and outcomes concerning accuracy, reproducibility, and patient satisfaction. Results suggest that IOS generally performs as well or better than traditional impression methods, especially in terms of precision and reproducibility, while also delivering high levels of patient satisfaction due to improved comfort. Challenges remain, such as the cost of the technology, the learning curve for practitioners, and some technical limitations. The findings suggest that standardizing methodologies and assessing long-term performance could aid in overcoming these barriers. This review also highlights the need for increased adoption through improved training and cost management.This review aims to provide a detailed evaluation of the accuracy, reproducibility, and patient satisfaction associated with intraoral scanners compared to traditional impression techniques in dentistry.
