From Precision to Intelligence: The Evolution of Intraoral Scanning

Intraoral scanning has evolved from a promising alternative to conventional impressions to a mainstream data-acquisition tool across nearly every dental field. As adoption has matured, however, the clinically relevant issue has shifted: it is no longer whether intraoral scanners (IOSs) are accurate enough, but rather under which conditions their accuracy holds and how artificial intelligence (AI) is now being integrated into the scanning process itself to close the remaining gaps. This article revisits the evidence on IOS accuracy and assesses the emerging role of AI-driven software and supporting hardware in improving scan reliability, particularly in demanding clinical scenarios such as complete arch and implants.
