Digital Impressions in Prosthodontics: Contemporary Concepts, Technologies, and Clinical Methodologies: A Narrative Review

Abstract

Digital impression technology has revolutionized prosthodontic practice by providing a reliable and efficient alternative to conventional impression techniques. Through accurate three-dimensional recording of intraoral structures, digital impressions have facilitated seamless integration with computer-aided design and computer-aided manufacturing (CAD/CAM) systems, thereby enhancing diagnostic accuracy, treatment planning, and prosthesis fabrication. This narrative review explores the fundamental concepts, technological principles, clinical workflows, scanner systems, accuracy, advantages, limitations, and future prospects of digital impression techniques in prosthodontics, with an emphasis on their expanding clinical relevance.
