Intraoral and extraoral scanners have revolutionized dental practice by providing high-precision digital impressions, transforming how dental procedures are performed. Scanners create detailed digital models of a patient's dental anatomy, allowing for more precise diagnostics and treatment planning. Precision and accuracy are crucial in dental scanning, as they directly impact the quality and dependability of digital impressions. Accuracy encompasses two key concepts: precision and trueness. Precision refers to the consistency and repeatability of measurements, ensuring that the digital model maintains loyalty to the original scan. Trueness relates to the degree of agreement between the digital scan and the actual anatomical structure, ensuring accurate representation without distortion. Intraoral scanners offer real-time data capture directly from the patient’s mouth. Digital impressions created with intraoral scanners reduce the need for traditional impression materials, lowering the risk of mistakes associated with analog impressions. Extraoral scanners handle larger and more complex models with high precision, ensuring efficient workflows and accurate restorations. New scanners on the market are introducing modern software and artificial intelligence, dramatically increasing the quality and usability of these scanners, reducing mistakes, and improving the scanning process. The choice between intraoral and extraoral scanners depends on specific accuracy, precision, and workflow requirements. Intraoral scanners are ideal for immediate, chairside use, while extraoral scanners excel in laboratory environments where large-scale, detailed models are necessary. Both types of scanners are crucial in advancing digital dentistry, ensuring high-quality outcomes, and enhancing the overall patient experience.
