Photogrammetry is a digital imaging technique that uses multiple photographs taken from different angles to accurately determine spatial relationships and produce three-dimensional models. Originally developed for industrial and cartographic purposes, photogrammetry has recently gained attention in dentistry due to its potential for enhancing precision in digital workflows. This review introduces the fundamental principles of photogrammetry and examines its use with both intraoral and extraoral devices. Clinical applications across implantology, orthodontics, and maxillofacial surgery are discussed, highlighting the method’s advantages in capturing the spatial position of dental and facial structures with high accuracy and efficiency. Despite its benefits, photogrammetry also presents limitations, including sensitivity to technical and environmental variables, as well as a need for further validation through real-world clinical studies. The advent of portable and user-friendly systems has expanded access to this technology in dental practice, indicating that photogrammetry may play a significant role in improving the accuracy and quality of digital treatment planning and execution.
