This comprehensive review study examines photogrammetry as a digital imaging technique in modern dentistry. Photogrammetry, using multiple images from various angles, can accurately determine the position of objects in space and create highly accurate three-dimensional models. This technique, initially developed for industrial and mapping applications, is now increasingly used in digital dentistry.
This article reviews the photogrammetry method, the types of devices used (intraoral and extraoral), and its clinical applications in various dental fields, including implantology, orthodontics, and maxillofacial surgery. It also addresses the advantages and limitations of this technique, including accuracy, speed, cost, and ease of use.
The results of this review show that photogrammetry, as an accurate and efficient imaging method, can help improve the quality of digital dental treatments. The high accuracy of photogrammetry enables precise recording of the position of implants, teeth, and facial structures and can contribute to the predictability and accuracy of treatments. The introduction of portable intraoral and extraoral photogrammetry devices has made access to this technology easier in dental offices and has made it possible to benefit from its advantages in everyday clinical conditions.
Overall, photogrammetry is emerging as a powerful tool in digital dentistry and can help improve the accuracy, efficiency, and predictability of dental treatments. However, further research is needed to more accurately investigate the factors affecting the accuracy of photogrammetry and evaluate its clinical applications in real-world conditions.
