Accurate dental implant fixture placement is critical for optimal restorative functional and esthetic outcomes. Computer-assisted implant surgery, including static computer-assisted implant surgery and dynamic computer-assisted implant surgery systems, improves accuracy compared to freehand techniques. Augmented reality (AR) offers further benefits by integrating preoperative planning with real-time intraoperative visualization, enhancing surgical results and providing valuable tools for training future implantologists. However, high costs and technological complexity have limited its widespread adoption. This technical note presents the first clinical application of a mobile-visualized AR navigation system. While the intraoperative interface operates on a smartphone, the system is built upon a comprehensive digital workflow involving cone-beam computed tomography imaging, intraoral scanning, photographic data, and bite registration for dynamic implant navigation in the anterior maxilla. Postoperative analysis showed maximum deviations of 2.0 mm in implant apex position and 9.15° in angulation from the planned trajectory. These results confirm accurate implant placement and support the feasibility of smartphone-based AR as a cost-effective, accessible solution for digital navigation in implantology. Further research with larger sample sizes is warranted to validate these preliminary findings.
