Research on Passive Optical Dental Implant Dynamic Navigation System Based on Binocular

In the digital era, the continuous advancement of computer technology has profoundly impacted the field of clinical medicine. Surgical navigation, as a key application of computer-assisted navigation, has played a pivotal role in surgical procedures. The integration of medical imaging and positioning technologies has driven surgery towards minimally invasive approaches and higher precision, offering safer and more effective treatment options for patients. Particularly in the field of dental implantology, precise surgical positioning and real-time monitoring are paramount. This paper introduces a dynamic navigation system for dental implants that utilizes passive optical positioning. The system relies on tracking the reflection of markers through dual-camera optical sources, establishing spatial relationships among the patient's oral cavity, the dual cameras, and the dental implant instrument. This technology not only enables precise registration of image data with the position of the drilling needle but also calculates and determines the spatial coordinates of the dental implant's tip in real time. These critical pieces of information are intuitively presented on a visual screen, integrating with the preoperative virtual model of the implant site. This allows surgeons to continuously monitor the angle and depth of implant placement in real-time, facilitating necessary adjustments during the surgical procedure. Consequently, this approach enhances the precision and safety of dental implant surgeries.
