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.

I. Introduction

With the continuous advancement of computer vision and image processing technologies, minimally invasive surgical techniques guided by visual imaging have met the demands for reduced trauma and precise positioning [1]. Particularly in dental implant surgeries, high precision in positioning is crucial to ensure the accurate placement of implants and the maintenance of oral health. Traditional freehand implantation methods are limited by the surgeon's experience and the local field of view, presenting challenges in surgery.
