High-precision all-in-one dual robotic arm strategy in oral implant surgery

INTRODUCTION: Dental implantation has emerged as an efficient substitute for missing teeth, essential for restoring oral function and aesthetics. Accurate positioning, angulation, and depth are critical to long-term success and require high-precision operation and technical support. METHOD: We propose an integrated dual-arm high-precision oral implant surgery navigation and positioning system and a corresponding control strategy. The all-in-one dual-arm design shortens preoperative preparation and simplifies operation. A novel control flow includes an Occluded Target Tracking Module (OTTM) for occlusion-robust tracking, a Planting Plan Development Module (PPDM) for generating implant plans, and a Path Formulation Module (PFM) for coordinating the motion paths of the two robot arms. RESULT: In clinical trials, the system achieved high accuracy: for five patients, the average angular error and entry point error were 2.1° and 0.39 mm, respectively. CONCLUSION: The integrated dual-arm system resolves long preoperative calibration and static planning limitations. Clinical results confirm efficacy, highlighting accuracy and precision in guiding oral implant procedures.
