BACKGROUND: Dental implant placement navigation systems based on optical tracking have been widely used in clinics. However, electromagnetic (EM) navigation method that does not suffer from problems of hidden line-of-light has not yet been described. METHODS: This work proposes an EM-guided navigation method named TianShu-ESNS with virtual calibration. Model (12 implants) and animal experiments (pig head: six implants) were conducted to evaluate its performance and stability. RESULT: The mean virtual calibration error was 0.83 +/- 0.20 mm. The mean deviations at the entry point, end point and angle in the phantom experiment of TianShu-ESNS were 1.23 +/- 0.17 mm, 1.59 +/- 0.20 mm and 1.83 +/- 0.27 degrees , respectively. In the animal experiment, the same deviations were 1.25 +/- 0.07 mm, 1.57 +/- 0.35 mm and 1.90 +/- 0.60 degrees , respectively. CONCLUSIONS: The experimental results show that TianShu-ESNS with the virtual calibration method could serve as a promising tool to eliminate the line-of-light hidden problem and simplify operation procedure in dental implant placement.
