Development and evaluation of navigation system for dental implant surgery completed in all-in-one visit Sung-Goo Kim, DDS, MSD Department of Oral and Maxillofacial Radiology The Graduate School Seoul National University Purpose: In this study, we have developed a new image guided navigation system for dental implant using cone-beam computed tomography image, and evaluated its accuracy. Materials and methods: Image guided navigation system based on an optical tracking camera was developed. In the developed system, new instrument tracking tool and patient tracking tool were applied. A patient-specific splint was improvised using a bite splint and dental impression material. Also, registration method using pre-recorded fiducials and direct offset determination method were developed. Accuracy of these registration and direct offset determination methods was measured through target registration errors (TRE) of 10 ceramic spheres. To measure error of the image guided navigation system for placed implants, the 110 implants were actually installed, and the accuracy of the developed system was evaluated. Results: The total mean (± SD) TRE of newly developed system was 0.35 ± 0.11 mm. After registration by pre-recorded fiducials, the mean TRE was 0.34 ± 0.18 mm. The offset for a random drill was directly calibrated, and then by using it, a mean TRE was 0.35 ± 0.16 mm as a result. There was no significant difference (P > 0.05) in accuracy among registration methods and direct offset determination. The total mean error between 110 planned implants and the actually placed implants was 0.41 ± 0.12 mm at the center point of platform, 0.56 ± 0.14 mm at the center point of apex, and 2.64 ± 1.31 ° was the angular deviation of the long axis of the implant. Conclusion: A new image guided navigation system based on CBCT images for dental implant was developed to overcome some disadvantages of the conventional method, and the accuracy of the developed system was proved to be sufficiently high for clinical application. It will be possible to perform a dental implant surgery in all-in-one visit by using the developed image guided navigation system. Keywords: Image-Guided Surgery | - |
