Accuracy of a Novel Trace-Registration Method for Dynamic Navigation Surgery
Luigi V. Stefanelli, DDS, PhD/George A. Mandelaris, DDS, MS/Bradley S. DeGroot, DDS, MS/Gianluca Gambarini, MD, DDS/Francesca De Angelis, MD, DDS/Stefano Di Carlo, DDS, PhD

Although the use of dynamic navigation is still novel to dentistry and limited in practice today, its use is widespread in the medical field, addressing specialties, neurosurgery, and/or sinus surgery. “Accuracy of a Novel Trace-Registration Method for Dynamic Navigation Surgery” by Stefanelli et al provides data evaluating the precision of this technology. This retrospective, observational, in vivo study was performed using dynamic navigation via the Trace Registration (TR) protocol. The preoperative cone beam computed tomography (CBCT) plan was superimposed and registered (aligned) with the postoperative CBCT scan to assess accuracy parameters. A total of 136 implants were placed in 59 partially edentulous arches. Mean deviation between the planned and actual position for all implants was 0.67 mm at the coronal level (entry point), 0.9 mm at the apical level, and 0.55 mm in depth, with an angle discrepancy of 2.50 degrees. Tracing 5 to 6 teeth tended to improve accuracy results compared to tracing 3 to 4 teeth. The data support the use of dynamic navigation, and this technology should be further researched and compared with static guides, which are most common today.
