Dynamic navigation refers to the use of a surgical navigation system for implant placement, which can design the location of a virtual implant according to the CT data. In addition, the system allows real-time tracking of the implant drills and the patient throughout the operation based on motion tracking technology. The designed implant location and the size, length, width, and shape of the implant can be changed during the operation when it is needed to be changed according to the actual intraoral condition of the patients.
