Clinical application and new progress of dynamic navigation system in the field of oral implantology / 口腔疾病防治

ABSTRACT

@#Currently, computer-aided implant surgeries include implant placement surgery under the guidance of a dynamic navigation system. With the use of software inherent in the navigation system, doctors can make a preoperative plan including the ideal position of the implant. Then the plan can be accurately transferred to the surgery, during which the real-time condition of the drill and its relationship with the surgical region will be visualized by the surgeon and the drill can be adjusted in a timely manner. Currently the dynamic navigation system is increasingly widely utilized, especially in cases of esthetic zones or surgical sites with important anatomical structures. However, the clinical workflow of the navigation system is complicated, including CBCT taken after the registration device placement, prosthetic-driven 3D design, calibration, registration, navigated borehole preparation and implant placement surgery. Many details should be considered when the device is applied, including implant position design, fixation of the tracking device, registration, and stable borehole preparation under the guidance of dynamic navigation. Therefore, this article introduces the dynamic navigation system into the clinical workflow and evaluates, the effects of the application and the clinical features. The new progress of the navigation system in the field of implantology is demonstrated at the same time, including navigated surgery in fully edentulous arches and in the zygomatic zone. Further improvements in the navigation system in terms of the accuracy and simplification of the workflow are needed in the future.
