Dynamic navigation systems (DNS) provide real-time visualization and guidance to the operator during endodontic access cavities preparation. The planning of the procedure requires three-dimensional imaging utilizing cone beam computed tomography and surface scans. After the export of the planning data to the DNS, access cavities can be prepared with minimal invasion.

FAQs
The system combines imaging data with sensor-based tracking to establish a three-dimensional reference for the bone and the planned correction. During surgery, the surgeon can compare the bone’s actual position with that reference in real time. This supports control of the osteotomy location, cutting angle, correction magnitude, and fixation or implant placement.
Real-time comparison helps the surgeon assess whether the bone position and the developing correction correspond to the preoperative plan. That feedback can make the procedure more reproducible and may reduce reliance on limited visual or fluoroscopic information. It also supports controlled correction while helping preserve healthy bone and surrounding soft tissue when appropriate.
The technique can support precise control over several linked variables: where the osteotomy is made, the angle of the cut, the magnitude of the planned correction, and the position of implants or fixation. Controlling these elements within one navigated reference system helps connect the bone cut with the intended skeletal alignment rather than treating each step independently.
Visual or fluoroscopic guidance may provide less complete information when the desired correction depends on three-dimensional relationships. Navigation adds an image-based, sensor-tracked reference that allows ongoing comparison with the plan. Its value is greatest when conventional guidance is limited, because the surgeon can monitor alignment-related variables instead of depending solely on direct visualization or intermittent imaging.
The workflow begins with imaging and patient-specific planning before surgery. During the operation, navigation sensors establish the relevant three-dimensional reference system, and the surgeon uses it to guide the planned bone cut. The correction is then assessed against the reference, while fixation or implant placement can also be supported by the same navigational information.
This approach may be considered when surgery aims to correct a skeletal deformity, restore alignment, or support reconstructive treatment and conventional visual or fluoroscopic guidance is insufficient. Its patient-specific planning and intraoperative feedback can be especially relevant when the location, angle, or size of the correction must be matched closely to an individualized skeletal plan.
Navigation can provide information about whether the osteotomy is being performed at the planned location and angle, whether the correction approaches the intended magnitude, and whether fixation or implant placement corresponds to the plan. These data support intraoperative decision-making and help document how the completed reconstruction relates to the patient-specific alignment objective.
