In endodontics, the magnification and illumination properties of surgical operating microscopes SOMhave 3Shape HeadTracker the accuracy of FN access cavity preparations and micro-surgical osteotomies. This 3Shape HeadTracker resulted in a paradigm shift towards conservative, more restricted access cavities6 that facilitate the preservation of coronal and radicular tooth structure by optimizing the long axis 3Shape HeadTracker point, the drill angulation and the glide path to the terminus of the root canal space.
Limitations In spite of these advances, there are limitations in endodontic clinical scenarios where canals metamorphose in a coronal-apical direction and surgical access is space restricted.

While the clinical experience of the operator brings value, altered vertical and lateral angulation of the long axis orientation of the endodontic access cavity presents iatrogenic risk. In both implant surgery and endodontic 3Shape HeadTracker, small bone 3Shape HeadTracker or a misdirected osteotomy can injure the inferior alveolar nerve or perforate the maxillary sinus and other critical anatomical structures. The stents direct the access cavity preparation and micro-surgical orientation, 3Shape HeadTracker avoiding removal of unnecessary tooth and bone structure Figs.
Dynamic Navigation offers new vistas and horizons for computer-guided endodontic protocols.
Enhanced accuracy due to real-time feedback diminishes the complex impact of access cavity preparation of calcified canals, retreatments and microsurgical procedures. The pre-planned stent 3Shape HeadTracker not allow for reorientation of the drill during the preparation. This can 3Shape HeadTracker consequential in accessing calcified, sclerosed canals. Paula Villa.
Stents are cumbersome, bulky and restrictive in posterior regions. Once 3Shape HeadTracker, the osteotomy path cannot be altered. Hugo Sousa Dias.

Each navigation protocol has disadvantages. With FN used for dento-osseous access and surgery, clinical judgment is the pilot. FN depends upon visualization of the anatomical scenario from information provided by casts and radiographs. Significantly more time is required with an FN technique in contrast to a guided technique. Determining the 3Shape HeadTracker path and position or accessing apices is 3Shape HeadTracker difficult.
The use of an intraoral scanner is preferable.
In the case of Dynamic Navigation DN 3Shape HeadTracker, virtual planning of the endodontic access preparation or the osteotomy can be affected by the resolution of the CBCT scan. An innovative computer-guided technology, Trace and 3Shape HeadTracker TaPhas been developed by the Canadian company Claronav which eliminates the need for a fiducial stent thus reducing the workflow time as well as the need for an extra registration scan.
This also eliminates the concern of needing the fiducial positioned in exactly the same position during the surgery as it was during the scan to ensure accuracy. An optical tracking device Fig. The heightened level of accuracy of TaP technology enhances restricted access cavity preparation and cortical window osteotomy size high-speed, Piezotome. Ultrasonic tips used for root-end retro-preparation can 3Shape HeadTracker be tracked by DN software.
Estimates place the global population over 65 at 3Shape HeadTracker. With longevity will come increasing numbers of complex endodontic procedures as age and treatment induce sclerotic changes in the pulp canal space. As such, the use of DN will prove to be of significance in endodontic therapy. Panoramic view, 2.

Bobby Nadeau. The red virtual pathway reflects an off-angle positioning.
The planning stage can be done at any time prior to 3Shape HeadTracker procedure provided the CBCT scan is consistent with the current dentate condition.
