From: Guided endodontic treatment in a region of limited mouth opening: a case report of mandibular molar mesial root canals with dystrophic calcification

Fig. 3

The DICOM data is segmented in an STL file for the 3D reconstruction of the mandible; the mandibular first molar with dystrophic calcification is in yellow (a). The CBCT image shows a buccolingual view of the obliterated mesial root with the virtual drills and respective virtual sleeves positioned in the access pathway (b). MB is the mesiobuccal, and ML is the mesiolingual root canal, respectively. The image also shows an estimated length of the obliterations from the flor of the pulp chamber to the remaining lumens (b). The axial view shows the virtual sleeve and drill for the fixation pin (c)
