Digital implant planning, utilizing the convergence of digital surface scanners, cone beam computer
tomography (CBCT) scans, and advanced planning software, has transformed dental implantology. The
merging of these data sets through triangulation of landmarks provides a detailed digital model of the
jaws, facilitating precise implant positioning in edentulous areas. A critical step in this digital workflow
is the accurate merging of DICOM files with STL/PLY/OBJ files, which underpins the design and
fabrication of surgical templates for accurate implant placement. Errors in this phase can lead to
implant mispositioning or damage to adjacent structures. Particularly in partial edentulism, the merging
is based on the occlusal topography of the remaining teeth but scattering in the CBCT data—caused by
interactions of radiation with radiodense materials—can complicate this process or even render it
impossible. The manuscript presents a technique utilizing radiopaque markers to overcome scattering
effects, ensuring accurate dataset superimposition in the mandible.
