METHOD FOR FIXING RADIOPAQUE MARKERS UNDER EDENTIA FOR DESIGNING OF SURGICAL NAVIGATION GUIDE Russian patent published in 2023 - IPC A61C8/00 A61B6/14 

FIELD: medicine; surgical dentistry.

SUBSTANCE: invention relates to medicine, specifically to surgical dentistry and can be used for treatment of patients using dental implants and navigational surgical guide. Method for fixing radiopaque markers when combining computed tomography images in the DICOM file format with intraoral scan of the jaw ridge bone in the STL file format for adentia for designing of surgical navigation guide includes drying oral mucosa, application of Diplen-Dent film on the immobile mucosa of jaw ridge bone, fixing of radiopaque markers from radiopaque liquid-flowing light-cured resin on the film and their polymerisation. Record STL-file by intraoral imaging of jaw ridge bone. Record DICOM file by cone beam computed tomography. They are combined using radiopaque markers, then surgical navigation guide is designed.

EFFECT: improved fixation of radiopaque markers in the oral cavity is approved, thereby minimizing the occurrence of errors when accurately combining computed tomography in the DICOM file format with an intraoral scan of jaw ridge bone in the STL file format under edentia, reducing the risk of radiopaque markers getting into food and the patient's airway.
