Objective. To evaluate the morphometric features of the topical and morphological location of permanent third molars and the possibility of personalized prediction of their eruption, to determine indications for removal using precision data from extended cone-beam computed tomography. Methodology. 134 patients aged 17–35 years diagnosed with distal occlusion underwent extended cone beam computed tomography. In the program interface, the features of the location of permanent third molars were visualized using panoramic reformats and modernized methods were used to predict their eruption by constructing internal angles. Based on the results of the analysis, recommendations were made for the removal of individual teeth. Results. On panoramic CBCT \-scans of the upper jaw we visualized 162 1.8 and 2.8 teeth (100%), of which 45 were in retention (27.78 ± 3.52%) and 117 were impacted (72.22 ± 3.52%). Normal parameters of internal angles greater than 90° were determined for 135 1.8 and 2.8 teeth (83.33 ± 2.93%). Abnormal parameters of internal angles less than 90° were determined for 27 1.8 and 2.8 teeth (16.67 ± 2.93%). Diagnostic CBCT-scans of the lower jaw visualized 211 3.8 and 4.8 teeth (100%), of which 77 were in retention (36.49 ± 3.31%) and 134 were impacted (63.51 ± 3.31%). Normal parameters of internal angles greater than 70° were determined for 31 3.8 and 4.8 teeth (14.69 ± 2.44%). Abnormal parameters of internal angles less than 70° were determined for 180 3.8 and 4.8 teeth (85.31 ± 2.44%). To prevent the development of pathology, all teeth with abnormal parameters of internal eruption angles were removed. Conclusion. Extended CBCT allowed us to visualize retended and impacted permanent third molars on both jaws, analyze the features of their topical and morphological location and determine indications for the individual teeth removal.
