ABSTRACT
Objective: To determine the anatomical variants produced between the mandibular canal and the superior, inferior, external and internal alveolar cortices in edentulous patients with respect to dentate patients posteroinferior in computed tomography (CBCT).
Methods: Fifteen tomographies were studied in edentulous patients and 15 in dentate patients in the posteroinferior sector, of both sexes in patients with an age range between 50 and 65 years. They were measured in oblique cuts from the mental foramen making 5 posterior cuts every 4 millimeters. In each cut, measurements were made from the mandibular canal to the upper, lower, internal and external cortices.
Results: It was observed that in the edentulous patients there are significant differences between the measurements of the mandibular canal and the bone cortical, with respect to the dentate patients.
Conclusion: According to this study it was possible to verify that the bone undergoes greater resorption in the edentulous patients, with more marked loss of bone between the mandibular canal and the superior and internal cortices with respect to the dentate patients.
