Objective: To evaluate the thickness of the buccal table and interradicular bone septum of molars and its implications for immediate implant placement in the Ecuadorian population using Cone BeaM tomography. Materials and Methods: Observational study, where 72 Cone Beam tomographies from the private Tomographic Center that met the inclusion criteria were selected. The variables to consider were sex, age, thickness of the vestibular bone table, height and width of the interradicular septum. Images were viewed in 1-mm slices with ONDEMAN 3D software for DICON format. The dimensions of the interradicular bone septum were measured: (A) mesiodistal direction, (B) buccolingual direction, (C) height: from the bifurcation point of the roots to the apexes, (D) distance from the apexes to the upper cortex of the mandibular canal, (E) distance from the apex to the floor of the maxillary sinus and F) length of the root trunk from the cementoenamel limit (LAC). In the statistical analysis, Student's t test was used in relation to sex and ANOVA for age (α = 0.05). Results: 52.8% of the tomographies were of women, with a mean age of 38, 27 ±13.75 years, in pieces 16 and 26 they have inadequate space in the maxillary sinus for the implant, with sex there were no differences. significant, even when the spaces and volumes were higher for men, instead the space decreased with age (P value <0.05). Conclusions: Mandibular sites have a greater thickness of the vestibular bone table and interradicular septum compared to maxillary sites, cortical bone densities decrease with advancing age.
