This study aims to assess the morphometry of posterior mandibular edentulous sites using CBCT and evaluate implant placement feasibility.
Retrospective analysis utilizing cone-beam computed tomography (CBCT) measurements.
Involves 45 individuals with 252 posterior mandibular edentulous sites assessed for residual bone height and ridge dimensions.
Used linear mixed-effects models to account for patient-level clustering during analysis.
Mean residual bone height was highest in the first premolar region (13.56 mm) and lowest in the second molar (12.09 mm).
Standard implant placement was feasible at 47.6% of sites, while horizontal augmentation was needed in 33.3% of sites.
Significant variations were observed among different posterior regions for ridge width and concavity parameters (p < 0.001).
