Fractal Dimensional Analysis of Trabecular Patterns of the Posterior Edentulous Mandible: A Retrospective Preimplant Study of Pantomographic Images

Abstract Aim: This study evaluated trabecular patterns in posterior mandible using fractal dimensional analysis (FDA) of orthopantamograph (OPG) images for preimplant bone quality. Materials and Methods: Retrospective study of 200 OPGs was performed using Image J software that analyzed mesial, distal, and apical regions of teeth 36 and 46. Results: No significant difference was noted between 36 and 46 in mean trabecular intensity and fractal dimension (FD). Males had significantly higher trabeculae intensity in the mesial region of 36 ( P = 0.003). Females showed higher FDs in 36 (mesial, distal, apical; P = 0.04, P = 0.01, and P = 0.002) and in 46 distal ( P = 0.02). Conclusion: FDA of OPG images is a promising method for evaluating preimplant bone quality variations.
