Evaluation of the Correlation Between the Structural Parameters of Trabecular Bone in CBCT and the Primary Stability of Dental Implants.

This article investigates the correlation between structural parameters of trabecular bone obtained from cone beam computed tomography (CBCT) imaging—specifically fractal dimension (FD) and gray values (GV)—and the primary stability of dental implants measured by insertion torque (IT) and implant stability quotient (ISQ). In a study of 60 patients receiving single implants, significant positive correlations were found between FD and ISQ/IT values, as well as between GV and ISQ/IT values, with higher FD and GV observed in mandibular compared to maxillary sites. The findings suggest that FD and GV derived from CBCT can serve as effective, noninvasive predictors of implant primary stability, potentially aiding presurgical planning. The study emphasizes the need for further research on different implant designs and surgical techniques and proposes integrating FD calculation into CBCT software for clinical use.
