Objective:
This study aimed to evaluate the influence of trabecular bone microstructure on the accuracy of dental implant placement using dynamic navigation.
Study Design:
Thirty-seven implants were placed in 35 patients. Bone biopsies were analyzed to measure bone volume fraction (BV/TV), trabecular thickness (Tb.Th), number (Tb.N), and separation (Tb.Sp). Implant deviations were assessed with navigation software.
Results:
BV/TV showed a significant negative correlation with apical (r = -0.396, P < .05) and angular deviation (r = -0.402, P < .05), but not with coronal deviation. Critically, no other parameters (Tb.Th, Tb.N, Tb.Sp) demonstrated any significant correlation with implant positioning accuracy (all P > .05). Multivariate analysis confirmed BV/TV as the sole significant predictor of angular deviation (β = -0.079, P < .05).
Conclusion:
While higher bone volume fraction improves angular accuracy, other trabecular microstrctural parameters do not significantly influence placement precision under dynamic navigation.
