ABSTRACT

Aim: To explore the relationship between primary implant stability and cortical bone thickness.
Materials and Methods: Twenty-three implants were inserted into fresh sheep bone. The cortical width of implant recipient sites was determined using cone-beam computed tomography (CBCT). The maximum insertion torque value of each implant was recorded. Implant stability was measured using an Osstell system. Spearman's correlation coefficient was used to evaluate the correlations among variables.
Results: The cortical width and Hounsfield unit mean values were 3.3 ± 1.0 (mm) and 1468.5 ± 272.3, respectively. The correlation between cortical bone thickness and Osstell value was not statistically significant (p > 0.01).
Conclusion: The cortical bone thickness evaluated using CBCT had no correlation with the primary stability of dental implants.
