OBJECTIVE: This study evaluated the correlation between the initial stability of a dental implant, quantified as the implant stability quotient (ISQ), and the bone-implant contact percentage ( BIC%). STUDY DESIGN: Dental implants were inserted into specimens comprising an artificial cortical shell representing cortical bone and foam bone representing cancellous bone with 4 elastic moduli. Each specimen with an implant was subjected to microcomputed tomography (micro-CT) scanning, from which the 2D and 3D BIC% values were calculated. The values of the Spearman correlation coefficient (r) were calculated between the ISQ and the 2D and 3D BIC% values. RESULTS: Increasing the elasticity of the specimen enhanced the ISQ. There was statistically significant correlation between the ISQ and 3D BIC% values (r = 0.85, P < .0001). However, the correlation between ISQ and 2D BIC% values was not statistically significance (r = 0.42, P = .062). CONCLUSIONS: The initial implant stability was strongly positively correlated with the 3D BIC%.
