Purpose: This study is designed to investigate the relationship between stability by impact response frequency (SPF) and 3D bone micro parameters.

Materials and methods: The developed stability measurement method using analog inductive sensor was utilized to acquire the movement of implant models. 23 dental implantation models using pig rib bone samples were used. The SPF results from implantation models were compared with 3D micro parameters from micro-CT images. The data were analyzed by the SPSS program for linear regression.

Results: Our analysis clearly revealed that a strong positive correlation between SPF values and bone microstructure parameters including BV/TV, BV, BS, IS, BSD, Tb.Th, and Tb.N. On the other hand, there was a negative correlation between SPF values and bone microstructure parameters including BD/BW and Tb.Sp. Conclusion: This work reported the primary implant stability by impact response frequency and 3D bone parameters using pig rib bone.The results indicate that SPF strongly correlates with bone parameters. Based on the present results, further studies should be conducted to identify the correlation between SPF and histological parameters of bone in human samples including more specimens.
