Primary Stability Study in Implantology: Correlation of Micromovements to Bone Density and Peak Insertion Torque

In modern implantology, one of the relevant issues regards the assessment of the primary stability. In particular, the role played by micromevements and their effects on various factors such as the intertional torque and bone density are of highest interest. A detailed knowledge of interconnections would be of great clinical relevance in suggesting a more rational application of the immediate loading thus reducing the failure rate. However, the study of the correlations of insertional torque and cortical and cancellous bone densities led to controversial results concerning micromovements and finally the primary stability. We propose here a more focused study on direct evaluations of micromovements.
