Synchrotron‐Based Analysis of Conical Implant–Abutment Connections Under Mechanical Load: How Embedding Materials Influence the Microgap and Implant Shoulder Deformation
The findings suggest that brass, with higher stiffness than PMMA or bone, does not accurately replicate the mechanical conditions of bone, leading to a difference in microgap behavior and deformation at the implant shoulder, suggesting a difference in the wear mechanism and stress-strain distribution in the surrounding bone. These results question the use of brass in mechanical implant testing and highlight the need for more realistic embedding materials to improve the predictive value of implant testing.
