Long-Term Aging Effects of Breast Implant Materials

Breast prostheses are widely used for both aesthetic and medical purposes. Unless clinical or subjective factors impose early removal, these implants can remain in place for extended periods of time, often exceeding 20 years. Understanding the expected changes in their performance over time, in addition to medical issues, is crucial for decisions regarding potential removal or replacement. This study investigates the long-term aging effects on silicone breast implants by evaluating changes in the mechanical properties of the elastomeric shell and the viscoelastic behavior of the inner gel. Accelerated aging tests were conducted at different temperatures, and the data were analyzed using established predictive models to estimate mechanical performance over extended periods. These results provide valuable insights into the expected durability and lifespan of breast implants, supporting improved predictions of long-term safety.
