Comparison of clinical explants and accelerated hydrolytic aging to improve biostability assessment of silicone-based polyurethanes

Although silicone‐based polyurethanes have demonstrated increased oxidative stability, there have been conflicting reports of the long‐term hydrolytic stability of Optim™ and PurSil® 35 based on recent temperature‐accelerated hydrolysis studies. The goal of the current study was to identify in vitro...
