When should the replacement cord be removed from the sulci?

The removal of the replacement cord from the sulci should occur after preparing the impression material. This timing is important because it allows for an accurate impression by preventing the cord from distorting the areas where the impression will be taken. If the cord is removed too early, it risks collapsing, which could lead to inaccuracies. The process typically involves packing the cord to achieve hemostasis and then preparing the impression material to capture the appropriate detail of the anatomy. Ensuring the cord is removed after the impression material is prepared aligns with best practices in achieving adequate detail and a proper fit for the prosthetic device, contributing to efficient treatment outcomes.
