[2025-10-02T05:42:31.508881] [PI reasoning] **Clarifying denture techniques**

I’m considering the differences between relining and rebasing dentures. Relining means adding a new layer of resin to the tissue surface, which helps the fit without impacting the occlusal relation. Rebasing, on the other hand, involves replacing the entire denture base while keeping the occlusal relationships intact. So, the answer is that rebasing affects the entire denture base. A concise reasoning should suffice here, and no major literature search seems necessary. However, I'll double-check the definitions in articles or textbooks for accuracy.
