[2025-10-02T07:31:38.918471] [PI reasoning] **Researching pier abutments**

I’m looking into the dental prosthodontics concept of "pier abutment." Essentially, it's a natural tooth that acts as a support for a fixed partial denture, placed between terminal abutments with edentulous spaces on both sides. The answer seems to be B, indicating there are spaces on both sides. Next, I need to craft some reasoning for this, along with a citation. I’ll perform a search to find supporting evidence for my answer.
