[2025-09-30T13:57:17.059904] [PI reasoning] **Analyzing prosthodontics question**

I need to address a question about removable partial dentures, specifically regarding the first step in major connector construction. I’m considering the options: A) Design of stress-bearing areas, B) Non-stress-bearing areas, C) Marking the strapline’s outline, and D) Selection of strap type. The design sequence usually starts with selecting the major connector type after surveying the cast. I think the answer might be C, as marking the outline on the cast provides crucial strap boundaries.

[2025-09-30T13:58:43.520023] [PI reasoning] **Exploring major connector steps**

I’m finding that the search results aren’t quite hitting the mark for this specialized dental prosthodontic question. I’m reasoning through the process of constructing a major connector. The first step involves marking the outline of the strap line on the cast, followed by placing relief wax. While aspects like stress-bearing areas and selecting the strap type play a role, they likely come later in the design phase. So, I’ll reinforce that marking the outline is the very first step.
