[2025-10-01T18:27:29.638598] [PI reasoning] **Analyzing Gjessing springs**

I’m thinking about the Gjessing canine retraction springs. It seems the Gjessing spring may be made from 0.16x0.22 stainless steel. I recall that the Gjessing retractor is 0.17x0.25 TMA, which could apply here. Among the options given, the textbook suggests that the correct size is 0.17x0.25 TMA wire, making option C the likely answer. I should verify this quickly with a search just to be sure.

[2025-10-01T18:27:50.324339] [PI reasoning] **Evaluating material specifications**

I noticed that the search didn’t capture certain details, but the Dincer article mentions a rectangular dimension of 0.016 x 0.022 inches, likely stainless steel. I want to check Gjessing's original invention next. I think the original retraction spring might have been made from 0.017 x 0.025 inches TMA, but hold on—TMA wasn’t available in 1973. It seems TMA (beta titanium) was introduced in the 1980s by Marcotte. Gjessing's study from 1978 suggests the spring was possibly 0.016 x 0.025 inches stainless steel.
