[2025-09-30T19:44:49.616782] [PI reasoning] **Exploring diastema retention methods**

To determine the best retention method for orthodontically treated midline diastema, I think a bonded lingual retainer is optimal due to its permanence. Midline diastema closure tends to relapse, primarily because of the labial frenum and proclination issues. A fixed bonded retainer is preferable over a removable Hawley retainer. I should find supportive articles to back this up and ensure I don't mistakenly rely on inaccurate citations.
