Explanation lettering: D = shown as C · E = shown as D · C = shown as E
UK guidance (SDCEP, NHS trusts) and IADT consensus recommend a flexible composite-wire splint for 2–4 weeks following subluxation of a permanent tooth when splinting is necessary. Option A (flexible, 2 weeks) is the standard for uncomplicated displacement injuries. Flexible splinting preserves physiologic tooth mobility, which is essential for periodontal and pulp healing and reduces the risk of ankylosis and external root resorption. Rigid splints (B, D) compromise healing and are not recommended. Option E exceeds the established duration window. Option C ignores the clinical reality that mobile subluxated teeth require splinting for stability and healing.
