Correct answer: A — Flexible splint for 4 weeks

The correct answer is A: Flexible splint for 4 weeks. IADT guidelines specifically recommend flexible (or functional) splinting for lateral luxation of permanent teeth. A flexible splint allows physiological tooth movement, which promotes periodontal ligament and bone healing whilst providing adequate stabilization. The standard duration is 4 weeks. Option C (rigid splint) contradicts IADT guidance—rigid fixation increases the risk of root resorption and complications. Option D (2 weeks) is too short; 4 weeks is required for adequate periosteal reattachment. Option E combines two errors (rigid and too long). Option B is incorrect as IADT guidelines mandate splinting for all luxations to prevent secondary displacement and protect healing tissues.
