What type of splint is recommended for stabilizing a replanted avulsed permanent tooth?

  1. Flexible splint (titanium wire/resin) for 2 weeks
  2. Orthodontic brackets and arch wire
  3. No splinting required — allow physiologic mobility
  4. Rigid wire-composite splint for 6–8 weeks
Show answer and explanation

Correct answer: A. Flexible splint (titanium wire/resin) for 2 weeks

IADT guidelines: flexible splint for avulsion — 0.1 mm titanium wire (Ericksson wire) bonded with composite for approximately 2 weeks. Flexible splint allows physiologic PDL movement → better healing. Rigid splints increase replacement resorption/ankylosis risk.
  • A. CORRECT. Flexible splint for 2 weeks = current IADT guideline for avulsed teeth.
  • B. Orthodontic brackets create semi-rigid system — not first choice for traumatic avulsion.
  • C. Splinting IS required — no splinting leads to tooth instability and poor PDL healing.
  • D. Rigid splints increase risk of ankylosis — contraindicated for avulsions. Used for alveolar fractures.
