What is the recommended splinting duration for avulsion, subluxation (bump without dislocation), and extrusive luxation?
Correct Answer:
4 weeks
Explanation:
Stabilizing the tooth after significant trauma gives the periodontal ligament and surrounding bone time to heal and reduces the risk of further damage from movement. Avulsion, subluxation, and extrusive luxation all involve notable disruption of the supporting tissues, so a longer, but still flexible, splinting period is recommended to allow proper healing and reattachment. Four weeks of flexible splinting provides enough time for the tissues to recover and for the tooth to regain stable function, while avoiding the problems that come with too-short immobilization (continued mobility and trauma) or too-long immobilization (increased risk of ankylosis and other complications).
