Final answer:
Displaced teeth are held in place with a splint for typically 2-4 weeks to allow healing of the periodontal ligaments and stabilization of the teeth. The correct answer to the question is 2-4 weeks, option b). Splinting duration can vary based on injury severity and individual patient needs.
Step-by-step explanation:
When displaced teeth are repositioned, they are typically held in place with a splint. Splinting is an essential part of the dental management following trauma to stabilize the affected teeth. The duration for which a splint is left in place can vary depending on the extent of the injury and other factors related to individual patient care needs. In general, the recommended duration for splinting is approximately 2-4 weeks, which corresponds to option b).
This time allows for sufficient healing of the periodontal ligaments and stabilization of the teeth in their correct anatomical positions. Prolonged splinting beyond the recommended time frame can lead to complications such as ankylosis or root resorption. This period is determined by the consensus guidelines that oral health care professionals follow to ensure the best possible outcome for the patient, with follow-up appointments to monitor progress and make adjustments if necessary.
