What is the primary indication for a supracrestal fibrotomy?

The primary indication for a supracrestal fibrotomy is to reduce the possibility of relapse for a severely rotated tooth or teeth. This procedure is specifically designed to address the challenges of maintaining the position of teeth that have undergone significant orthodontic movement, particularly those that were heavily rotated prior to treatment. By performing a supracrestal fibrotomy, the excess gingival fiber attachments around the tooth are severed, allowing for more freedom of movement and positioning, which ultimately helps to maintain the new alignment after orthodontic treatment.

While the procedure can also have implications for crowded incisors, the most direct and primary focus is on managing the stability of teeth that have been rotated into a more functional position. The reason why this option is preferred over simply stating that it reduces the tendency for all crowded incisors to relapse is that the mechanics behind rotation and crowding are distinct, and the concerns related to relapse can vary based on the specific orthodontic scenario. Thus, recognizing the unique role of supracrestal fibrotomy in relation to rotated teeth is crucial in understanding its primary indication.
