1. Maintenance treatment effect: The root stabilization period is the key stage of orthodontic treatment, which can ensure the long-term maintenance of tooth position and occlusal relationship. If this stage is not completely stable, the teeth will move again, which will affect the treatment effect.
2. Prevention of recurrence: In the period of root stability, the position and occlusal relationship of teeth have been basically stable, which is helpful to prevent recurrence after orthodontic treatment. By maintaining good oral hygiene habits and regular review, the therapeutic effect can be further consolidated.
3. Promote dental health: the stable period of root is a critical period for tooth growth and development, and it is also an important stage for dental health. At this stage, the roots of the teeth will gradually develop completely, and the bones around the teeth will be well reconstructed. Therefore, it is very important to maintain the stable period of root to promote tooth health.
