Why does orthodontics take so long?

Everyone's tooth deformity is different, and the orthodontic equipment and orthodontic scheme are different, so the orthodontic time is different. Orthodontic time is influenced by many factors, mainly as follows:

1. Age factor: There is a great difference in orthodontic time between minors and adults. Because minors are in the stage of growth and development, the plasticity of jaws and alveolar bones is high, teeth move faster and the orthodontic time is relatively short. However, due to the complete development of adults, the plasticity of jaw and alveolar bone is not high, and the teeth move slowly, which takes a long time to correct.

2. Degree of tooth deformity: the treatment time of complex malocclusion is longer than that of simple malocclusion, and the correction time of skeletal deformity is longer than that of simple tooth deformity, so it may be necessary to wear tooth retainer for life.

3. Orthodontic methods: Traditional orthodontics takes a long time, and self-ligating bracket orthodontics can be shortened by about 3~6 months compared with traditional orthodontics. However, because there is no adhesive bracket and complicated archwire adjustment, the clinical operation is greatly simplified, and the whole correction process saves time and effort.

4. The strength of orthodontics: The teeth must move smoothly under the action of proper orthodontic force. Too little force does not work, and too much force may cause periodontal tissue damage. After the injury, the tissue needs time to repair, thus delaying the tooth movement.
