Proper age to cure maxillary retrusion

The cure works better at young ages. In short words, you can say that the younger the patients are, the better the results get!

The reason that the treatment for this disorder is recommended to do at young ages is that the younger patients, especially kids, have softer mandibular bones. This makes the orthodontist move the upper jaw forward easily.

It boosts the maxilla’s growth and after moving maxilla bone forward, it comes to teeth. At this level, teeth are organized by fixed orthodontics. Consequently, the older the patient is, the longer the treatment takes, and also the jaw operation probability is higher. However, the younger the patients are, the better the treatment works, and the jaw operation probability is less. The proper age to do orthodontics for misaligned upper jaw is from 7 to 12.
