, also known as fangs. Some people also call it maxillary and mandibular protrusion, beak deformity, inverted teeth and so on. Bone tooth protrusion is caused by the protrusion of upper and lower jaws.

, occlusal relationship disorder,

Dysphony and upper and lower lips are at rest.

Unable to shut down naturally.

Wait for a series of performances.

According to the relationship between the teeth and the maxilla, the tooth protrusion can be divided into open jaw type with tooth protrusion and closed jaw type with bone protrusion. If this deformity is found in the early stage of growth and development, it can be corrected by orthodontics. But in adulthood, no matter what type of wire arch orthodontics is not a good choice.

Osteoodontoid protrusion in adulthood is not only tooth protrusion, but also alveolar protrusion.

That is, the maxilla and mandible protrude forward. Once the bone protrudes forward, it can not be recovered by non-surgical methods unless it is completely developed during the growth and development period to prevent the bone from overgrowth. Pulling out a few teeth and applying force with a steel wire bow to force the protruding teeth to rotate backward can change the angle of the teeth and change the appearance to some extent. But in fact, this method can only change the angle of teeth in alveolar bone, but can't make any changes to alveolar bone itself. After orthodontic treatment, when the external force is removed, the angle of the teeth will rebound to varying degrees, which is close to the angle before orthodontics, and the long-term effect is not ideal. In addition, excessive orthodontics will loosen the teeth and may fall off early. Therefore, only surgical plastic surgery is the best choice for adult bony protrusion.
