Friends with odontoid process can often get good therapeutic effect as long as they simply put on braces and solve the problem of odontoid process.

Friends with prominent bones may need surgery. So, is it necessary to have surgery to improve bony protrusion?

Not necessarily.

First of all, for adolescent children, the problem of bone protrusion can be improved by orthopedic treatment (non-surgery) of the jaw.

Secondly, for adults, if it is only mild or moderate bony protrusion, it can also be improved by simple orthodontic treatment. Although the position of the jaw can't be changed, the alveolar bone can be slightly reconstructed through the movement of the teeth, and the face shape can be improved to some extent.

It is called "masking therapy", that is, the inclination angle and position of teeth are improved by orthodontic method to cover up the problem of mild and moderate jaw development. How much you can improve depends on your own conditions. For example, the width of alveolar bone determines the range in which teeth can move.

Under suitable conditions, "masking therapy" can still achieve satisfactory results.

However, for adults with severe bony protrusion, "orthodontics+orthognathic surgery" may be a more suitable treatment.
