When is orthognathic surgery needed?

In general, person with malocclusion or issue with jawbone which affects physical appearance requires the treatment of orthognathic surgery.

Malocclusion frequently causes buck-toothed, underbite, bird’s beak, crooked face and moon-shaped face. However, there are other effects of malocclusion. For instance, upper and lower teeth do not touch each other (openbite), buccual or lingual position biting (crossbite), and asymmetric of occlusal plane. These conditions may lead to other issues with eating, talking, breathing, temporomandibular joint and social adaptability.

Malocclusion may cause a person to have difficulty in cutting or chewing food because the upper and lower teeth do not make contact. Furthermore, dislocation of upper/lower lips and tongue may result in the inability to pronounce certain words. In some cases, person with malocclusion may have abnormal jawbone motion in order to compromise the misalignment of their occlusion. Subsequently, this may lead to chronic headache and chronic temporomandibular joint disorder. Moreover, the psychological influences should not be overlooked as malocclusion often lead to issues with social adaptability because it greatly affects facial appearance.

All of us are unwilling to see another person surrendering their deserved social enjoyment due to the facial appearance which does not meet their expectation. Face is the window leading to the world and you should show the world who you really are.
