Effect of orthodontics on the jaw in third-degree malocclusion

In Class III malocclusion, orthodontics causes the teeth and lower jaw to move back and into their normal position. With the use of extraoral devices and in some cases with the intraoral device that was registered in the US Patent Office by Dr. Gamelian, an orthodontist, the upper jaw can be moved forward. In this type of deformity, the patient may need jaw surgery.
