Class 1 - Anterior Openbite
Openbites can be created by habits (thumb or finger sucking), but they are usually associated with difficulty breathing through the nose. And the roof of the mouth is almost always too narrow.
Anterior Openbite - Constricted Upper Jaw
If the upper jaw is not wide enough, there won’t be adequate space for the tongue, so it is forced forward to such an extent that the front teeth can’t come together, and biting through some foods can be impossible.
In adults, it is difficult to achieve profound widening without surgical assistance. In this case, widening the upper jaw, followed by 23 months of full braces was sufficient to provide an good functional bite and a beautiful smile.
Many of these patients find it easier to breathe through their nose after the procedure, and their ability to taste is better. Certainly there has been an improvement in her smile.
