1. The Tongue
The forces of the tongue, lips and surrounding facial muscles are sufficient to move teeth into any position.
Soft Tissue Dysfunction
Understanding Soft Tissue Dysfunction
Once soft tissue dysfunction is correctly diagnosed and treated, the results of any orthodontic treatment are improved, particularly in terms of case stability.
Correcting these bad oral habits allows a practitioner to align teeth much more efficiently, without high mechanical forces being needed.
By placing the tongue up into the correct position in the maxilla the arch-form is also improved. When looking at the arch-form, start to think about how the dysfunction of the muscles - the tongue, cheeks and lips, might have caused the arch to be this shape. The teeth are in their positions because of the function of the tongue, cheeks and lips.
