Form follows function. 👅🦷
We talk a lot about closing an open bite, but what about keeping it closed?
One study looked at 76 people with dental anterior open bites who were referred for orofacial myofunctional therapy (OMT) at different points in their orthodontic journey.
• 27 people received both orthodontic treatment (or retreatment) and OMT.
• 49 people had previously had orthodontic treatment but experienced an open-bite relapse.
And the difference was pretty interesting.
Those who received orthodontic treatment along with OMT had much less relapse than those who had orthodontic treatment alone.
The average relapse was about 0.5 mm in the OMT group compared with 3.4 mm in the orthodontic-only group.
The researchers also found that things like forward tongue posture and tongue-thrust swallowing were associated with open-bite relapse, and that speech errors and oral habits could often be addressed through OMT.
So this is why I believe it’s so important to look beyond just the position of the teeth.
If the function that contributed to the problem isn't addressed, the teeth may be fighting against those same forces after orthodontic treatment.
It's not about choosing orthodontics OR myofunctional therapy.
Sometimes it's about orthodontics AND myofunctional therapy working together. ❤️
Form follows function.
Correct the dysfunction. Support the form long-term.
