Ask a Therapist: Jaw Stability Protocol for Severe Underbite

Posted by Deborah Grauzam on

Hi Therapists,


What do I do for a 19 year old student with a severe underbite (a gap of ½ inch between top and bottom teeth) when trying to use the jaw stability protocol?


Thank you 


When you are working on the Bite Blocks for jaw stability and the Bite Tube hierarchy, you will want to make sure that you have optimal bite posture first. You will judge optimal bite posture from the back molars. From your email it sounds as if his under bite is structural rather than functional. In this case you will work with the bite blocks and chew tubes in his structural position. Unless he has orthodontic work you will not be able to change structure.

I hope this helps. Please let me know if you have any further questions.
