Identifying a Bad Bite
Overbites, Underbites, Pushed in front teeth, Crossbites, Openbites, and controlling the tongue.
The facial profile commonly associated with a deep overbite is that of a receded lower jaw. This could mean that the lower jaw is underdeveloped at this age, or is displaced in a “backward” relationship compromising the integrity of the developing jaw joint. Images of the jaw joint are recommended to assess the
Early intervention provides the best outcome without comprise or surgery:
The Openbite
Well, what about the opposite extreme………………………………the openbite?
The six views below represent various openbite conditions; most of which are due to abnormal tongue position and airway obstruction. Inadequate vertical overlap of the upper front teeth over the lower front teeth can be caused by digital habits as well, but the most common cause is the airway/tongue position relationship.
For comparison:
Crossbites: From Simple To Complex
Simple
The “Underbite” or anterior crossbite: more complex
This young 5 ½ year old presented with a concave facial profile with a prominent chin. Her front teeth were in a crossbite relationship. Failure to address this problem at a young age when the specialist can “ re-direct” growth, will predispose a patient to a more significant imbalance involving the jaw bones, teeth, and jaw joints necessitating surgical assistance at a later date when growth has been completed. This is a good example of the FORM <--> FUNCTION model of growth and development.
Class III before and after case
Oftentimes, a crossbite can occur just on one side, which will cause the lower jaw to be positioned to the right or the left, but not on center. If the crossbite persists, the lower jaw will grow more on one side than the other leading to a jaw asymmetry requiring surgical assistance for correction
Again, facial profiling:
