Posterior Crossbite
 

A posterior crossbite is a common orthodontic problem for children and it occurs when the upper jaw does not grow wide enough for the upper teeth to fit properly with the lower teeth. A patient with a narrow upper jaw usually shifts the lower jaw to one side in order to chew adequately. If not corrected this can cause the lower jaw to grow to one side, causing a facial asymmetry with the chin skewed to one side. A posterior crossbite is usually corrected with a palatal expander which pushes the two bones of the upper jaw apart to increase its width. This type of expansion is called skeletal expansion because it expands the bones, whereas dental expansion only widens the teeth within the existing bone. Skeletal expansion is relatively stable but dental expansion is more likely to re-constrict after the appliance is removed. Dental expansion can also cause bone loss and gum recession on the roots of the teeth. Some orthodontists like to do skeletal expansion at a very young age, even before a child has any permanent teeth. Dr. Rushing usually prefers to wait until the patient is six or seven years old, after the permanent incisors and first molars have erupted. Click Palatal Expansion for more information.

Skeletal expansion of the palate must be done when patient is young, because after the palatal suture fuses together, skeletal expansion is not possible without also doing surgery on the palate.
