A palatal expander gradually widens the upper jaw (maxillary expansion) to create more space in the mouth.
During childhood, Dr. Windhorst can take full advantage of a child's natural growth to effectively prevent or correct malocclusions.
Before puberty, the upper jaw develops as two separate halves that can be easily and gently separated within several months. The upper jaw fuses together completely after puberty.
In addition to correcting malocclusions, maxillary expansion can improve breathing and enhance the smile. Expansion also limits the amount of teeth that need to be extracted to create space.
Maxillary expansion is necessary if a child is experiencing:
A palatal expander is precisely customized for each patient. The appliance fits over several top teeth at the back of the mouth. It has two halves which are connected in the middle by a spring. Once the expander is placed in the mouth, the spring is activated and does not require any additional activation.
We will monitor the patient to make sure the expansion is progressing, and remove the expander once a suitable amount of expansion has been achieved.Occasionally, we have to use a screw-activated expander. A special key is used to turn the screw a small amount every day. This creates tension at the junction of the palatal bones, stimulating them to progressively move apart.
After the upper jaw is widened, the appliance must be worn a few more months so new bone can form in the gap and stabilize the expansion. Expanders are typically worn for 3-6 months.
During treatment, a gap may develop between the front teeth. This is normal and indicates that the appliance is widening the jaw as desired. After expansion, the permanent teeth will be perfectly aligned with no spaces between them.
