What is an Expander?

What is an Expander?

Expanders are used for certain conditions when the upper jaw or palate is narrow. Expandtion can be done before adulthood, the palate is actually two seprate bones connected down the middle by a non-bony suture.

Fixed Rapid Palatal Expander

Advantages of this technique include more room to align the teeth, a broader more esthetic smile, a more stable final result and sometimes even easier to breathing through your nose!
Relatively heavy forces applied quickly (to minimize orthodontic tooth movement) will cause the two palatal bones to separate.  After a period of time new bone fills in and preserves the increased width of upper jaw.

A typical expansion procedure involoves activation of the appliance once a day for about 3-4 weeks.  This is followed by 3-4 months of stabilization before the appliance is removed.

For most patients it is the size and bulkiness of the expander that make it the most uncomfortable. Soreness of teeth can be expected and, as the appliance expands the mid facial bones, some discomfort under the eyes and around the nose may occur.  A large space can be expected to open between the front, center teeth.  This is because one tooth goes with the right side the other goes with the left side, each is a seprate bone.  This movement stretches the gum tissue between the incisors; and over a period of a few months they will be pulled back together.  Fixed (glued in) appliances are almost always necessary to acheive an ideal alignment.

When expanding:

If you experience a GREAT deal of pain activating the appliance, you are unable to turn the screw, or if the appliance becomes loose we ask our patients to call our office and make an appointment IMMEDIATLEY!

If you are unable to make the observation appointment during the expansion phase DO NOT continue to expand past your appointment date.

The most important part: Might not be fun, but it is FAST!
