Expanders

Schwartz Appliance

Expanders1The Schwartz Appliance is a removable expansion appliance primarily used on the lower arch in order to expand the arch and create needed additional space for the permanent teeth. Treatment time in the Schwartz Appliance is approximately nine months but will vary based on individual needs of the patient. If both the upper and lower arches require expansion, we may use the Schwartz along with a Rapid Palatal Expander in order to coordinate the expansion of both arches.

 

Rapid Palatal Expander

Expanders2Attached to the upper molars through bonding or by cemented bands, the Rapid Palatal Expander is an orthodontic device used to create a wider space in the upper jaw. It is typically used when the upper jaw is too narrow for the lower jaw or when the upper teeth are crowded or blocked out of the dental arch.

When patients are still growing, their connective tissue between the left and right halves of their upper jaw is very responsive to expansion. By simply activating the expander through turning a screw in the center, with a special key we provide, a gradual outward pressure is placed on the left and right halves of the upper jaw. This pressure causes an increased amount of bone to grow between the right and left halves of the jaw, ultimately resulting in an increased width.
