RPE (2 banded)

This adaptation of the RPE is a good alternative when rapid palatal expansion is desired but the patient is in mixed dentition or banding of the first bicuspids might be a problem. Due to the rigid nature of these appliances, the 2 banded version is also a good choice in cases with a difficult path of insertion. The anterior arms of the expansion screw are soldered directly to the lingual wires thus eliminating the need for bicuspid bands.
