ORTHODONTIC ALIGNMENT DEVICES WITH PALATAL CONTOUR ANCHORAGE FEATURES

Abstract: an orthodontic alignment device can have a palatal contour anchorage (pca) feature that generally matches the shape of the patient's hard pallet. this pca feature may be built slightly off-set to deliberately push against the patient's palate and/or gingiva to provide anchorage support of staged translation of the teeth. by transferring the required anchorage away from the teeth and onto the palate, through the pca feature, the adjacent teeth are no longer subjected to unwanted side effects of reaction forces.
