Tongue pressures and tooth stability after anterior maxillary osteotomy.
Tongue pressures against the maxillary dentition during swallowing were measured in a series of ten patients who underwent anterior maxillary osteotomy for correction of protrusion. In these patients, tongue pressures were low initially, especially pressures by the sides of the tongue in the molar region. After surgical retraction of the incisors, tongue pressures increased, but the increases brought pressures up to normal levels from the previous abnormally low values. The data are consistent with the view that function (swallowing) adapts to oral form, rather than the other way around.
