Objectives. The aim of this study is to analyze the electromyographic and electrognatographic results deriving from 10 patients subjected to rapid palatal expansion, before and after the expansion, and to find out a relationship between the results. Materials and methods. The sample consisted of 10 children (6 females and 4 males; range: 9-13 years) with bilateral maxillary hypoplasia, and subjected to an electromyographic and electrognatographic exam before and after rapid palatal expansion. Results. By analyzing the results, it is possible to observe an increased electrical activity of the masticatory muscles (right and left masseter, right and left anterior temporalis) both in rest position and during the exercises of the different acquisitions, at the end of the active phase of the rapid palatal expansion. Conclusions. After the rapid palatal expansion the muscular activity increases: the expansion, though it does not act directly on the masticatory muscles, produces important changes in the muscular tone.
