Nine clients who underwent <jats:styled-content style=\"fixed-case\">SSRO<\/jats:styled-content> for mandibular setback and seven control subjects were participated in this study. Tongue\u2013palatal contact patterns for \/t\/, \/s\/ and \/k\/ production were investigated using <jats:styled-content style=\"fixed-case\">EPG<\/jats:styled-content> before surgery and 3 months after surgery. The mean value of whole total of palate contact (<jats:styled-content style=\"fixed-case\">WT<\/jats:styled-content>) in the maximum contact frame was examined before and after <jats:styled-content style=\"fixed-case\">SSRO<\/jats:styled-content>. The correlation quantity between the change of center of gravity (<jats:styled-content style=\"fixed-case\">COG<\/jats:styled-content>) value and the amount of mandibular setback was also evaluated. The mean value of <jats:styled-content style=\"fixed-case\">WT<\/jats:styled-content> for \/t\/ and \/s\/ significantly increased after <jats:styled-content style=\"fixed-case\">SSRO<\/jats:styled-content>, and the <jats:styled-content style=\"fixed-case\">EPG<\/jats:styled-content> pattern became normal. However, a remarkable change in <jats:styled-content style=\"fixed-case\">WT<\/jats:styled-content> for \/k\/ was not observed, and the mean value was significantly larger in the <jats:styled-content style=\"fixed-case\">SSRO<\/jats:styled-content> group before and after surgery than in the control group. A negative correlation between <jats:styled-content style=\"fixed-case\">COG<\/jats:styled-content> variation and the amount of mandibular setback for \/t\/ and positive correlation for \/s\/ was observed. This study demonstrated that tongue\u2013palatal contact patterns for \/t\/ and \/s\/ articulation improved clearly after <jats:styled-content style=\"fixed-case\">SSRO<\/jats:styled-content>. There was a significant correlation between <jats:styled-content style=\"fixed-case\">COG<\/jats:styled-content> variation and the amount of mandibular setback. However, no significant change was detected through perceptual assessment before and after <jats:styled-content style=\"fixed-case\">SSRO<\/jats:styled-content>. Further investigation is needed to determine whether these results will change over time.<\/jats:p>","DOI":"10.1111\/joor.12530","type":"journal-article","created":{"date-parts":[[2017,6,5]],"date-time":"2017-06-05T15:42:41Z","timestamp":1496677361000},"page":"673-682","source":"Crossref","is-referenced-by-count":9,"title":["Tongue\u2013palatal contact changes in patients with skeletal mandibular prognathism after sagittal split ramus osteotomy: an electropalatography study"],"prefix":"10.1111","volume":"44","author":[{"given":"S.","family":"Kojima","sequence":"first","affiliation":[{"name":"Department of Orthodontics, Applied Life Sciences Hiroshima University Institute of Biomedical &amp;
