This allows for the greatest change in facial aesthetics and bite function, since both jaws can be moved or tilted in any direction in space.<\/p>\n<p data-start=\"780\" data-end=\"1006\">Compared with single-jaw procedures, the recovery time is slightly longer and the operation is more complex; at the same time, the achievable result is far more striking: a harmonious smile, a more symmetrical face, and easier biting and breathing.<\/p>\n<h3 data-start=\"1013\" data-end=\"1051\">When might Bimax surgery be needed?<\/h3>\n<p data-start=\"1053\" data-end=\"1153\">It is most often recommended when the problem can no longer be corrected with orthodontics alone, for example:<\/p>\n<ul data-start=\"1154\" data-end=\"1410\">\n<li data-start=\"1154\" data-end=\"1214\">\n<p data-start=\"1156\" data-end=\"1214\">a severe jaw discrepancy (Class II or Class III bite),<\/p>\n<\/li>\n<li data-start=\"1215\" data-end=\"1272\">\n<p data-start=\"1217\" data-end=\"1272\">when the lower jaw sits ahead of the upper jaw (Class III),<\/p>\n<\/li>\n<li data-start=\"1273\" data-end=\"1328\">\n<p data-start=\"1275\" data-end=\"1328\">when the upper jaw is too narrow or set too far back,<\/p>\n<\/li>\n<li data-start=\"1329\" data-end=\"1410\">\n<p data-start=\"1331\" data-end=\"1410\">when the aesthetics of the smile and face can only be improved through complex jaw repositioning.<\/p>\n<\/li>\n<\/ul>\n<h3 data-start=\"1417\" data-end=\"1452\">The structure of bimaxillary surgery<\/h3>\n<p data-start=\"1454\" data-end=\"1553\">Bimax surgery actually consists of two separate procedures, which the surgeon performs in a single session.<\/p>\n<h3 data-start=\"1555\" data-end=\"1606\">1. BSSO \u2013 Bilateral Sagittal Split Osteotomy<\/h3>\n<p data-start=\"1607\" data-end=\"1771\">This is the operation on the lower jaw. The surgeon splits the bone behind the last teeth, then moves it into the pre-planned position and fixes it with titanium screws.<\/p>\n<ul data-start=\"1772\" data-end=\"2004\">\n<li data-start=\"1772\" data-end=\"1836\">\n<p data-start=\"1774\" data-end=\"1836\">Most often we achieve the desired result by advancing the jaw forward.<\/p>\n<\/li>\n<li data-start=\"1837\" data-end=\"1927\">\n<p data-start=\"1839\" data-end=\"1927\">The profile improves: the chin comes forward, the double chin is reduced, and the contours of the face become sharper.<\/p>\n<\/li>\n<li data-start=\"1928\" data-end=\"2004\">\n<p data-start=\"1930\" data-end=\"2004\">Closing the mouth becomes easier, and the outward turning of the lower lip can disappear.<\/p>\n<\/li>\n<\/ul>\n<div style=\"width: 1280px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-3012-1\" width=\"1280\" height=\"720\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/foxxi.hu\/wp-content\/uploads\/2025\/09\/BSSO-_-Lower-Jaw-Advancement-Surgery.mp4?_=1\" \/><a href=\"https:\/\/foxxi.hu\/wp-content\/uploads\/2025\/09\/BSSO-_-Lower-Jaw-Advancement-Surgery.mp4\">https:\/\/foxxi.hu\/wp-content\/uploads\/2025\/09\/BSSO-_-Lower-Jaw-Advancement-Surgery.mp4<\/a><\/video><\/div>\n<h3 data-start=\"2006\" data-end=\"2036\">2.
