Protruding mouth correction

A protruding mouth refers to a condition when the mouth sticks out over the nose or nose and chin at the same time. If the mouth sticks out, usually it means that the teeth and gums also protrude, revealing the gums and teeth when smiling (gummy smile). This can cause the development of wrinkles on the chin and deep smile lines. Not only dental braces require a longer treatment period, but it’s difficult to get satisfactory and visible improvements with dental braces if your protruding mouth is caused by your gum protrusion. This condition can be improved with ASO (Anterior Segmental Osteotomy) is a protruding mouth correction surgery. In almost all cases, protruding mouth correction surgery has to be performed with genioplasty. As protruding mouth correction surgery requires hyper-precise pre-surgery preparations, patients should come 1 week before surgery.
