Background: The demand for orthognathic surgery has increased worldwide. Women with jaw deformity tend to have a worse quality of life than men owing to the deformity's negative effects on body image, low self-esteem, lack of self-confidence, and dissatisfaction with life. Therefore, they wish for more reliable treatment options.

Case Description: A woman aged 25 years and 9 months sought treatment for a convex profile and excessive gingival display caused by a skeletal Class II jaw-base relationship. Gingival exposure was up to 6.5 millimeters at full smile. She chose orthognathic surgery, and the authors performed a 2-piece segmental Le Fort I osteotomy and bilateral sagittal split ramus osteotomy. After active orthodontic treatment, the protrusive profile was improved, and an acceptable occlusion and an attractive smile were achieved.

Practical Implications: It is hoped that 2-piece segmental Le Fort I osteotomy becomes a common treatment option for patients with protrusive profiles and excessive gingival displays.
