Abstract
To study the aesthetic appearance of skeletal Class Ⅱ patients with maxillary protrusion and mandibular retrusion treated with different methods. The facial profile photographs and lateral cephalometric radiographs of a Chinese woman suffering from skeletal Class Ⅱ with maxillary protrusion and mandibular retrusion was digitized.The digital images were modified to obtain orthodontic compensatory treatment, genioplasty with different advancement ranges and orthognathic treatment comprising 6 profiles by Photoshop software，orthodontic professionals and non-professionals were chosen to score the pictures. Post hoc tests were done with ANONA and the Student Keuls method to analyze the data Using SPSS22.0 software package. The profile with the highest score was the picture treated by orthognathic and orthodontic treatment. The profile with genioplasty (advancement of 4 mm) took the second place. When the advancement distance of genioplasty was 8 mm, the score was under the score of orthodontic compensatory treatment profile. Orthognathic-orthodontic treatment of skeletal Class Ⅱ is still the best treatment option to improve facial aesthetics. Genioplasty, as a adjuvant treatment, improves the appearance based on compensatory orthodontic treatment to some extent, but not comparable to orthognathic-orthodontic treatment.
