[Evaluation of profile aesthetics of skeletal Class Ⅱ patients with different treatment methods].

Purpose: To study the aesthetic appearance of skeletal Class Ⅱ patients with maxillary protrusion and mandibular retrusion treated with different methods.

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.

Results: 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.

Conclusions: 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.
