Abstract: Objective: To study the influence of incisor position on facial profile esthetic inskeletal class II adult femaleduring camouflage treatment. Methods: A Chinese young female with skeletal class II hard and soft tissue was chosen as research object, lateral cephalogram and lateral profile photograph of post-orthodontic treatment were taken in natural head position. Photoshop software was chosen to change the position of incisors, then those changes were reflected to lip based on accepted ratios of soft tissue to hard tissue changes.Finally, 12 different profile pictures were achieved. 37 professional orthodontists and 40 non-professionals were chosen to score for these pictures. Results: The preferable profiles were those with lower incisor inclination of 90 or 92.5 degrees, and those with FA Points of maxillary incisors 1 or 2mm behind the goal anterior limit line(GALL line). Conclusion: In skeletal class II adult orthodontic treatment, attractive soft tissue profiles were achieved when the lower incisor and upper incisor were kept in a labial and lingual tipping position respectively,and the ideal lower incisors labial inclination was kept between 90° and 95°.Excessive labial inclination of lower incisors easilyruin a pleasing smiling appearance.
