Abstract
As the number of adult patients has been growing, many patients tend not to want to show their appliances to others during treatment. There are two major different types of esthetic orthodontic appliance for such patients. In spite of remarkable development of clear-aligner in terms of its material, structure and wearing protocol, the indication has not been expanded as widely as that of lingual appliance. In lingual technique, it is further more complex to apply each different biomechanics necessary to different symptoms than it is in labial mechanics. Although there has been numerous trials to treat extraction case with esthetic appliance, it can cover only few types of case for extraction treatment. As this case has protrusion with uprighted incisor and gummy smile, we applied antero-posterior lingual retractor (APLR) and clear-aligner combined treatment to carry out root movement and intrusion of upper anterior tooth. The treatment result confirms that this esthetic remedy could be applied to other extreme cases that demand root movement and vertical control in upper anteriors, which could not be improved solely with conventional esthetic appliances.
