Classification Case report
The camouflage treatment of skeletal Class III malocclusion is completed by dentoalveolar tooth movement even often needs to combine with maxillary expansion.
In this report, we described the orthodontic camouflage treatment of a 15 y/o male teenager with a severe dental and skeletal Class III malocclusion (ANB -4.5˚), and concave profile with a prognathic mandible and a mild retrusive maxilla. He had severe crowded upper and lower ant. teeth with negative OJ 4 mm, dental ML deviation and narrow maxillary arch with partial post. cross-bite. Because the patient and his parents refused surgery after stopping growth and he had only a little remaining growth, the correction of Class III malocclusion, severe crowding and post. crossbite was achieved successfully by the distalization of lower dentition with bilateral buccal shelf TADs, the buccal movement of upper ant. teeth and maxillary expansion with RPE. Finally, the treatment result showed the canine and molar Class I relationships, normal OJ and OB, well functional occlusion and straight lateral profile.      
「Discussion & Summary」
The mild to moderate severity of Class III malocclusion in adult patients without growth or teenager with almost none growth can be camouflaged by dental compensation. With the advent of TAD, it is possible to increase the range of orthodontic tooth movement that is beneficial to increase the possibility to achieve camouflage treatment for severe Class III malocclusion without surgery.
