Distalization of the maxillary dentition is necessary for nonextraction Class II treatment, but it is challenging to achieve bodily movement without extrusion of the molars. In such cases, the palatal approach might be the best answer for obtaining these results. Palatal bone thickness and density, and soft tissue thickness are usually able to support temporary anchorage devices (TADs) in adults and adolescents. In this lecture, various challenging cases will be presented where TADs and novel appliances were used, and treatment outcomes will be discussed.
Discuss clinical applications and biomechanical considerations of TADs and novel appliances.
Describe extraction versus distalization.
Describe factors affecting vertical and sagittal control of Class II correction.
