Presentation Overview
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. The thickness and density of the palatal bone, along with soft tissue thickness, typically provide adequate support for temporary anchorage devices (TADs) in adults and adolescents. In this lecture, various challenging cases will be presented where TADs and clear aligners were used, and the treatment outcomes will be discussed.
Three learning objectives:
Describe common approaches for Class II correction;
Discuss clinical applications and biomechanical considerations of TADs and clear aligners;
Describe maxillary molar distalization relative to third molars.
