Distalization of the maxillary dentition is necessary for non-extraction 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.
Describe common approaches for Class II correction.
Discuss clinical applications and biomechanical considerations of TADs and novel appliances.
Describe maxillary molar distalization relative to third molars.
