A treatment objective of upper molar distalisation may often be indicated for the correc-tion of a dentoalveolar Class II malocclusion with an associated increased overjet and/or anterior crowding. Due to aesthetic concerns and the duration of treatment, molar distali-sation using headgear is unacceptable for many patients. This has resulted in a preference for purely intra-oral distalisation appliances which require minimal patient cooperation. Unfortunately, most conventional devices for non-compliance maxillary molar distalisa-tion produce unwanted side effects, such as anchorage loss. To minimise or eliminate anchorage loss related to the anterior teeth, skeletal anchorage has been integrated into distalization appliances. Especially for aligner treatment, the use of mini-implant borne sliders seems very recommendable due to the advantage of a bodily distalization. In this lecture, different design of distalization mechanics are discussed.
Learning Objectives:
Identify the best insertion sites for TAD borne distalization appliances.
Identify pros and cons of different designs of a TAD borne distalizer.
