Join me for part 2, where Jae Park describes how to plan either extrusion or intrusion movements, the key evidence around AOB closure and TADs, aligners and orthognathic surgery.

Chris Chang describes the use of aligners (Invisalign), and how to resolve common aligner issues and incorporate TADs to achieve predictable outcomes. Aligners work as a pushing appliance: · Pushing surface (active surface) should be at 90 degrees to the direction of tooth movement. · Pulling movements can be achieved through combining with TADs. Reduced aligner predictability: 1. Distalisation 2....
