Modifications to consider to aligner

o Change attachment – changes tooth shape

o Change aligner shape – e.g. power ridge

o Change sequence of tooth movement

· Aligner force should be directed perpendicular to the resultant tooth movement required

· Vertical control is key

o if not can result in heavy anterior contact – curve of spee due to loss of vertical anchorage and a LATERAL OPENBITE

o Resolve with anterior intrusion

· Deep bite cases should be over treated to AOBs

· Clincheck is a force delivery representation, not a virtual treatment objective

· AOB cases

o Attachments on the occlusal aspect without composite, aids intrusion

· Class 3

o TADs in buccal shelf region
