Three-dimensional finite element analysis of the effects of different distal-end aligner designs on maxillary premolar distalization
During second premolar distalization in maxillary sequential distalization, removing distal-portion coverage at U7 and U6 effectively reduced mesial relapse of already distalized molars, thereby protecting posterior anchorage. Similarly, during first premolar distalization, to reduce relapse of distalized teeth, distal-portion coverage should be removed at U7, U6, and U5.
