A 13-year-old female presented with a class I malocclusion on a mild skeletal class II pattern with average vertical dimensions complicated by moderate upper arch crowding, palatal displacement of the UL2 and a localized crossbite

Initially, Headgear was used but compliance was poor. It was therefore decided to remove both maxillary second premolars to recreate space for maxillary arch alignment.

Therefore, Self-ligating brackets (SLBs) were used in this case after extractions. What are SLBs and what are the advantages of these systems? Why has glass ionomer cement been placed on the maxillary first molars? What is the final buccal segment relationship
