This chapter aims to answer some of the open questions about treatment outcomes using self-ligating brackets. In particular, the focus is on the analysis of: 1) arch width and tipping after the alignment phase and the end of treatment; 2) alveolar buccal bone remodeling at the end of the alignment phase and the end of treatment; and 3) uprighting and relapse during the retention phase. The results show that the anticipated translation and buccal bone remodeling using active or passive SLBs could not be confirmed either at the end of the alignment phase or the end of treatment. The claimed uprighting of the dentition during the retention phase could not be confirmed either, though the expansion and tipping achieved during treatment generally was retained two years after treatment completion.
