Polyvinyl siloxane impressions were taken after bracket debonding (T1) and 1 week later (T2) and digitally scanned. During this period no retention was used. The digital casts were superimposed on structures of the hard palate. Translation and rotation of the first molars, canines, and central incisors were recorded. Additionally, movement of these teeth was assessed from the beginning (T0) until the end of treatment (T1). The correlation between the post-treatment relapse (T1\u2013T2) and tooth movement during treatment (T0\u2013T1) was investigated via the Spearman correlation coefficient.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Relapse was detected and reflected changes in tooth position during treatment. For the first molars (right, left) the correlation between treatment and post-treatment tooth movement was evident in the transverse direction (r = \u22120.38, P = 0.020; r = \u22120.32, P = 0.052), tipping (r = \u22120.40, P = 0.015; r = \u22120.34, P = 0.034) and the antero-posterior direction (r = \u22120.31, P = 0.061; r = \u22120.36, P = 0.027); for the canines (right and left), as rotation around their long axis (r = \u22120.55, P = 0.003; r = \u22120.58, P = 0.002); for central incisors (right and left) in the antero-posterior direction (r = \u22120.55, P = 0.000; r = \u22120.48, P = 0.03), transverse direction (r = \u22120.43, P = 0.07; r = \u22120.32, P = 0.047), and rotation around their long axis (r = \u22120.53, P = 0.001; r = \u22120.28, P = 0.089).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Post-treatment changes in tooth position were mostly related to tooth movement during treatment.
