A randomised controlled clinical trial to investigate the rates of alignment of the upper and lower labial segments using conventional, active and passive self-ligating orthodontic brackets

The aims of this project were twofold. Firstly to compare the measurement error using digital Vernier callipers and a 3D laser scanner when using Little's Index of Irregularity on plaster study models. Secondly to establish whether the use of active or passive selfligating brackets results in faster initial tooth alignment than the use of conventional orthodontic brackets.
