简要总结
It is intended to evaluate changes in arch dimensions and incisor inclination as well as changes in the WALA Ridge in no extraction patients treated with interactive self-ligating brackets (Empower®) and passive (Carriere SLX®) at the end of the phase of alignment and leveling. For this, study models and profile radiographs taken before the start of treatment and at the end of the alignment and leveling phase will be evaluated. The parameters to be measured are: intercanine distance, arch depth, upper and lower incisor inclination, and WALA ridge analysis
