Title: Closing of the space after extraction. Lingual vs Invisalign, biomechanics comparison

The aesthetic treatment requests from adults are increasing more and more these days. Traditionally, lingual techniques were the only ones to satisfy that need. New therapies based on the use of aligners are now proposed. 

Can they answer biomechanically all clinical situations? An analysis between biomechanics of lingual treatment and of treatments using aligners compare the effectiveness of each of these devices addresses the different types of desired movements.
