Effectiveness and Stability of Treatment with Orthodontics Clear Aligners: What Evidence?

Clear aligners, as a transparent and removable appliance, offer an alternative to conventional fixed appliance patients with high demands for esthetics comfort. Only few investigations have focused on the efficacy of clear aligner therapy in controlling orthodontic tooth movement. Furthermore, stability after treatment has not been thoroughly investigated. The purpose this chapter was update knowledge available evidence about effectiveness aligners non-growing subjects. Searches made different databases from January 2015 2021. Relevant articles that met inclusion criteria were selected. level studies moderate. vertical movements difficult accomplish. Mesiodistal tipping showed most predictability (82.5%) followed by vestibulolingual tipping. Molar distalization also recorded highest accuracy. Derotation accomplish especially rounded teeth. achieving simulated transverse goals 45%. assessed only two studies. Refinements are likely needed almost all cases ensure retention period using specific protocol is necessary.
