Abstract

Abstract

Objectives: The aim of this systematic review is to review all the evidence available about the efficacy of the Invisalign® system in upper incisors’ movements in the last decade, since 2010.

Methods: A search strategy was performed in a number of databases to include as many studies as possible. MEDLINE, Scopus, Pubmed and the Cochrane Oral Health databases were searched. 10 studies were included in the systematic review.

Results: Incisor rotation and extrusion seemed to be the most predictable movements (all results had a predictability score of more than 50%), whilst torque and translation seemed to be the most difficult to be performed (most results were under 50%). Intrusion movements seemed also to be overcorrected (142.4%), resulting in possible apex resorption if not calibrated correctly.

Conclusions: Single isolated dental movements seem to be predictable with the Invisalign® system, but major complex movements seem to be more unpredictable. The most predictable types of movements seem to be incisor rotation and extrusion, whilst the least predictable seem to be incisor torque and translation. Further studies are needed to examine further the predictability of the Invisalign® system considering more variables influencing the results of the studies.
