Controlling orthodontic tooth movement with clear aligners
An updated systematic review regarding efficacy and efficiency
Rossini, Gabrielle / Parrini, Simone / Deregibus, Andrea / Castroflorio, Tommaso
Objective: To update the scientific evidence relating to the efficacy of clear aligner treatment (CAT) in controlling orthodontic tooth movement (OTM).
Materials and methods: International medical databases were searched to identify all peer-reviewed papers potentially relevant to the review. The quality of evidence was ranked using the Swedish Council on Technology Assessment in Health Care Tool criteria.
Results: Twenty relevant articles were selected and the quality of evidence was high for three studies, moderate for 12 studies and low for five studies. Mesio-distal tooth movement revealed the highest predictability, with a molar distalization up to 2.5 mm and space closure of 7 mm performed with good control. Arch expansion is predictable up to 2 mm on molars. Improvements in Little's and PAR Index were reported in mild to severe malocclusions.
Conclusion: The overall quality of available evidence was of moderate/high level. CAT aligns and levels the arches even in severe cases, with efficient control of incisors inclination. Arch expansion and tooth bodily movement are efficiently achievable movements with CAT.
