Accuracy and Stability of Clear Aligner Treatment: A Systematic Review.

This systematic review evaluates the long-term stability and retention of clear aligner treatment, focusing on factors like aligner compliance, attachment use, and treatment duration. Following PRISMA guidelines, we searched electronic databases and manual sources, identifying 112 records and narrowing down to six relevant studies. These studies compared clear aligners to traditional braces, highlighting their effectiveness, especially for mild crowding and anterior movements. Clear aligners, particularly Invisalign, showed benefits like shorter treatment times and higher patient satisfaction. However, variability in treatment accuracy and limited long-term follow-up indicate a need for further research. Overall, clear aligners offer a discreet, flexible, and effective orthodontic option.
