Evaluation of effects of different sizes and shapes of attachments during rotation, tipping, and torquing in clear aligner therapy – A finite element study

The size and geometry of composite attachments were shown to be extremely important in regulating tooth movement during clear aligner treatment, according to this FEA research. Greater displacement is produced when smaller attachments with less surface area dissipate more force. When using clear aligner therapy, orthodontists may optimize treatment plans, shorten treatment times, and provide more predictable results by having a better understanding of the biomechanics of various attachment designs.
