Tristar Comparison

Many aligner companies, and dental clinics are using single or dual layered materials in order to perform treatment on their patients.

This is why there is significant lag – between the design of the aligner stage and actual clinical performance intraorally.

The new paradigm involves combining sheet materials – different layers that provide a strong, impact-resistant outer shell, but a soft, elastomeric inner layer. This maximises patient comfort yet ensures consistent force delivered throughout the current aligner stage. This minimizes aligner lag and maximises aligner results.
