Summary

Clear aligner refinements offer limited improvement for deep bite correction. Most overbite correction occurs with the initial aligner set, with subsequent refinements showing minimal additional benefit.

Background:

Refinements are frequently employed in clear aligner treatments.
Assessing predictability in deep overbite correction is crucial for treatment success.

Purpose of the Study:

To evaluate the predictability of deep overbite correction across multiple clear aligner refinements.
To examine the accuracy of vertical tooth movement and inclination changes during clear aligner therapy.

Main Methods:

Retrospective analysis of 20 deep bite patients treated with clear aligners (Invisalign).
Comparison of initial, predicted, and achieved dental models using surface-based registration.
Measurement of overbite correction, vertical movements, and tooth inclination changes.

Main Results:

Mean overbite correction accuracy was 37.63% after the first aligner set, decreasing in subsequent refinements.
Statistically significant differences were observed between predicted and achieved vertical movements and inclinations for most teeth.
Completed treatments showed mean overbite correction of 38.54%, similar to the first set's outcome.

Conclusions:

The majority of deep bite correction is achieved with the initial set of clear aligners.
Refinement stages in clear aligner treatment do not significantly enhance deep bite correction outcomes.
