Effects of refinement procedures on enamel surface integrity in clear aligner therapy: a 3D micro-CT study

Key Points

To investigate how refinement procedures affect the enamel surface during clear aligner therapy.
Conducted a 3D micro-CT analysis to assess enamel surface integrity.
Examined the cumulative effects of repeated attachment debonding.
Evaluated tissue loss after multiple debonding applications.
Enamel surface integrity was significantly compromised after repeated attachment debonding.
Tissue loss became more pronounced after the second debonding procedure.

Abstract

The cumulative effect of repeated attachment debonding is significant, with tissue loss becoming more pronounced after the second application. The need for refinement should be carefully evaluated.
