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.
