Summary

This prospective clinical study evaluated the incidence of composite attachment loss in patients undergoing clear aligner treatment and identified patient-, tooth-, and treatment-related factors associated with attachment debonding. Twenty-one patients were followed for six months, and attachment failures were recorded at routine visits. Outcomes were compared according to attachment type (conventional vs. optimized), attachment size, tooth type, dental arch, and patient-related factors.

Conditions

  • Malocclusion
  • Crowded Teeth
  • Attachment

Interventions

DEVICE

Clear Aligners with Composite Attachments

Participants received clear aligner therapy (Invisalign®, Align Technology, San Jose, CA, USA). Composite attachments were bonded according to the manufacturer's protocol using a high-viscosity composite. Both conventional and optimized attachment types were used as part of the planned orthodontic treatment, and attachment loss was prospectively evaluated during a 6-month follow-up period.
