Clear aligner attachment accuracy and composite excess using flowable composite resins of varying viscosities

Key Points

• The study examines how composite viscosity and attachment design affect accuracy and excess in clear aligner treatments.
• Comparison of high-viscosity and low-viscosity resins
• Assessment of attachment accuracy
• Measurement of composite excess
• High-viscosity resins improve attachment accuracy but increase excess
• Low-viscosity resins reduce excess but may compromise accuracy
• Material choice influences clinical decision-making in clear aligner treatments
