Reliability of different composite materials in aligner treatments: a comprehensıve in vitro study

Material viscosity and filler content substantially influence clinical performance during extended treatments. GC Aligner Connect demonstrated optimal balance of placement efficiency, dimensional accuracy, and durability for routine applications. High-viscosity composites showed superior long-term stability despite longer placement times. Injectable composites offered excellent efficiency but demonstrated accelerated wear after 48 weeks. These findings provide evidence-based guidance for material selection in clear aligner therapy, suggesting material choice should align with anticipated treatment duration and clinical requirements.
