Incremental filling techniques for dental composites may increase tooth deformation and stress, contrary to common assumptions. While beneficial for other aspects of restoration, their effectiveness in reducing polymerization shrinkage effects remains unproven.

Area of Science:

  • Biomaterials Science
  • Dental Materials
  • Restorative Dentistry

Background:

  • Polymerization of dental composites causes volumetric contraction and stress.
  • This shrinkage can lead to inward deformation of cavity walls.
  • The assumption that incremental filling reduces shrinkage stress is widely discussed.

Purpose of the Study:

  • To investigate the effect of incremental filling techniques on stress transfer and tooth deformation.
  • To analyze the validity of incrementalization for mitigating polymerization shrinkage effects.
  • To evaluate the sufficiency of intercuspal distance measurements for characterizing shrinkage stress.

Main Methods:

  • Numerical analysis simulating stress fields for various incremental filling techniques.

  • Modeling of tooth-composite interaction with a focus on wall deformation.
  • Comparison of incremental vs. single increment filling effects.

    • Main Results:

    • Incremental filling techniques, with a strong bond to the tooth, increase tooth deformation.
    • This increased deformation results from incremental preparation changes, reducing overall composite volume.
    • The tooth-composite structure becomes more highly stressed.
    • Intercuspal distance measurements and generalized shrinkage stress models are insufficient for comprehensive assessment.

    Conclusions:

    • Incremental filling techniques may paradoxically increase stress and deformation in bonded restorations.
    • While valuable for densification, cure, and bonding, their role in reducing shrinkage effects is questionable.
    • Further research is needed to definitively prove the abatement of shrinkage effects through incrementalization.
