    Zinc phosphate cement creates the highest intracoronal pressure during crown cementation, while zinc oxide-eugenol cement generates the least. This pressure may not significantly hinder complete crown seating.

    Area of Science:

    • Dental Materials Science
    • Biomaterials Engineering

    Background:

    • Accurate crown seating is crucial for long-term restoration success.
    • Understanding intracoronal pressure during cementation is vital for material selection.

    Purpose of the Study:

    • To develop a model system for measuring intracoronal pressure during dental crown cementation.
    • To compare the peak and residual pressures generated by different dental cements.

    Main Methods:

    • A novel model system was employed to simultaneously record intracoronal pressure at three distinct locations.
    • The system was used to evaluate pressure dynamics during the cementation of dental crowns using various luting agents.

    Main Results:

    • Zinc phosphate cement exhibited the highest peak and residual intracoronal pressures.

    Related Experiment Videos

  • Zinc oxide-eugenol cement generated the lowest peak and residual pressures.
  • Polycarboxylate cement demonstrated intermediate pressure levels.

    • Conclusions:

    • Intracoronal pressure varies significantly among different dental cements.
    • The observed pressure patterns suggest complex cement flow dynamics.
    • Low residual pressures indicate a limited role in preventing complete crown seating.
