    Summary
    This summary is machine-generated.

    This study investigated the creep rate in dental amalgam restorations. High loads can cause gaps between the restoration and tooth margins due to amalgam

    Area of Science:

    • Dental materials science
    • Biomaterials engineering
    • Mechanical dentistry

    Background:

    • Dental amalgam restorations are widely used.
    • Understanding material behavior under load is crucial for longevity.
    • Class V restorations are susceptible to specific stress patterns.

    Purpose of the Study:

    • To analyze the creep rate of amalgam Class V restorations.
    • To quantify the relationship between stress and deformation in dental fillings.
    • To predict potential restoration failure modes.

    Main Methods:

    • Utilized the finite element method to compute stresses.
    • Calculated creep rate based on determined stress values.
    • Simulated loading conditions on a bicuspid tooth model.

    Main Results:

    • Creep rate varied from 0.6% to 3.5% per 104 s under a 150 N load.
    • Significant differences in viscoelastic behavior influenced creep rates.
    • Predicted gap formation between restoration and cavity margins under heavy, frequent loading.

    Conclusions:

    • Dental amalgam restorations can exhibit significant creep.
    • Material viscoelasticity plays a key role in restoration performance.
    • Heavy occlusal loading may compromise the integrity of Class V amalgam restorations, leading to marginal gap formation.
