The strength of lining materials under constraint

C H Lloyd, I W Jeffrey, M J Mannion

    Journal of Oral Rehabilitation
    |September 1, 1982
    PubMed
    Summary

    Peripheral constraints significantly enhance the compressive strength of Dycal lining material. This finding allows for increased confidence in using Dycal in applications with external support and confinement.

    Area of Science:

    • Materials Science
    • Biomaterials Engineering

    Background:

    • Dycal is a dental lining material known for its calcium hydroxide composition.
    • Its low compressive strength has historically limited its applications.
    • Understanding material behavior under stress is crucial for clinical success.

    Purpose of the Study:

    • To investigate the effect of peripheral constraints on the compressive strength of Dycal.
    • To determine if external support can improve the mechanical performance of Dycal.
    • To assess the applicability of the Von Mises yield criterion to constrained Dycal.

    Main Methods:

    • Applying varying degrees of peripheral constraint to Dycal samples during compressive testing.
    • Measuring the stress required to induce fracture under constrained conditions.
    • Analyzing the summed stresses using the Von Mises yield criterion.

    Main Results:

    • Compressive strength of Dycal increased with the application of peripheral constraints.
    • The fracture stress directly correlated with the degree of constraint applied.
    • The Von Mises yield criterion effectively characterized the strength under constraint.

    Conclusions:

    • External support and confinement can significantly improve the compressive strength of Dycal.
    • Materials with previously limited compressive strength can be utilized more reliably with adequate external support.
    • This research broadens the potential applications for Dycal in restorative dentistry and other fields.
