Purpose: The presentation of a simple method of evaluation of the effectiveness to relieve the mucous membrane under thednture through soft lining materials, which is based on the analysis of creep curves and energy dissipated by the samples during the cyclic compression. Design/methodology/approach: On the testing machine there were conducted studies of time characteristics and there was determined the energy dissipated by the samples during the cyclic compression. The results were subjected to the analysis of variation ANOVA (α=0.05) with the Newman-Keuls post-hoc test. Findings: The presented method allowed to conduct the evaluation of abilities to relieve the mucous membrane of soft lining materials significantly different in hardness. The studies showed that the softer materials characterised with a greater ability to dissipate energy, nevertheless, after taking the load off, the return to the original form in case of materials with the lowest hardness lasted much longer. The samples of softer materials with large values of stress underwent much greater stiffening, Research limitations/implications: Limitations not allow the full translation of the obtained results into the expected results of clinical trials. The demonstrated relations between the behaviour of the samples and the hardness of materials are proper for the tested materials, but not necessarily for other materials of a similar hardness. Practical implications: The presented methodology of the research is even closer to the expected clinical reality, when the alveolar ridge is more uniform and flat, but in order to obtain an even fuller image of the situation in case of uneven or sharp alveolar ridges, one should conduct additional tests with the method consisting of the load of the samples with a properly shaped penetrator. Originality/value: The advantages of the presented methods are: the possibility for a quantitative use of the comparison of energy dissipated by the samples and the estimation of the material reaction while maintaining the possibility to use the tests of variable values of stresses, what enables an easy association of the obtained results with the values of stresses, which cause pain sensations in the mucous.
