  • dynamic Shear behavior of mandibular condylar cartilage is dependent on testing direction

    Abstract:

    Little information is available on the direction-dependency of Shear behavior in mandibular condylar cartilage. Therefore, we tested the hypothesis that such a dependency of the dynamic Shear properties is present in mandibular condylar cartilage. From each of 17 condyles, two cartilage-bone plugs were dissected and tested in a simple Shear sandwich configuration under a compressive Strain of 10%. Sinusoidal Shear Strain (frequency range: 0.01-10 Hz) was applied in the medio-lateral or antero-posterior direction with an amplitude of 1.0%, 2.0%, and 3.0%. The magnitudes of the dynamic Shear moduli, as calculated from the resulting Shear stress, were found to increase with applied frequency and the Shear Strain amplitude. The values |G*|, G' and G'' for a medio-laterally applied Shear were about 20-33% of those in the antero-posterior Shear, although the loss tangent (elasticity/viscosity ratio) was almost the same. In conclusion, the present results clearly show the direction-dependent characteristic of the mandibular condylar cartilage in dynamic Shear.

    Abstract:

    Shear stress can result in fatigue, damage, and irreversible deformation of the mandibular condylar cartilage. However, little information is available on its dynamic properties in Shear. We tested the hypothesis that the dynamic Shear properties of the condylar cartilage depend on the frequency and amplitude of Shear Strain. Ten porcine mandibular condyles were used for dynamic Shear tests. Two cartilage-bone plugs were dissected from each condyle and tested in a simple Shear sandwich configuration under a compressive Strain of 10%. Sinusoidal Shear Strain was applied with an amplitude of 1.0, 2.0, and 3.0% and a frequency range between 0.01 and 10 Hz. The magnitudes of the Shear dynamic moduli were found to be dependent on the frequency and the Shear Strain amplitude. They increased with Shear Strain. tan delta ranged from 0.2 to 0.4, which means that the cartilage is primarily elastic in nature and has a small but not negligible viscosity. In conclusion, the present results show that the Shear behavior of the mandibular condylar cartilage is dependent on the frequency and amplitude of the applied Shear Strain. The observed Shear characteristics suggest a significant role of Shear Strain on the interstitial fluid flow within the cartilage
