Collagen fibers of the Periodontal ligament (PDL) play a crucial role in determining its mechanical properties. Based on this premise, we investigated effect volume fraction human PDL collagen hyperelastic behavior under transient loading. Samples were obtained from different root regions (neck, middle, and apex) PDL, prepared fresh anterior teeth. The various was quantified by staining techniques combined with image processing software. fiber fractions found to be 60.3% neck region, 63.1% middle 52.0% apex region. A new constitutive model constructed based fraction. uniaxial tensile test conducted these samples, accuracy validated fitting data. Also, relevant parameters derived. results demonstrated that exhibited properties condition With an increase fibers, resistance enhanced, demonstrating more significant showed good fit experimental (R2 > 0.997), describing effectively.
