OBJECTIVES: This study evaluated the influence of different rehydration media and time periods on biomechanical and structural properties of different acellular collagen matrices (ACMs). MATERIALS AND METHODS: Specimens of three ACMs (mucoderm®, Mucograft®, Dynamatrix®) were rehydrated in saline solution (SS) or human blood for different time periods (5-60 min). ACMs under dry condition served as controls. Biomechanical properties of the ACMs after different rehydration periods were determined by means of tensile testing. ACMs' properties were further characterized using Fourier-transform-infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). RESULTS: At dry conditions, mucoderm® presented the highest tensile strength (TS) and Dynamatrix® showed the maximum elastic modulus (EM; p each ≤0.036). Rehydration in SS and blood resulted in significant TS changes of mucoderm® (p each ≤0.05). Concering EM, mucograft® showed significantly decreased values after rehydration in SS compared to Dynamatrix® and mucoderm® after 10 min (p each ≤0.024). mucoderm® hydrated for 5 min in blood displayed nearly double TS and a significantly increased EM after 60 min (p = 0.043) compared to rehydration in SS. TS and EM values of Dynamatrix® and Mucograft® were not altered following rehydration in blood versus SS (p each ≥0.053). FTIR analysis confirmed the recovery of the graft protein backbone with increased rehydration in all samples. DSC measurements revealed that tissue hydration decreased thermal stability of the investigated ACMs. CONCLUSION: Our findings demonstrated that the rehydration protocol affects the biomechanical properties of ACMs. CLINICAL RELEVANCE: Clinicians should be aware of altered handling and mechanical properties of ACMs following different rehydration protocols.
