Chitosan-Based Biomaterials for Tissue Repair and Regeneration
Tissue repair and regeneration is an interdisciplinary field focusing on development of biological and bioactive substitutes. Chitosan is a natural polysaccharide exhibiting excellent biocompatibility, biodegradability, affinity to biomolecules, and wound-healing activity. It can also be easily modified via chemical and physical reactions to obtain derivatives of various structures, properties,...
متن کاملNanoengineered biomaterials for repair and regeneration of orthopedic tissue interfaces.
UNLABELLED Orthopedic interface tissue engineering aims to mimic the structure and function of soft-to-hard tissue junctions, particularly bone-ligament, bone-tendon, and bone-cartilage interfaces. A range of engineering approaches has been proposed to mimic the gradient architecture, physical properties and chemical characteristics of interface tissues using conventional polymeric biomaterials...
متن کاملBiomaterials for orbital fractures repair
The unique and complex anatomy of the orbit requires significant contouring of the implants to restore the proper anatomy. Fractures of the orbital region have an incidence of 10-25% from the total facial fractures and the most common age group was the third decade of life. The majority of cases required reconstruction of the orbital floor to support the globe position and restore the shape of ...
متن کاملAcellular vascular tissues: natural biomaterials for tissue repair and tissue engineering.
Various research groups around the world are actively investigating cardiovascular prostheses of biological origin. This review article discusses the need for such bioprosthetics and the potential role for natural tissues in cardiovascular applications such as cardiac valves and vascular grafts. Upon implantation, unmodified natural materials are subject to chemical and enzymatic degradation, s...
متن کاملBiomaterials for Periodontal Tissue Regeneration
Periodontal diseases are characterized by alveolar bone absorption and destruction of periodontal ligament and cementum and are the main causes of tooth loss in adults. This series of diseases is harmful to both human oral and body health. Although periodontitis is under control because of the implementation of conventional treatment modalities, regenerating damaged periodontal tissues remains ...
