A mathematical approach to bone tissue engineering.

چکیده
Tissue engineering is becoming consolidated in the biomedical field as one of the most promising strategies in tissue repair and regenerative medicine. Within this discipline, bone tissue engineering involves the use of cell-loaded porous biomaterials, i.e. bioscaffolds, to promote bone tissue regeneration in bone defects or diseases such as osteoporosis, although it has not yet been incorporated into daily clinical practice. The overall success of a particular bone tissue engineering application depends strongly on scaffold design parameters, which do away with long and expensive clinical protocols. Computer simulation is a useful tool that may reduce animal experiments and help to identify optimal patient-specific designs after concise model validation. In this paper, we present a novel mathematical approach to bone regeneration within scaffolds, based on a multiscale framework. Results are presented over an actual scaffold microstructure, showing the potential of computer simulation, and how it can aid in the task of making bone tissue engineering a reality in clinical practice.

A Mathematical Approach for Describing Time-Dependent Poisson’s Ratios of Periodontal Ligaments
Periodontal ligament is a thin layer of soft tissue that connects root of a tooth to the surrounding alveolar bone. These ligaments play an important role in initiating tooth movement when loads are applied to teeth with orthodontic appliances. The majority of such soft tissues exhibit as viscoelastic bodies or have a time-dependent behavior. Due to the viscoelastic behavior of the periodontal ...
متن کاملA Review on Commonly Used Scaffolds in Tissue Engineering for Bone Tissue Regeneration
Introduction: Bone is one of the tissues that have a true potential for regeneration. However, sometimes the bone defects are so outsized that there is no chance of bone self-repair and restoration or the damage is such that it is not possible to repair with medical or surgical interventions. In these situations, bone grafts are the treatment of choice, but due to several obstacles, including l...
