Modeling the Mechanical Behavior of the Periodontal Ligament in Response to Externally Applied Loading

In 2012, the Canadian Institute for Health Information estimated that over $11 billion dollars was spent by Canadians on dental care, with this number projected to rise. One primary area of importance to dentistry is the periodontal ligament (PDL), connective tissue joining the tooth to the surrounding alveolar bone. The PDL plays a critical role in tooth support, distributing applied loads, and facilitating tooth movement during orthodontic treatment. As a result, having a complete understanding of PDL response to applied loading is vital to the field of dentistry. The objective of this program is to investigate the viscoelastic behavior of the PDL and further our understanding of how it effects load distribution in the tooth-PDL-bone complex (TPBC).
