Consistent with his clinical education in orthodontics, Dr. Taylor is keenly interested in the organization and development of the extracellular matrix (ECM) of craniofacial structures, specifically, the periodontal ligament (PDL). He hopes to gain additional insight into the biological processes that when activated by a sustained force applied to a tooth results in orthodontic tooth movement. He also hopes to determine if there are different mechanisms related to the magnitude of the applied force, and if so, begin to tease out these magnitude-determined differences. This will, ultimately, help us as orthodontists utilize the most biologically efficient force systems for orthodontic tooth movement.
