Abstract
Orthodontic treatment utilizes the biomechanical adaptive deformation of alveolar bone in response to external forces. The alveolar bone resorption rate is one of the fundamental factors for describing a remodeling process of the hard tissue. This paper describes a new estimation technique for the resorption rate during orthodontic treatment. We estimated the amount of alveolar bone resorption from clinical measurements of 3-D tooth movement during the treatment. We also calculated the stress around the tooth root with 3-D finite-element analysis. These values were obtained under the various conditions of clinical treatments. The rate to a unit stress obtained from the maxillary canine of patients was found to be 0. 6 ± 0. 2 μm/ (kPa. day) .
