Biomechanical finite-element investigation of the applicability of the orthodontic concept of the center of resistance

Orthodontic tooth movement is achieved by application of forces to teeth. The objective of this study was to estimate applicability of the concept of the center of resistance and to offer more accurate method to describe the process of initial movements of teeth. A three-dimensional finite-element model of a lower human mandible was developed on the basis of computer tomography image data.
