The aim of this paper is to elucidate a new method for quantitatively evaluating orthodontic force system during orthodontic treatment. Dental cast models were made to obtain digital models with impressions of a patient´s dental arch at regular intervals. Then the displacement of each bracket for a period of time was obtained by computer aided inspection. The finite element model of archwire in free status and brackets engaged in archwire was built. With the derived displacements applied as boundary condition, the orthodontic force system at a random time was derived by a finite element analysis. This method can quantitatively evaluate the spatial orthodontic force system at an arbitrary time during orthodontic treatment, thus provide the clinical treatment and theoretical study with important information.
