[A theoretical study of bite opening with Begg technique].
The authors made a thorough and careful study on the Begg Stage I appliance and established a model of mechanics in accordance with the actual situation of arch wire being activated and derived a mathematical formula based on the elastic small deflection theory. This study provides not only the basis of choosing intrusive-force value for individual arches, but also the possibility of analysing dynamically the changes of intrusive- force value in the process of bite opening.
