ABSTRACT
<p><b>OBJECTIVE</b>The purpose of this study was to qualitatively and quantitatively analyze the initial force system of "rocking-chair archwire" on every tooth.</p><p><b>METHODS</b>Three-dimensional finite element model of "rocking-chair archwire" was set up, and nonlinear method was used to analyze the force system.</p><p><b>RESULTS</b>The archwire exerted intruding force, labial force, lingual-root torque and mesial-labial moment on incisors; Extruding force, lingual-root torque and mesial-labial moment were applied on canines and premolars; The archwire also created intruding force, buccal force, buccal-root torque and mesial-labial moment on molars.</p><p><b>CONCLUSIONS</b>"rocking-chair archwire" produced a complicated force system. While intruding incisors, molars and extruding premolars. It has a tendency to induce tooth rotation and tipping.</p>
