Complete orthodontic load systems on teeth in a continuous full archwire: the role of triangular loop position.

Introduction: A novel approach to characterizing orthodontic spring-generated force and moment systems has been developed. This method allows simultaneous measurement of all 6 force and moment components acting on a tooth.

Methods: A continuous full archwire space-closure technique was simulated, and the complete force and moment systems acting on the teeth adjacent to the extraction space were measured.
