The forces and moments supplied by braces determine the movement of tooth in orthodontic treatment, so clearly quantifying the force value is very important to formulate precise treatment plan. In recent decades, scholars have presented many articles about biomechanical research on orthodontic force. Based on investigations of these papers, techniques on orthodontic force stimulation including oral model (bone, PDL and teeth included) reconstruction and constitute model construction, methods in orthodontic force measurement including physical oral model fabrication and device architectures, and techniques on orthodontic force control such as the use of shape memory alloy and shape memory polymer as the wire material, are reviewed. At the end, the conclusions and future works are given.
