Background: Malocclusion is one of the three major oral diseases which affect the quality of
human life and mental health. The fixed appliance technology is most commonly used to treat malocclusion.
Nowadays, the designs of orthodontic appliances mostly rely on doctors’ experience. It is significant
to study orthodontic forces to improve the effectiveness of orthodontic treatment and alleviate
the sufferings of the patients. The orthodontic force measurement is the fundamental of the research on
the orthodontic forces.
Objective: This paper attempts to present a general summarization of recent studies about orthodontic
force measuring devices and introduce their respective characteristics and development including their
components and experimental steps.
Methods: This paper reviews various representative studies related to the orthodontic force measuring
devices. The research topics discussed the components of recent orthodontic force measuring devices,
experimental steps, experimental materials, applications and the characteristic of the presented orthodontic
force measuring devices.
Results: The advantages and disadvantages of different types of the orthodontic force measuring devices
are discussed, and the structural characteristics are concluded. In addition, the main problems in
its development are analyzed, the solutions to the issues and the current and future research on
orthodontic force measuring device are discussed.
Conclusion: Orthodontic force measuring device plays an important role in the orthodontic measurement.
The orthodontic force measurement result can help orthodontic doctors improve the effectiveness
of the orthodontic treatment. And further improvements are needed in the aspects of experimental dentition
model built by biomimetic materials, the rebuilt of the real biological environment of human mouth
and portability of the orthodontic force measuring devices. More studies on the orthodontic force measuring
device should be conducted.
