“…Current research on orthodontic archwire mechanics has focused on FEA, [12][13][14][15][16][17][18] and experimental measurements. [19][20][21][22][23] Although these methods obtain a certain relationship between orthodontic force/torque and archwire deformation. However, no specific quantitative relationship is given.…”

The incidence of oral malocclusion is increasing and is seriously damaging the oral health of human beings. The Kitchon root‐controlled auxiliary archwire is an individualized orthodontic arch. It is used clinically for the treatment of tooth‐lingual tilt/root‐lip tilt phenomenon of the central incisors. However, the bending parameters of the Kitchon root‐controlled auxiliary archwire used in different patients are based on the clinical experience of the dentists. Therefore, this orthodontic treatment has a high risk and unpredictability. In this paper, the loading performance and orthodontic process of Kitchon root‐controlled auxiliary archwire are analyzed. And the prediction model of support resistance and correction torque are established. The bending parameters of the Kitchon root‐controlled auxiliary archwire, as well as the effect of the bending parameters on the support resistance and the correction torque, are all quantified. And the prediction models for the support resistance and the correction torque are calculated separately. The correlation coefficients of calculated data and experimental data are ξT1 > .97 and ξA1 > .96, respectively; the correlation coefficients of simulated data and experimental data are ξT2 > .96 and ξA2 > .96, respectively. The accuracy and reliability of the established prediction models are verified. It provides an effective theoretical guide for dentists to safely and efficiently perform root‐controlled rotation orthodontic treatment on patients' central incisors.

“…Taking the dental plaster model as the research object, the force of teeth under four kinds of hyperelastic archwire and two kinds of invisible orthodontic appliances was analyzed [28]. In 2016, Midorikawa et al designed a set of orthodontic force sensing system, which can measure the stress state of 14 teeth at the same time [29]. In 2017, Higa et al constructed a stress measuring device for small-diameter nickel-titanium alloy wires to measure the force produced by the wires.…”

The abnormal tooth arrangement is one of the most common clinical features of malocclusion which is mainly caused by the tooth root compression malformation. The second sequential loop is mostly used for the adjusting of the abnormal tooth arrangement. Now, the shape devise of orthodontic archwire depends completely on the doctor’s experience and patients’ feedback, this practice is time-consuming, and the treatment effect is unstable. The orthodontic-force of the different parameters of the second sequence loop, including different cross-sectional parameters, material parameters, and characteristic parameters, was compared and simulated for the abnormal condition of root compression deformity. In this paper, the analysis and experimental study on the unidirectional orthodontic-force were carried out. The different parameters of the second sequential loop are analyzed, and the equivalent beam deflection theory is used to analyze the relationship between orthodontic-force and archwire parameters. Based on the structural analysis of the second sequential loop, the device for measuring orthodontic force has been designed. The orthodontic force with different structural characteristics of archwire was compared and was measured. Finally, the correction factor was developed in the unidirectional orthodontic-force forecasting model to eliminate the influence of inherent error. The average relative error rate of the theoretical results of the unidirectional orthodontic-force forecasting model is between 12.6% and 8.75%, which verifies the accuracy of the prediction model.
