正畸治疗是否可以改变首选咀嚼侧（PCS）是未知的。本研究探讨（1）正畸治疗后PCS是否发生变化，以及（2）哪些因素导致了这种变化。该研究纳入了2017年至2020年间在东京医科齿科大学医院正畸诊所就诊的250名患者。治疗前后分别测量下颌运动描记器（MKG）和PCS。将治疗后PCS显示对侧变化的患者和PCS未显示变化的患者分别合并至PCS变化组和PCS不变组。比较两组的人口统计学、临床和头影测量参数。与正畸治疗开始时年龄< 20岁（OR = 2.00）、治疗前最大下颌侧向移动至PCS ≥ 10.0 mm（OR = 6.51）和咬合倾斜变化≥1.0°（OR = 2.72）相关的显著因素。无因素、单因素和双因素与PCS变化相关时，PCS变化的预测概率分别为13.2%、36.0%和67.5%。正畸治疗可能会改变PCS由于患者的年龄，最大的侧向下颌运动PCS，并在咬合倾斜的变化。
Whether orthodontic treatment can change the preferred chewing side (PCS) is unknown. This study examined (1) if the PCS changes after orthodontic treatment and (2) which factors contribute to this change. Two hundred fifty patients who visited the orthodontic clinic at Tokyo Medical and Dental University Hospital between 2017 and 2020 were included in the study. Mandibular kinesiograph (MKG) was taken at pre- and post-treatment, and PCS was determined. Patients who showed a change in PCS to the opposite side and those who showed no change in PCS at post-treatment were pooled into the PCS-changed and PCS-unchanged groups, respectively. The demographic, clinical, and cephalometric parameters were compared between the groups. Significant factors associated with changes in were of age < 20 years at the beginning of orthodontic treatment (odds ratio (OR), 2.00), maximum lateral mandibular movement to PCS ≥ 10.0 mm at pre-treatment (OR, 6.51), and change in occlusal canting of ≥1.0° (OR, 2.72). The predicted probability of change in PCS was 13.2%, 36.0%, and 67.5% for no factor, one factor, and two factors associated with PCS change, respectively. Orthodontic treatment may change PCS due to patient age, maximum lateral mandibular movement to PCS, and change in occlusal canting.
