Objective assessment of daily wear time of removable appliances is possible, so the next step is to ascertain whether the severity of malocclusion influences patients' compliance. This could help resolve the controversy over the question of whether removable appliance therapy truly works.
The aim of the study was to investigate whether the patient's orthodontic treatment needs affect the cooperation between the patient and the doctor, and to find a correlation that could affect recommendations for orthodontic treatment.
The study involved 58 patients (29 boys, 29 girls) aged 9-12 years, who qualified for treatment with removable appliances equipped with a sensor system. The patients were divided into four groups according to their Index of Orthodontic Treatment Need dental health component scores. Over a 9-month period, data stored in the sensors were compared with the recommended daily wear time (DWT) of the appliances, and a statistical analysis was conducted.
DWT differed considerably in all the groups. Statistically significant differences in the mean DWT values occurred only when extreme values of the IOTN DHC were compared.
The degree of patient compliance depends to a small extent on the severity of malocclusion. Patients with mild malocclusion will probably be less likely to cooperate. Among patients with severe malocclusion, compliance may be unpredictable. Patient compliance is an important background factor that can explain a lot of the controversy over the effectiveness of treatment with removable appliances.
客观评估可摘矫治器的每日佩戴时间是可行的，因此下一步是确定错颌畸形的严重程度是否会影响患者的依从性。这有助于解决关于可摘矫治器治疗是否真正有效的争议。
本研究的目的是调查患者的正畸治疗需求是否会影响患者与医生之间的合作，并找到一种可能影响正畸治疗建议的相关性。
该研究纳入了58名年龄在9至12岁之间的患者（29名男孩，29名女孩），他们符合使用配备传感器系统的可摘矫治器进行治疗的条件。根据正畸治疗需求指数的口腔健康成分得分，将患者分为四组。在9个月的时间里，将传感器中存储的数据与矫治器的推荐每日佩戴时间（DWT）进行比较，并进行统计分析。
所有组的DWT差异很大。仅在比较IOTN DHC的极端值时，平均DWT值才出现统计学上的显著差异。
患者的依从程度在一定程度上取决于错颌畸形的严重程度。轻度错颌畸形的患者可能不太愿意合作。在严重错颌畸形的患者中，依从性可能无法预测。患者依从性是一个重要的背景因素，可以解释很多关于可摘矫治器治疗效果的争议。
