本试验的目的是评估和比较联合骨骼支抗的正畸治疗和使用头盔或横腭杆的传统支抗治疗之间的疼痛、不适和颌骨功能损害。为了开始正畸治疗，连续招募了120名青少年患者，并将其随机分为三组，分别使用不同的支抗。A组植入骨性支抗(OnPLANT或Orthossystem种植体)，B组植入头盔，C组植入横腭杆。使用调查问卷评估从基线到治疗结束的疼痛强度、不适感、止痛剂用量和颌骨功能损害。总体疼痛评分在第2天达到峰值，在第7天几乎恢复到基线。治疗期间疼痛评分最高的部位是接触的门牙，但组间没有差异。在治疗的前4天，骨性支抗A组的磨牙疼痛强度明显低于横腭杆C组，且与头盔相比没有明显差异。结果证实，在正畸治疗期间，患者对骨骼支抗系统和传统支抗系统的认知几乎没有显著差异。因此，这些新矫治器在很长一段时间内都被患者接受，因此可以推荐。
The aim of this trial was to evaluate and compare perceived pain, discomfort, and jaw function impairment between orthodontic treatments combined with skeletal anchorage and treatment using conventional anchorage with headgear or transpalatal bar. A total of 120 adolescent patients in order to start orthodontic treatment were consecutively recruited and randomized into three groups with different anchorage. Group A underwent installation of a skeletal anchorage (Onplant or Orthosystem implant), group B received headgear, and group C a transpalatal bar. Questionnaires were used to assess pain intensity, discomfort, analgesic consumption, and jaw function impairment from baseline to the end of treatment. Pain scores overall peaked on day 2 and were almost back to baseline on day 7. The site with the highest pain scores during treatment was incisors in contact but with no differences between groups. Pain intensity from molars was significantly less in the skeletal anchorage group A compared to the transpalatal bar group C the first 4 days in treatment and with no sign differences compared to headgear. The results confirm that there were very few significant differences between patients' perceptions of skeletal and conventional anchorage systems during orthodontic treatment. Consequently, these new appliances were well accepted by the patients in a long time perspective and can thus be recommended.
