儿童正畸治疗中早期功能矫治措施对面型变化与牙列排列的影响

探讨早期功能矫治应用于儿童正畸治疗中的效果及对面型变化、牙列排列的影响。方法 选 择2022年2月-2023年5月黄骅市中医医院口腔科接受正畸治疗的儿童58例，以随机数字表法将其分为 常规组和试验组，各29例。常规组应用无肌功能训练矫治，试验组在常规组基础上增加早期功能矫 治，比较两组治疗效果、面型变化和牙列排列状况、治疗效果满意率。结果 试验组治疗总有效率为 96.55%，高于常规组的82.76%（P＜0.05）；试验组治疗后上中牙的凹距、倾角、SNA角、SNB角、 ANB角、LI-NB角、UI-NA角、NP-FH角、ANS-Me高度优于常规组（P ＜0.05）；试验组治疗效果 满意率高于常规组（P＜0.05）。结论 儿童正畸治疗期间予以早期功能矫治的效果良好，能够有效调整儿 童面型与牙列排列状况，且患者及其家属对治疗满意度较高。

Effect of Early Functional Correction in Orthodontic Treatment of Children and its Effect on Facial Shape Change and Dentition Arrangement

To investigate the effect of early functional correction on orthodontic treatment in children and its effect on facial shape change and dentition arrangement. Methods A total of 58 children who received orthodontic treatment in Department of Stomatology, Huanghua Hospital of Traditional Chinese Medicine from February 2022 to May 2023 were selected and divided into conventional group and experimental group by random number table method, with 29 children in each group. The conventional group was treated with non-muscle function training, and the experimental group was treated with early functional correction on the basis of the conventional group. The treatment effect, facial changes and dentition arrangement, and treatment effect satisfaction were compared between the two groups. Results The total effective rate of treatment in the experimental group was 96.55%, which was higher than 82.76% in the conventional group (P <0.05). After treatment, the concave distance, inclination angle, SNA angle, SNB angle, ANB angle, LI-NB angle, UI-NA angle, NP-FH angle and ANS-Me height of upper and middle teeth in the experimental group were better than those in the conventional group (P <0.05). The satisfaction rate of treatment effect in the experimental group was higher than that in the conventional group (P <0.05). Conclusion The effect of early functional correction during orthodontic treatment in children is good, which can effectively adjust the facial shape and dentition arrangement of children, and the patients and their families are more satisfied with the treatment
