Abstract：Objective The aim of the study was to evaluate the effect of removable appliances used over a 12-month period on growth changes in children with narrowed jaw dimensions. Method 102 patients admitted to Handan Central Hospital from January 2017 to December 2023 were included in the study. These patients were randomly divided into two groups using a random number table method:treatment group (treated with removable appliances) and control group (with-out craniofacial deformities requiring orthodontic treatment). The treatment period was 12 months. The changes in maxillary dental arch width before and after treatment were measured,and SPSS was used for statistical analysis. Result There were no significant differences in gender,age,and height between the two groups. The anterior and posterior width of the maxillary dental arch in the treatment group increased significantly after treatment (P<0.001),and the difference in the rate of increase compared to the control was significant (P=0.01). Conclusion The removable appliance significantly im-proved the problem of narrow maxillary size and had good clinical application value. Early intervention not only corrected tooth alignment and bite,but also improved overall oral function and health.
