Background:
To explore the effects of a combined orthodontic and restorative approach on chewing, swallowing, and language function in patients with malocclusion and dental defects.
Methods:
A total of 112 patients with malocclusion and dentition defects admitted to the Lianyungang Hospital of Traditional Chinese Medicine from June 2019 to June 2022 were prospectively selected. The patients were divided into study and control groups using a simple random number table method, with 56 patients in each group. The control group received routine restoration, whereas the study group received a combination of orthodontic and restorative treatments. The chewing function, swallowing and language function, and gingival periodontal condition before and after treatment in both groups were compared using t-test or Wilcoxon test, while treatment satisfaction were compared using chi-square test or Fisher exact test.
Results:
After treatment, maximum area frame bite force/max movie force in both groups increased compared to before treatment, while occlusion time, bite force distrbution balance, and standard deviation hue decreased compared to before treatment. Moreover, maximum area frame bite force/max movie force in the study group was higher than that in the control group, whereas occlusion time, bite force distrbution balance, and standard deviation hue were lower than those in the control group (P < .05). The swallowing and language function scores of the study group were higher than those of the control group (P < .05). After treatment, the bleeding index, plaque index, and probing depth of both groups decreased compared to before treatment, and the study group was lower than the control group (P < .05). The treatment satisfaction of the study group (94.64%) was higher than that of the control group (82.14%) (P < .05).
Conclusion:
Adopting a combined orthodontic and restorative approach to intervene in patients with malocclusion and dentition defects is beneficial for improving their periodontal condition, effectively restoring chewing, swallowing, and language functions, and achieving high patient satisfaction.
