Effects of fixed appliance combined with muscle function exercise on occlusal function and oral health in patients with Class Ⅱ malformations
Objective To explore the effects of fixed appliance and muscle function exercise on oral health and occlusal function in patients with class Ⅱ malformations.Methods From October 2022 to October 2022,92 patients with class Ⅱ malformations were 2023 in our department of Stomatology,the oral health,occlusal function and the improvement of hard/soft tissue were compared before and after treatment.Results:the occlusal function of MMCOF,AOF and COF were significantly decreased after treatment(P<0.05)TOF(total finger force)was significantly increased after treatment(P<0.05).After treatment,the patients'oral functions such as oral esthetics,masticatory function,comfort and fixation were significantly better than those before treatment(P<0.05).Compared with before treatment,the ANB angle,SNA angle,UI-NA angle,OB angle and OJ angle were significantly decreased after treatment(P<0.05)However,the levels of LI-NB,LI-MP and SNB were significantly increased(P<0.05).Conclusion:the combined treatment of fixed appliance and muscle function exercise can obviously improve the occlusal function and hard tissue of patients with class Ⅱ malformations,and has a positive effect on their oral health.
