口周肌功能训练配合上牙合垫矫治器在替牙期前牙反牙合治疗中的应用

目的 探究口周肌功能训练配合上牙合垫矫治器在替牙期前牙反牙合矫治中的效果。方法 选取 2020年7月-2021年1月广州市荔湾区口腔医院临床就诊的替牙期前牙反牙合的30例患者为研究对象，随机 分为对照组与观察组，各15例。对照组予以单一上颌牙合垫矫治器治疗，观察组在对照组基础上联合口周 肌功能训练，比较两组矫治时间，以及1年后复发率。结果 观察组矫治时间短于对照组，差异有统计学 意义（P＜0.05）；观察组1年后复发率低于对照组，差异有统计学意义（P＜0.05）。结论 口周肌功能训练 配合上牙合垫矫治器在替牙期前牙反牙合矫治中的疗效确切，能够缩短治疗时间且复发率较低。

Application of Perioral Muscle Function Training Combined with Maxillary Occlusal Pad Appliance in the Treatment of Anterior Crossbite During the Mixed Dentition Stage

Objective To explore the effect of perioral muscle function training combined with maxillary occlusal pad appliance in the treatment of anterior crossbite during the mixed dentition stage. Methods From July 2020 to January 2021, 30 patients with anterior crossbite during the mixed dentition stage in Guangzhou Liwan District Stomatological Hospital were randomly divided into control group and observation group, with 15 patients in each group. The control group was treated with single maxillary pad appliance, and the observation group was treated with perioral muscle function training on the basis of the control group. The treatment time and recurrence rate after 1 year were compared between the two groups. Results The correction time of the observation group was shorter than that of the control group, and the difference was statistically significant (P<0.05). The recurrence rate of the observation group was lower than that of the control group after 1 year, and the difference was statistically significant (P<0.05). Conclusion perioral muscle function training combined with maxillary occlusal pad appliance is effective in the treatment of anterior crossbite during the mixed dentition stage, which can shorten the treatment time and reduce the recurrence rate.
