上唇系带附着异常及其治疗方法研究进展

Research progress of abnormal adhesion of the maxillary labial frenum and its therapies

上唇系带位于面部美学区,将唇、颊黏膜连接到牙槽黏膜、牙龈和骨膜,以便能够适应正常的唇活动。其附着异常与母乳喂养困难、菌斑堆积、儿童龋病、牙周疾病的发生和进展、上颌中切牙间隙等密切相关。因此,及时对异常附着的上唇系带进行治疗至关重要。文章对上唇系带的发育与解剖结构、上唇系带附着异常的临床诊断与分类方法、上唇系带附着异常与上颌中切牙间隙的关系以及上唇系带附着异常的治疗方法等几方面内容做一综述。

The maxillary frenum locates in the facial aesthetic area,which is a mucous membrane fold that attaches the lip and the cheek to the alveolar mucosa,the gingiva,and the underlying periosteum and adapt to the mobility of lip. Its abnormal adhesion is closely related to the breastfeeding difficulties,plaque accumulation,child caries,the development of periodontal disease and maxillary midline diastema. Therefore,it is important to treat abnormal adhesion of maxillary labial frenum timely. This article reviews the development and anatomic structure of maxillary labial frenum,the clinical classification and diagnostic methods of the abnormal adhesion of maxillary libial frenum,the relationship between abnormal adhesion of the maxillary labial frenum and maxillary midline diastema and its therapies.
