Oral habits, such as mouth breathing, sucking, and lip and tongue habits, are important factors that lead to malocclusion. The abnormal pressure will disrupt the muscle balance of the oral and maxillofacial complex and interfere with the normal development of the maxillofacial complex. Therefore, early diagnosis and successful treatment of oral habits are pivotal to the early treatment of malocclusion. This paper discusses the malocclusion caused by children's oral habits and the corresponding intervention methods.
口腔不良习惯如口呼吸习惯、吮咬习惯、唇习惯、舌习惯等是导致错（牙合）畸形发生发展的重要因素，其产生的异常压力可破坏口颌系统肌力平衡，干扰颌面部正常发育。因此，早期发现并破除口腔不良习惯是错（牙合）畸形早期矫治的关键。本文针对儿童口腔不良习惯所导致的错（牙合）类型及相应的干预手段进行讨论，以期为临床提供参考。.
