Altered passive eruption is described as a condition in which the relationship between teeth, alveolar bone and soft tissues creates an excessive display of gingiva, commonly known as a 'gummy smile'. While there are authors who consider altered passive eruption to be a risk to periodontal health, its impact is greatest in terms of oral esthetics. The aim of periodontal management in such cases is not only to improve patient esthetics but also to restore periodontal health by re-establishing the normal relationship between the gingival margin, alveolar bone crest and cemento-enamel junction. The aim of this article is to present a narrative review of the etiology, classification and management of altered passive eruption.
错颌畸形导致的被动萌出是一种牙齿、牙槽骨和软组织之间的关系导致牙龈过度外露的情况，通常被称为“露龈笑”。虽然有作者认为错颌畸形导致的被动萌出对牙周健康有风险，但它对口腔美观的影响最大。在这种情况下，牙周管理的目的不仅是改善患者的美观，还要通过重新建立牙龈边缘、牙槽嵴顶和牙釉质-牙骨质界之间的正常关系来恢复牙周健康。本文旨在对错颌畸形导致的被动萌出的病因、分类和处理进行综述。
