During orthodontic treatment, irregular and varying sized nodular bony protrusions may sometimes appear on the labial side of the patient's anterior alveolar bone, which is closely related to the differential bone remodeling on the inner and outer surfaces of the alveolar bone. Labial protuberances not only affect the aesthetic results of orthodontic treatment, but also pose potential risks to periodontal health. Currently, it is believed that the influencing factors of the formation of the labial protuberances may be related to the patient's gender and age, tooth movement speed, and extent of anterior teeth retraction. Labial protuberances typically resolve spontaneously, however, if persistent, alveoloplasty may be necessary for treatment. This review provides a summary on the occurrence, influencing factors of formation, potential biological mechanisms, and corresponding treatment methods of labial protuberances during orthodontic treatment.
在正畸治疗过程中，患者前牙槽骨唇侧有时会出现不规则且大小不一的结节状骨质突出，这与牙槽骨内外表面的差异性骨重塑密切相关。唇侧突出不仅影响正畸治疗的美学效果，还对牙周健康构成潜在风险。目前认为，唇侧突出形成的影响因素可能与患者的性别、年龄、牙齿移动速度以及前牙内收程度有关。唇侧突出通常会自行消退，然而，如果持续存在，则可能需要进行牙槽成形术来治疗。本文综述了正畸治疗过程中唇侧突出的发生情况、形成的影响因素、潜在生物学机制及相应的治疗方法。
