ABSTRACT

Orthodontic treatment is a commonly utilized method for improving both facial aesthetics and occlusal function. During orthodontic treatment irregular, nodular labial protuberances on the labial side of the anterior teeth may occasionally occur, varying in number and size, which is closely connected to the differential bone remodeling patterns on the internal and external surfaces of the labial alveolar bone. Labial protuberances can 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 it is persistent, alveoloplasty may be necessary for treatment. This review provides a summary on the occurrence hypothesis, influencing factors of formation, potential biological mechanisms, and corresponding treatment methods of labial protuberances during orthodontic treatment.
