A healthy periodontium is a prerequisite for any orthodontic intervention to be executed. However, application of orthodontic forces without thoughtful planning can result in not only damage to the attachment apparatus, but also alterations to the associated mucogingival tissues. This article elucidates a case of Miller's Class III gingival recession that developed in relation to the patient's lower right central incisor following orthodontic therapy. Case evaluation pertaining to gingival thickness, the level of underlying alveolar bone, and the inflammatory status of the tissues is critical to avoid the development of such soft-tissue defects. Options for augmentation of such sites prior to application of forces can be explored only if accurate diagnosis and clinical assessment are completed. This concept holds relevance for the treating dentist to identify cases with thin gingival tissue biotype and the propensity for developing dehiscence in order to prevent such mucogingival deformities from becoming established.
健康的牙周组织是进行任何正畸干预的前提条件。然而，未经周密规划就施加正畸力不仅会损害附着装置，还会改变相关的龈黏膜组织。本文阐述了一例正畸治疗后患者右下中切牙出现米勒III类牙龈退缩的病例。评估牙龈厚度、下方牙槽骨水平以及组织的炎症状态对于避免此类软组织缺陷的发生至关重要。只有在完成准确诊断和临床评估后，才可以探索在施力前对这些部位进行增量处理的方法。这一理念对于治疗牙医识别牙龈组织生物型薄且有发生裂开倾向的病例具有重要意义，以便防止此类龈黏膜畸形的形成。
