Mucogingival considerations following orthodontic therapy: a case report

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.
